The primary way of interacting with a promise is through its `then` method, which registers callbacks to receive either a promise's eventual value or the reason why the promise cannot be fulfilled. Terminology ----------- - `promise` is an object or function with a `then` method whose behavior conforms to this specification. - `thenable` is an object or function that defines a `then` method. - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). - `exception` is a value that is thrown using the throw statement. - `reason` is a value that indicates why a promise was rejected. - `settled` the final resting state of a promise, fulfilled or rejected. A promise can be in one of three states: pending, fulfilled, or rejected. Promises that are fulfilled have a fulfillment value and are in the fulfilled state. Promises that are rejected have a rejection reason and are in the rejected state. A fulfillment value is never a thenable. Promises can also be said to *resolve* a value. If this value is also a promise, then the original promise's settled state will match the value's settled state. So a promise that *resolves* a promise that rejects will itself reject, and a promise that *resolves* a promise that fulfills will itself fulfill. Basic Usage: ------------ ```js let promise = new Promise(function(resolve, reject) { // on success resolve(value); // on failure reject(reason); }); promise.then(function(value) { // on fulfillment }, function(reason) { // on rejection }); ``` Advanced Usage: --------------- Promises shine when abstracting away asynchronous interactions such as `XMLHttpRequest`s. ```js function getJSON(url) { return new Promise(function(resolve, reject){ let xhr = new XMLHttpRequest(); xhr.open('GET', url); xhr.onreadystatechange = handler; xhr.responseType = 'json'; xhr.setRequestHeader('Accept', 'application/json'); xhr.send(); function handler() { if (this.readyState === this.DONE) { if (this.status === 200) { resolve(this.response); } else { reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); } } }; }); } getJSON('/posts.json').then(function(json) { // on fulfillment }, function(reason) { // on rejection }); ``` Unlike callbacks, promises are great composable primitives. ```js Promise.all([ getJSON('/posts'), getJSON('/comments') ]).then(function(values){ values[0] // => postsJSON values[1] // => commentsJSON return values; }); ``` @class Promise @param {Function} resolver Useful for tooling. @constructor */ var Promise$2 = function () { function Promise(resolver) { this[PROMISE_ID] = nextId(); this._result = this._state = undefined; this._subscribers = []; if (noop !== resolver) { typeof resolver !== 'function' && needsResolver(); this instanceof Promise ? initializePromise(this, resolver) : needsNew(); } } /** The primary way of interacting with a promise is through its `then` method, which registers callbacks to receive either a promise's eventual value or the reason why the promise cannot be fulfilled. ```js findUser().then(function(user){ // user is available }, function(reason){ // user is unavailable, and you are given the reason why }); ``` Chaining -------- The return value of `then` is itself a promise. This second, 'downstream' promise is resolved with the return value of the first promise's fulfillment or rejection handler, or rejected if the handler throws an exception. ```js findUser().then(function (user) { return user.name; }, function (reason) { return 'default name'; }).then(function (userName) { // If `findUser` fulfilled, `userName` will be the user's name, otherwise it // will be `'default name'` }); findUser().then(function (user) { throw new Error('Found user, but still unhappy'); }, function (reason) { throw new Error('`findUser` rejected and we're unhappy'); }).then(function (value) { // never reached }, function (reason) { // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'. }); ``` If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. ```js findUser().then(function (user) { throw new PedagogicalException('Upstream error'); }).then(function (value) { // never reached }).then(function (value) { // never reached }, function (reason) { // The `PedgagocialException` is propagated all the way down to here }); ``` Assimilation ------------ Sometimes the value you want to propagate to a downstream promise can only be retrieved asynchronously. This can be achieved by returning a promise in the fulfillment or rejection handler. The downstream promise will then be pending until the returned promise is settled. This is called *assimilation*. ```js findUser().then(function (user) { return findCommentsByAuthor(user); }).then(function (comments) { // The user's comments are now available }); ``` If the assimliated promise rejects, then the downstream promise will also reject. ```js findUser().then(function (user) { return findCommentsByAuthor(user); }).then(function (comments) { // If `findCommentsByAuthor` fulfills, we'll have the value here }, function (reason) { // If `findCommentsByAuthor` rejects, we'll have the reason here }); ``` Simple Example -------------- Synchronous Example ```javascript let result; try { result = findResult(); // success } catch(reason) { // failure } ``` Errback Example ```js findResult(function(result, err){ if (err) { // failure } else { // success } }); ``` Promise Example; ```javascript findResult().then(function(result){ // success }, function(reason){ // failure }); ``` Advanced Example -------------- Synchronous Example ```javascript let author, books; try { author = findAuthor(); books = findBooksByAuthor(author); // success } catch(reason) { // failure } ``` Errback Example ```js function foundBooks(books) { } function failure(reason) { } findAuthor(function(author, err){ if (err) { failure(err); // failure } else { try { findBoooksByAuthor(author, function(books, err) { if (err) { failure(err); } else { try { foundBooks(books); } catch(reason) { failure(reason); } } }); } catch(error) { failure(err); } // success } }); ``` Promise Example; ```javascript findAuthor(). then(findBooksByAuthor). then(function(books){ // found books }).catch(function(reason){ // something went wrong }); ``` @method then @param {Function} onFulfilled @param {Function} onRejected Useful for tooling. @return {Promise} */ /** `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same as the catch block of a try/catch statement. ```js function findAuthor(){ throw new Error('couldn't find that author'); } // synchronous try { findAuthor(); } catch(reason) { // something went wrong } // async with promises findAuthor().catch(function(reason){ // something went wrong }); ``` @method catch @param {Function} onRejection Useful for tooling. @return {Promise} */ Promise.prototype.catch = function _catch(onRejection) { return this.then(null, onRejection); }; /** `finally` will be invoked regardless of the promise's fate just as native try/catch/finally behaves Synchronous example: ```js findAuthor() { if (Math.random() > 0.5) { throw new Error(); } return new Author(); } try { return findAuthor(); // succeed or fail } catch(error) { return findOtherAuther(); } finally { // always runs // doesn't affect the return value } ``` Asynchronous example: ```js findAuthor().catch(function(reason){ return findOtherAuther(); }).finally(function(){ // author was either found, or not }); ``` @method finally @param {Function} callback @return {Promise} */ Promise.prototype.finally = function _finally(callback) { var promise = this; var constructor = promise.constructor; return promise.then(function (value) { return constructor.resolve(callback()).then(function () { return value; }); }, function (reason) { return constructor.resolve(callback()).then(function () { throw reason; }); }); }; return Promise; }(); Promise$2.prototype.then = then; Promise$2.all = all; Promise$2.race = race; Promise$2.resolve = resolve$1; Promise$2.reject = reject$1; Promise$2._setScheduler = setScheduler; Promise$2._setAsap = setAsap; Promise$2._asap = asap; /*global self*/ function polyfill() { var local = void 0; if (typeof global !== 'undefined') { local = global; } else if (typeof self !== 'undefined') { local = self; } else { try { local = Function('return this')(); } catch (e) { throw new Error('polyfill failed because global object is unavailable in this environment'); } } var P = local.Promise; if (P) { var promiseToString = null; try { promiseToString = Object.prototype.toString.call(P.resolve()); } catch (e) { // silently ignored } if (promiseToString === '[object Promise]' && !P.cast) { return; } } local.Promise = Promise$2; } // Strange compat..

If jQuery is not available, `angular.element` * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**. * * jqLite is a tiny, API-compatible subset of jQuery that allows * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most * commonly needed functionality with the goal of having a very small footprint. * * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a * specific version of jQuery if multiple versions exist on the page. * *
**Note:** All element references in Angular are always wrapped with jQuery or * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.
* *
**Note:** Keep in mind that this function will not find elements * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)` * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.
* * ## Angular's jqLite * jqLite provides only the following jQuery methods: * * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument * - [`after()`](http://api.jquery.com/after/) * - [`append()`](http://api.jquery.com/append/) * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData * - [`children()`](http://api.jquery.com/children/) - Does not support selectors * - [`clone()`](http://api.jquery.com/clone/) * - [`contents()`](http://api.jquery.com/contents/) * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`. * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing. * - [`data()`](http://api.jquery.com/data/) * - [`detach()`](http://api.jquery.com/detach/) * - [`empty()`](http://api.jquery.com/empty/) * - [`eq()`](http://api.jquery.com/eq/) * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name * - [`hasClass()`](http://api.jquery.com/hasClass/) * - [`html()`](http://api.jquery.com/html/) * - [`next()`](http://api.jquery.com/next/) - Does not support selectors * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors * - [`prepend()`](http://api.jquery.com/prepend/) * - [`prop()`](http://api.jquery.com/prop/) * - [`ready()`](http://api.jquery.com/ready/) * - [`remove()`](http://api.jquery.com/remove/) * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument * - [`removeData()`](http://api.jquery.com/removeData/) * - [`replaceWith()`](http://api.jquery.com/replaceWith/) * - [`text()`](http://api.jquery.com/text/) * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces or event object as parameter * - [`val()`](http://api.jquery.com/val/) * - [`wrap()`](http://api.jquery.com/wrap/) * * ## jQuery/jqLite Extras * Angular also provides the following additional methods and events to both jQuery and jqLite: * * ### Events * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM * element before it is removed. * * ### Methods * - `controller(name)` - retrieves the controller of the current element or its parent. By default * retrieves controller associated with the `ngController` directive. If `name` is provided as * camelCase directive name, then the controller for this directive will be retrieved (e.g. * `'ngModel'`). * - `injector()` - retrieves the injector of the current element or its parent. * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to * be enabled. * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the * current element. This getter should be used only on elements that contain a directive which starts a new isolate * scope. Calling `scope()` on this element always returns the original non-isolate scope. * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled. * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top * parent element is reached. * * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See * https://github.com/angular/angular.js/issues/14251 for more information. * * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery. * @returns {Object} jQuery object. */ JQLite.expando = 'ng339'; var jqCache = JQLite.cache = {}, jqId = 1, addEventListenerFn = function(element, type, fn) { element.addEventListener(type, fn, false); }, removeEventListenerFn = function(element, type, fn) { element.removeEventListener(type, fn, false); }; /* * !!!

* **Note:** This document is an in-depth reference of all directive options. * For a gentle introduction to directives with examples of common use cases, * see the {@link guide/directive directive guide}. *
* * ## Comprehensive Directive API * * There are many different options for a directive. * * The difference resides in the return value of the factory function. * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)} * that defines the directive properties, or just the `postLink` function (all other properties will have * the default values). * *
* **Best Practice:** It's recommended to use the "directive definition object" form. *
* * Here's an example directive declared with a Directive Definition Object: * * ```js * var myModule = angular.module(...); * * myModule.directive('directiveName', function factory(injectables) { * var directiveDefinitionObject = { * {@link $compile#-priority- priority}: 0, * {@link $compile#-template- template}: '
', // or // function(tElement, tAttrs) { ... }, * // or * // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... }, * {@link $compile#-transclude- transclude}: false, * {@link $compile#-restrict- restrict}: 'A', * {@link $compile#-templatenamespace- templateNamespace}: 'html', * {@link $compile#-scope- scope}: false, * {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... }, * {@link $compile#-controlleras- controllerAs}: 'stringIdentifier', * {@link $compile#-bindtocontroller- bindToController}: false, * {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'], * {@link $compile#-multielement- multiElement}: false, * {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) { * return { * {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... }, * {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... } * } * // or * // return function postLink( ... ) { ... } * }, * // or * // {@link $compile#-link- link}: { * // {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... }, * // {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... } * // } * // or * // {@link $compile#-link- link}: function postLink( ... ) { ... } * }; * return directiveDefinitionObject; * }); * ``` * *
* **Note:** Any unspecified options will use the default value. You can see the default values below. *
* * Therefore the above can be simplified as: * * ```js * var myModule = angular.module(...); * * myModule.directive('directiveName', function factory(injectables) { * var directiveDefinitionObject = { * link: function postLink(scope, iElement, iAttrs) { ... } * }; * return directiveDefinitionObject; * // or * // return function postLink(scope, iElement, iAttrs) { ... } * }); * ``` * * ### Life-cycle hooks * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the * directive: * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and * had their bindings initialized (and before the pre & post linking functions for the directives on * this element). This is a good place to put initialization code for your controller. * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a * component such as cloning the bound value to prevent accidental mutation of the outer value. * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on * changes. Any actions that you wish to take in response to the changes that you detect must be * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not * be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments; * if detecting changes, you must store the previous value(s) for comparison to the current values. * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent * components will have their `$onDestroy()` hook called before child components. * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link * function this hook can be used to set up DOM event handlers and do direct DOM manipulation. * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since * they are waiting for their template to load asynchronously and their own compilation and linking has been * suspended until that occurs. * * #### Comparison with Angular 2 life-cycle hooks * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2: * * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`. * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor. * In Angular 2 you can only define hooks on the prototype of the Component class. * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to * `ngDoCheck` in Angular 2 * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be * propagated throughout the application. * Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an * error or do nothing depending upon the state of `enableProdMode()`. * * #### Life-cycle hook examples * * This example shows how you can check for mutations to a Date object even though the identity of the object * has not changed. * * * * angular.module('do-check-module', []) * .component('app', { * template: * 'Month: ' + * 'Date: {{ $ctrl.date }}' + * '', * controller: function() { * this.date = new Date(); * this.month = this.date.getMonth(); * this.updateDate = function() { * this.date.setMonth(this.month); * }; * } * }) * .component('test', { * bindings: { date: '<' }, * template: * '
{{ $ctrl.log | json }}
', * controller: function() { * var previousValue; * this.log = []; * this.$doCheck = function() { * var currentValue = this.date && this.date.valueOf(); * if (previousValue !== currentValue) { * this.log.push('doCheck: date mutated: ' + this.date); * previousValue = currentValue; * } * }; * } * }); *
* * * *
* * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large * arrays or objects can have a negative impact on your application performance) * * * *
* * *
{{ items }}
* *
*
* * angular.module('do-check-module', []) * .component('test', { * bindings: { items: '<' }, * template: * '
{{ $ctrl.log | json }}
', * controller: function() { * this.log = []; * * this.$doCheck = function() { * if (this.items_ref !== this.items) { * this.log.push('doCheck: items changed'); * this.items_ref = this.items; * } * if (!angular.equals(this.items_clone, this.items)) { * this.log.push('doCheck: items mutated'); * this.items_clone = angular.copy(this.items); * } * }; * } * }); *
*
* * * ### Directive Definition Object * * The directive definition object provides instructions to the {@link ng.$compile * compiler}. The attributes are: * * #### `multiElement` * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them * together as the directive elements. It is recommended that this feature be used on directives * which are not strictly behavioral (such as {@link ngClick}), and which * do not manipulate or replace child nodes (such as {@link ngInclude}). * * #### `priority` * When there are multiple directives defined on a single DOM element, sometimes it * is necessary to specify the order in which the directives are applied. The `priority` is used * to sort the directives before their `compile` functions get called. Priority is defined as a * number. Directives with greater numerical `priority` are compiled first. Pre-link functions * are also run in priority order, but post-link functions are run in reverse order. The order * of directives with the same priority is undefined. The default priority is `0`. * * #### `terminal` * If set to true then the current `priority` will be the last set of directives * which will execute (any directives at the current priority will still execute * as the order of execution on same `priority` is undefined). Note that expressions * and other directives used in the directive's template will also be excluded from execution. * * #### `scope` * The scope property can be `false`, `true`, or an object: * * * **`false` (default):** No scope will be created for the directive. The directive will use its * parent's scope. * * * **`true`:** A new child scope that prototypically inherits from its parent will be created for * the directive's element. If multiple directives on the same element request a new scope, * only one new scope is created. * * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent * scope. This is useful when creating reusable components, which should not accidentally read or modify * data in the parent scope. * * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the * directive's element. These local properties are useful for aliasing values for templates. The keys in * the object hash map to the name of the property on the isolate scope; the values define how the property * is bound to the parent scope, via matching attributes on the directive's element: * * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is * always a string since DOM attributes are strings. If no `attr` name is specified then the * attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`, * the directive's scope property `localName` will reflect the interpolated value of `hello * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's * scope. The `name` is read from the parent scope (not the directive's scope). * * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope. * If no `attr` name is specified then the attribute name is assumed to be the same as the local * name. Given `` and the isolate scope definition `scope: { * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in * `localModel` and vice versa. Optional attributes should be marked as such with a question mark: * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`}) * will be thrown upon discovering changes to the local value, since it will be impossible to sync * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`} * method is used for tracking changes, and the equality check is based on object identity. * However, if an object literal or an array literal is passed as the binding expression, the * equality check is done by value (using the {@link angular.equals} function). It's also possible * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection * `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional). * * * `<` or `` and directive definition of * `scope: { localModel:'` and the isolate scope definition `scope: { * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope * via an expression to the parent scope. This can be done by passing a map of local variable names * and values into the expression wrapper fn. For example, if the expression is `increment(amount)` * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`. * * In general it's possible to apply more than one directive to one element, but there might be limitations * depending on the type of scope required by the directives. The following points will help explain these limitations. * For simplicity only two directives are taken into account, but it is also applicable for several directives: * * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope * * **child scope** + **no scope** => Both directives will share one single child scope * * **child scope** + **child scope** => Both directives will share one single child scope * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use * its parent's scope * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot * be applied to the same element. * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives * cannot be applied to the same element. * * * #### `bindToController` * This property is used to bind scope properties directly to the controller. It can be either * `true` or an object hash with the same format as the `scope` property. * * When an isolate scope is used for a directive (see above), `bindToController: true` will * allow a component to have its properties bound to the controller, rather than to scope. * * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller * properties. You can access these bindings once they have been initialized by providing a controller method called * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings * initialized. * *
* **Deprecation warning:** although bindings for non-ES6 class controllers are currently * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization * code that relies upon bindings inside a `$onInit` method on the controller, instead. *
* * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property. * This will set up the scope bindings to the controller directly. Note that `scope` can still be used * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate * scope (useful for component directives). * * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`. * * * #### `controller` * Controller constructor function. The controller is instantiated before the * pre-linking phase and can be accessed by other directives (see * `require` attribute). This allows the directives to communicate with each other and augment * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: * * * `$scope` - Current scope associated with the element * * `$element` - Current element * * `$attrs` - Current attributes object for the element * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: * `function([scope], cloneLinkingFn, futureParentElement, slotName)`: * * `scope`: (optional) override the scope. * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content. * * `futureParentElement` (optional): * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) * and when the `cloneLinkingFn` is passed, * as those elements need to created and cloned in a special way when they are defined outside their * usual containers (e.g. like ``). * * See also the `directive.templateNamespace` property. * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`) * then the default transclusion is provided. * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns * `true` if the specified slot contains content (i.e. one or more DOM nodes). * * #### `require` * Require another directive and inject its controller as the fourth argument to the linking function. The * `require` property can be a string, an array or an object: * * a **string** containing the name of the directive to pass to the linking function * * an **array** containing the names of directives to pass to the linking function. The argument passed to the * linking function will be an array of controllers in the same order as the names in the `require` property * * an **object** whose property values are the names of the directives to pass to the linking function. The argument * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding * controllers. * * If the `require` property is an object and `bindToController` is truthy, then the required controllers are * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers * have been constructed but before `$onInit` is called. * If the name of the required controller is the same as the local name (the key), the name can be * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`. * See the {@link $compileProvider#component} helper for an example of how this can be used. * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is * raised (unless no link function is specified and the required controllers are not being bound to the directive * controller, in which case error checking is skipped). The name can be prefixed with: * * * (no prefix) - Locate the required controller on the current element. Throw an error if not found. * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found. * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass * `null` to the `link` fn if not found. * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass * `null` to the `link` fn if not found. * * * #### `controllerAs` * Identifier name for a reference to the controller in the directive's scope. * This allows the controller to be referenced from the directive template. This is especially * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the * `controllerAs` reference might overwrite a property that already exists on the parent scope. * * * #### `restrict` * String of subset of `EACM` which restricts the directive to a specific directive * declaration style. If omitted, the defaults (elements and attributes) are used. * * * `E` - Element name (default): `` * * `A` - Attribute (default): `
` * * `C` - Class: `
` * * `M` - Comment: `` * * * #### `templateNamespace` * String representing the document type used by the markup in the template. * AngularJS needs this information as those elements need to be created and cloned * in a special way when they are defined outside their usual containers like `` and ``. * * * `html` - All root nodes in the template are HTML. Root nodes may also be * top-level elements such as `` or ``. * * `svg` - The root nodes in the template are SVG elements (excluding ``). * * `math` - The root nodes in the template are MathML elements (excluding ``). * * If no `templateNamespace` is specified, then the namespace is considered to be `html`. * * #### `template` * HTML markup that may: * * Replace the contents of the directive's element (default). * * Replace the directive's element itself (if `replace` is true - DEPRECATED). * * Wrap the contents of the directive's element (if `transclude` is true). * * Value may be: * * * A string. For example `
{{delete_str}}
`. * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` * function api below) and returns a string value. * * * #### `templateUrl` * This is similar to `template` but the template is loaded from the specified URL, asynchronously. * * Because template loading is asynchronous the compiler will suspend compilation of directives on that element * for later when the template has been resolved. In the meantime it will continue to compile and link * sibling and parent elements as though this element had not contained any directives. * * The compiler does not suspend the entire compilation to wait for templates to be loaded because this * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the * case when only one deeply nested directive has `templateUrl`. * * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache} * * You can specify `templateUrl` as a string representing the URL or as a function which takes two * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns * a string value representing the url. In either case, the template URL is passed through {@link * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. * * * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0) * specify what the template should replace. Defaults to `false`. * * * `true` - the template will replace the directive's element. * * `false` - the template will replace the contents of the directive's element. * * The replacement process migrates all of the attributes / classes from the old element to the new * one. See the {@link guide/directive#template-expanding-directive * Directives Guide} for an example. * * There are very few scenarios where element replacement is required for the application function, * the main one being reusable custom components that are used within SVG contexts * (because SVG doesn't work with custom elements in the DOM tree). * * #### `transclude` * Extract the contents of the element where the directive appears and make it available to the directive. * The contents are compiled and provided to the directive as a **transclusion function**. See the * {@link $compile#transclusion Transclusion} section below. * * * #### `compile` * * ```js * function compile(tElement, tAttrs, transclude) { ... } * ``` * * The compile function deals with transforming the template DOM. Since most directives do not do * template transformation, it is not used often. The compile function takes the following arguments: * * * `tElement` - template element - The element where the directive has been declared. It is * safe to do template transformation on the element and child elements only. * * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared * between all directive compile functions. * * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)` * *
* **Note:** The template instance and the link instance may be different objects if the template has * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration * should be done in a linking function rather than in a compile function. *
*
* **Note:** The compile function cannot handle directives that recursively use themselves in their * own templates or compile functions. Compiling these directives results in an infinite loop and * stack overflow errors. * * This can be avoided by manually using $compile in the postLink function to imperatively compile * a directive's template instead of relying on automatic template compilation via `template` or * `templateUrl` declaration or manual compilation inside the compile function. *
* *
* **Note:** The `transclude` function that is passed to the compile function is deprecated, as it * e.g. does not know about the right outer scope. Please use the transclude function that is passed * to the link function instead. *
* A compile function can have a return value which can be either a function or an object. * * * returning a (post-link) function - is equivalent to registering the linking function via the * `link` property of the config object when the compile function is empty. * * * returning an object with function(s) registered via `pre` and `post` properties - allows you to * control when a linking function should be called during the linking phase. See info about * pre-linking and post-linking functions below. * * * #### `link` * This property is used only if the `compile` property is not defined. * * ```js * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } * ``` * * The link function is responsible for registering DOM listeners as well as updating the DOM. It is * executed after the template has been cloned. This is where most of the directive logic will be * put. * * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the * directive for registering {@link ng.$rootScope.Scope#$watch watches}. * * * `iElement` - instance element - The element where the directive is to be used. It is safe to * manipulate the children of the element only in `postLink` function since the children have * already been linked. * * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared * between all directive linking functions. * * * `controller` - the directive's required controller instance(s) - Instances are shared * among all directives, which allows the directives to use the controllers as a communication * channel. The exact value depends on the directive's `require` property: * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one * * `string`: the controller instance * * `array`: array of controller instances * * If a required controller cannot be found, and it is optional, the instance is `null`, * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown. * * Note that you can also require the directive's own controller - it will be made available like * any other controller. * * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. * This is the same as the `$transclude` parameter of directive controllers, * see {@link ng.$compile#-controller- the controller section for details}. * `function([scope], cloneLinkingFn, futureParentElement)`. * * #### Pre-linking function * * Executed before the child elements are linked. Not safe to do DOM transformation since the * compiler linking function will fail to locate the correct elements for linking. * * #### Post-linking function * * Executed after the child elements are linked. * * Note that child elements that contain `templateUrl` directives will not have been compiled * and linked since they are waiting for their template to load asynchronously and their own * compilation and linking has been suspended until that occurs. * * It is safe to do DOM transformation in the post-linking function on elements that are not waiting * for their async templates to be resolved. * * * ### Transclusion * * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and * copying them to another part of the DOM, while maintaining their connection to the original AngularJS * scope from where they were taken. * * Transclusion is used (often with {@link ngTransclude}) to insert the * original contents of a directive's element into a specified place in the template of the directive. * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded * content has access to the properties on the scope from which it was taken, even if the directive * has isolated scope. * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}. * * This makes it possible for the widget to have private state for its template, while the transcluded * content has access to its originating scope. * *
* **Note:** When testing an element transclude directive you must not place the directive at the root of the * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives * Testing Transclusion Directives}. *
* * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the * directive's element, the entire element or multiple parts of the element contents: * * * `true` - transclude the content (i.e. the child nodes) of the directive's element. * * `'element'` - transclude the whole of the directive's element including any directives on this * element that defined at a lower priority than this directive. When used, the `template` * property is ignored. * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template. * * **Mult-slot transclusion** is declared by providing an object for the `transclude` property. * * This object is a map where the keys are the name of the slot to fill and the value is an element selector * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`) * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc). * * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives} * * If the element selector is prefixed with a `?` then that slot is optional. * * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive. * * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and * injectable into the directive's controller. * * * #### Transclusion Functions * * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion * function** to the directive's `link` function and `controller`. This transclusion function is a special * **linking function** that will return the compiled contents linked to a new transclusion scope. * *
* If you are just using {@link ngTransclude} then you don't need to worry about this function, since * ngTransclude will deal with it for us. *
* * If you want to manually control the insertion and removal of the transcluded content in your directive * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery * object that contains the compiled DOM, which is linked to the correct transclusion scope. * * When you call a transclusion function you can pass in a **clone attach function**. This function accepts * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded * content and the `scope` is the newly created transclusion scope, which the clone will be linked to. * *
* **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope. *
* * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone * attach function**: * * ```js * var transcludedContent, transclusionScope; * * $transclude(function(clone, scope) { * element.append(clone); * transcludedContent = clone; * transclusionScope = scope; * }); * ``` * * Later, if you want to remove the transcluded content from your DOM then you should also destroy the * associated transclusion scope: * * ```js * transcludedContent.remove(); * transclusionScope.$destroy(); * ``` * *
* **Best Practice**: if you intend to add and remove transcluded content manually in your directive * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it), * then you are also responsible for calling `$destroy` on the transclusion scope. *
* * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} * automatically destroy their transcluded clones as necessary so you do not need to worry about this if * you are simply using {@link ngTransclude} to inject the transclusion into your directive. * * * #### Transclusion Scopes * * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it * was taken. * * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look * like this: * * ```html *
*
*
*
*
*
* ``` * * The `$parent` scope hierarchy will look like this: * ``` - $rootScope - isolate - transclusion ``` * * but the scopes will inherit prototypically from different scopes to their `$parent`. * ``` - $rootScope - transclusion - isolate ``` * * * ### Attributes * * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the * `link()` or `compile()` functions. It has a variety of uses. * * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways: * 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access * to the attributes. * * * *Directive inter-communication:* All directives share the same instance of the attributes * object which allows the directives to use the attributes object as inter directive * communication. * * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object * allowing other directives to read the interpolated value. * * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also * the only way to easily get the actual value because during the linking phase the interpolation * hasn't been evaluated yet and so the value is at this time set to `undefined`. * * ```js * function linkingFn(scope, elm, attrs, ctrl) { * // get the attribute value * console.log(attrs.ngModel); * * // change the attribute * attrs.$set('ngModel', 'new value'); * * // observe changes to interpolated attribute * attrs.$observe('ngModel', function(value) { * console.log('ngModel has changed value to ' + value); * }); * } * ``` * * ## Example * *
* **Note**: Typically directives are registered with `module.directive`. The example below is * to illustrate how `$compile` works. *
*


it('should auto compile', function() { var textarea = $('textarea'); var output = $('div[compile]'); // The initial state reads 'Hello Angular'. expect(output.getText()).toBe('Hello Angular'); textarea.clear(); textarea.sendKeys('{{name}}!'); expect(output.getText()).toBe('Angular!'); });
* * * @param {string|DOMElement} element Element or HTML string to compile into a template function. * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED. * *
* **Note:** Passing a `transclude` function to the $compile function is deprecated, as it * e.g. will not use the right outer scope. Please pass the transclude function as a * `parentBoundTranscludeFn` to the link function instead. *
* * @param {number} maxPriority only apply directives lower than given priority (Only effects the * root element(s), not their children) * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template * (a DOM element/tree) to a scope. Where: * * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to. * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the * `template` and call the `cloneAttachFn` function allowing the caller to attach the * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is * called as:
`cloneAttachFn(clonedElement, scope)` where: * * * `clonedElement` - is a clone of the original `element` passed into the compiler. * * `scope` - is the current scope with which the linking function is working with. * * * `options` - An optional object hash with linking options. If `options` is provided, then the following * keys may be used to control linking behavior: * * * `parentBoundTranscludeFn` - the transclude function made available to * directives; if given, it will be passed through to the link functions of * directives found in `element` during compilation. * * `transcludeControllers` - an object hash with keys that map controller names * to a hash with the key `instance`, which maps to the controller instance; * if given, it will make the controllers available to directives on the compileNode: * ``` * { * parent: { * instance: parentControllerInstance * } * } * ``` * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add * the cloned elements; only needed for transcludes that are allowed to contain non html * elements (e.g. SVG elements). See also the directive.controller property. * * Calling the linking function returns the element of the template. It is either the original * element passed in, or the clone of the element if the `cloneAttachFn` is provided. * * After linking the view is not updated until after a call to $digest which typically is done by * Angular automatically. * * If you need access to the bound view, there are two ways to do it: * * - If you are not asking the linking function to clone the template, create the DOM element(s) * before you send them to the compiler and keep this reference around. * ```js * var element = $compile('

{{total}}

')(scope); * ``` * * - if on the other hand, you need the element to be cloned, the view reference from the original * example would not point to the clone, but rather to the original template that was cloned. In * this case, you can access the clone via the cloneAttachFn: * ```js * var templateElement = angular.element('

{{total}}

'), * scope = ....; * * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) { * //attach the clone to DOM document at the right place * }); * * //now we have reference to the cloned DOM via `clonedElement` * ``` * * * For information on how the compiler works, see the * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide. * * @knownIssue * * ### Double Compilation * Double compilation occurs when an already compiled part of the DOM gets compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues, and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it section on double compilation} for an in-depth explanation and ways to avoid it. * */ var $compileMinErr = minErr('$compile'); function UNINITIALIZED_VALUE() {} var _UNINITIALIZED_VALUE = new UNINITIALIZED_VALUE(); /** * @ngdoc provider * @name $compileProvider * * @description */ $CompileProvider.$inject = ['$provide', '$$sanitizeUriProvider']; /** @this */ function $CompileProvider($provide, $$sanitizeUriProvider) { var hasDirectives = {}, Suffix = 'Directive', COMMENT_DIRECTIVE_REGEXP = /^\s*directive:\s*([\w-]+)\s+(.*)$/, CLASS_DIRECTIVE_REGEXP = /(([\w-]+)(?::([^;]+))?;?)/, ALL_OR_NOTHING_ATTRS = makeMap('ngSrc,ngSrcset,src,srcset'), REQUIRE_PREFIX_REGEXP = /^(?:(\^\^?)?(\?)?(\^\^?)?)?/; // Ref: http://developers.whatwg.org/webappapis.html#event-handler-idl-attributes // The assumption is that future DOM event attribute names will begin with // 'on' and be composed of only English letters. var EVENT_HANDLER_ATTR_REGEXP = /^(on[a-z]+|formaction)$/; var bindingCache = createMap(); function parseIsolateBindings(scope, directiveName, isController) { var LOCAL_REGEXP = /^\s*([@&<]|=(\*?))(\??)\s*([\w$]*)\s*$/; var bindings = createMap(); forEach(scope, function(definition, scopeName) { if (definition in bindingCache) { bindings[scopeName] = bindingCache[definition]; return; } var match = definition.match(LOCAL_REGEXP); if (!match) { throw $compileMinErr('iscp', 'Invalid {3} for directive \'{0}\'.' + ' Definition: {... {1}: \'{2}\' ...}', directiveName, scopeName, definition, (isController ?

While for simple usage patterns this doesn't matter much, for advanced usage * it is important to familiarize yourself with these APIs and the guarantees they provide. * * * ## General usage * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} — * that is used to generate an HTTP request and returns a {@link ng.$q promise}. * * ```js * // Simple GET request example: * $http({ * method: 'GET', * url: '/someUrl' * }).then(function successCallback(response) { * // this callback will be called asynchronously * // when the response is available * }, function errorCallback(response) { * // called asynchronously if an error occurs * // or server returns response with an error status. * }); * ``` * * The response object has these properties: * * - **data** – `{string|Object}` – The response body transformed with the transform * functions. * - **status** – `{number}` – HTTP status code of the response. * - **headers** – `{function([headerName])}` – Header getter function. * - **config** – `{Object}` – The configuration object that was used to generate the request. * - **statusText** – `{string}` – HTTP status text of the response. * * A response status code between 200 and 299 is considered a success status and will result in * the success callback being called. Any response status code outside of that range is * considered an error status and will result in the error callback being called. * Also, status codes less than -1 are normalized to zero. -1 usually means the request was * aborted, e.g. using a `config.timeout`. * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning * that the outcome (success or error) will be determined by the final response status code. * * * ## Shortcut methods * * Shortcut methods are also available. All shortcut methods require passing in the URL, and * request data must be passed in for POST/PUT requests. An optional config can be passed as the * last argument. * * ```js * $http.get('/someUrl', config).then(successCallback, errorCallback); * $http.post('/someUrl', data, config).then(successCallback, errorCallback); * ``` * * Complete list of shortcut methods: * * - {@link ng.$http#get $http.get} * - {@link ng.$http#head $http.head} * - {@link ng.$http#post $http.post} * - {@link ng.$http#put $http.put} * - {@link ng.$http#delete $http.delete} * - {@link ng.$http#jsonp $http.jsonp} * - {@link ng.$http#patch $http.patch} * * * ## Writing Unit Tests that use $http * When unit testing (using {@link ngMock ngMock}), it is necessary to call * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending * request using trained responses. * * ``` * $httpBackend.expectGET(...); * $http.get(...); * $httpBackend.flush(); * ``` * * ## Deprecation Notice *
* The `$http` legacy promise methods `success` and `error` have been deprecated and will be * removed in v1.6.0. * Use the standard `then` method instead. * If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to * `false` then these methods will throw {@link $http:legacy `$http/legacy`} error. *
* * ## Setting HTTP Headers * * The $http service will automatically add certain HTTP headers to all requests. These defaults * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration * object, which currently contains this default configuration: * * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): * - Accept: application/json, text/plain, \*/\* * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) * - `Content-Type: application/json` * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) * - `Content-Type: application/json` * * To add or overwrite these defaults, simply add or remove a property from these configuration * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object * with the lowercased HTTP method name as the key, e.g. * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`. * * The defaults can also be set at runtime via the `$http.defaults` object in the same * fashion. For example: * * ``` * module.run(function($http) { * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'; * }); * ``` * * In addition, you can supply a `headers` property in the config object passed when * calling `$http(config)`, which overrides the defaults without changing them globally. * * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, * Use the `headers` property, setting the desired header to `undefined`. For example: * * ```js * var req = { * method: 'POST', * url: 'http://example.com', * headers: { * 'Content-Type': undefined * }, * data: { test: 'test' } * } * * $http(req).then(function(){...}, function(){...}); * ``` * * ## Transforming Requests and Responses * * Both requests and responses can be transformed using transformation functions: `transformRequest` * and `transformResponse`. These properties can be a single function that returns * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions, * which allows you to `push` or `unshift` a new transformation function into the transformation chain. * *
* **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline. * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference). * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest * function will be reflected on the scope and in any templates where the object is data-bound. * To prevent this, transform functions should have no side-effects. * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return. *
* * ### Default Transformations * * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and * `defaults.transformResponse` properties. If a request does not provide its own transformations * then these will be applied. * * You can augment or replace the default transformations by modifying these properties by adding to or * replacing the array. * * Angular provides the following default transformations: * * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`): * * - If the `data` property of the request configuration object contains an object, serialize it * into JSON format. * * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`): * * - If XSRF prefix is detected, strip it (see Security Considerations section below). * - If JSON response is detected, deserialize it using a JSON parser. * * * ### Overriding the Default Transformations Per Request * * If you wish to override the request/response transformations only for a single request then provide * `transformRequest` and/or `transformResponse` properties on the configuration object passed * into `$http`. * * Note that if you provide these properties on the config object the default transformations will be * overwritten. If you wish to augment the default transformations then you must include them in your * local transformation array. * * The following code demonstrates adding a new response transformation to be run after the default response * transformations have been run. * * ```js * function appendTransform(defaults, transform) { * * // We can't guarantee that the default transformation is an array * defaults = angular.isArray(defaults) ? defaults : [defaults]; * * // Append the new transformation to the defaults * return defaults.concat(transform); * } * * $http({ * url: '...', * method: 'GET', * transformResponse: appendTransform($http.defaults.transformResponse, function(value) { * return doTransform(value); * }) * }); * ``` * * * ## Caching * * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must * set the config.cache value or the default cache value to TRUE or to a cache object (created * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes * precedence over the default cache value. * * In order to: * * cache all responses - set the default cache value to TRUE or to a cache object * * cache a specific response - set config.cache value to TRUE or to a cache object * * If caching is enabled, but neither the default cache nor config.cache are set to a cache object, * then the default `$cacheFactory("$http")` object is used. * * The default cache value can be set by updating the * {@link ng.$http#defaults `$http.defaults.cache`} property or the * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property. * * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using * the relevant cache object. The next time the same request is made, the response is returned * from the cache without sending a request to the server. * * Take note that: * * * Only GET and JSONP requests are cached. * * The cache key is the request URL including search parameters; headers are not considered. * * Cached responses are returned asynchronously, in the same way as responses from the server. * * If multiple identical requests are made using the same cache, which is not yet populated, * one request will be made to the server and remaining requests will return the same response. * * A cache-control header on the response does not affect if or how responses are cached. * * * ## Interceptors * * Before you start creating interceptors, be sure to understand the * {@link ng.$q $q and deferred/promise APIs}. * * For purposes of global error handling, authentication, or any kind of synchronous or * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be * able to intercept requests before they are handed to the server and * responses before they are handed over to the application code that * initiated these requests. The interceptors leverage the {@link ng.$q * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. * * The interceptors are service factories that are registered with the `$httpProvider` by * adding them to the `$httpProvider.interceptors` array. The factory is called and * injected with dependencies (if specified) and returns the interceptor. * * There are two kinds of interceptors (and two kinds of rejection interceptors): * * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to * modify the `config` object or create a new one. The function needs to return the `config` * object directly, or a promise containing the `config` or a new `config` object. * * `requestError`: interceptor gets called when a previous interceptor threw an error or * resolved with a rejection. * * `response`: interceptors get called with http `response` object. The function is free to * modify the `response` object or create a new one. The function needs to return the `response` * object directly, or as a promise containing the `response` or a new `response` object. * * `responseError`: interceptor gets called when a previous interceptor threw an error or * resolved with a rejection. * * * ```js * // register the interceptor as a service * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { * return { * // optional method * 'request': function(config) { * // do something on success * return config; * }, * * // optional method * 'requestError': function(rejection) { * // do something on error * if (canRecover(rejection)) { * return responseOrNewPromise * } * return $q.reject(rejection); * }, * * * * // optional method * 'response': function(response) { * // do something on success * return response; * }, * * // optional method * 'responseError': function(rejection) { * // do something on error * if (canRecover(rejection)) { * return responseOrNewPromise * } * return $q.reject(rejection); * } * }; * }); * * $httpProvider.interceptors.push('myHttpInterceptor'); * * * // alternatively, register the interceptor via an anonymous factory * $httpProvider.interceptors.push(function($q, dependency1, dependency2) { * return { * 'request': function(config) { * // same as above * }, * * 'response': function(response) { * // same as above * } * }; * }); * ``` * * ## Security Considerations * * When designing web applications, consider security threats from: * * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) * * Both server and the client must cooperate in order to eliminate these threats. Angular comes * pre-configured with strategies that address these issues, but for this to work backend server * cooperation is required. * * ### JSON Vulnerability Protection * * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) * allows third party website to turn your JSON resource URL into * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To * counter this your server can prefix all JSON requests with following string `")]}',\n"`. * Angular will automatically strip the prefix before processing it as JSON. * * For example if your server needs to return: * ```js * ['one','two'] * ``` * * which is vulnerable to attack, your server can return: * ```js * )]}', * ['one','two'] * ``` * * Angular will strip the prefix, before processing the JSON. * * * ### Cross Site Request Forgery (XSRF) Protection * * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by * which the attacker can trick an authenticated user into unknowingly executing actions on your * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the * cookie, your server can be assured that the XHR came from JavaScript running on your domain. * The header will not be set for cross-domain requests. * * To take advantage of this, your server needs to set a token in a JavaScript readable session * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure * that only JavaScript running on your domain could have sent the request. The token must be * unique for each user and must be verifiable by the server (to prevent the JavaScript from * making up its own tokens). We recommend that the token is a digest of your site's * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) * for added security. * * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time, * or the per-request config object. * * In order to prevent collisions in environments where multiple Angular apps share the * same domain or subdomain, we recommend that each application uses unique cookie name. * * @param {object} config Object describing the request to be made and how it should be * processed. The object has following properties: * * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested. * - **params** – `{Object.}` – Map of strings or objects which will be serialized * with the `paramSerializer` and appended as GET parameters. * - **data** – `{string|Object}` – Data to be sent as the request message data. * - **headers** – `{Object}` – Map of strings or functions which return strings representing * HTTP headers to send to the server. If the return value of a function is null, the * header will not be sent. Functions accept a config object as an argument. * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object. * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`. * The handler will be called in the context of a `$apply` block. * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload * object. To bind events to the XMLHttpRequest object, use `eventHandlers`. * The handler will be called in the context of a `$apply` block. * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token. * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token. * - **transformRequest** – * `{function(data, headersGetter)|Array.}` – * transform function or an array of such functions. The transform function takes the http * request body and headers and returns its transformed (typically serialized) version. * See {@link ng.$http#overriding-the-default-transformations-per-request * Overriding the Default Transformations} * - **transformResponse** – * `{function(data, headersGetter, status)|Array.}` – * transform function or an array of such functions. The transform function takes the http * response body, headers and status and returns its transformed (typically deserialized) version. * See {@link ng.$http#overriding-the-default-transformations-per-request * Overriding the Default Transformations} * - **paramSerializer** - `{string|function(Object):string}` - A function used to * prepare the string representation of request parameters (specified as an object). * If specified as string, it is interpreted as function registered with the * {@link $injector $injector}, which means you can create your own serializer * by registering it as a {@link auto.$provide#service service}. * The default serializer is the {@link $httpParamSerializer $httpParamSerializer}; * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike} * - **cache** – `{boolean|Object}` – A boolean value or object created with * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response. * See {@link $http#caching $http Caching} for more information. * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} * that should abort the request when resolved. * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials) * for more information. * - **responseType** - `{string}` - see * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype). * * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object * when the request succeeds or fails. * * * @property {Array.} pendingRequests Array of config objects for currently pending * requests.

So, for HTML elements interpolated * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such, * this is typically useful only when user-data is used in rendering a template from the server, or * when otherwise untrusted data is used by a directive. * * * *

* * @knownIssue * It is currently not possible for an interpolated expression to contain the interpolation end * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e. * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string. * * @knownIssue * All directives and components must use the standard `{{` `}}` interpolation symbols * in their templates. If you change the application interpolation symbols the {@link $compile} * service will attempt to denormalize the standard symbols to the custom symbols. * The denormalization process is not clever enough to know not to replace instances of the standard * symbols where they would not normally be treated as interpolation symbols. For example in the following * code snippet the closing braces of the literal object will get incorrectly denormalized: * * ``` *

This is similar to the native Promise implementation from ES6, * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). * * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are * available yet. * * It can be used like so: * * ```js * // for the purpose of this example let's assume that variables `$q` and `okToGreet` * // are available in the current lexical scope (they could have been injected or passed in). * * function asyncGreet(name) { * // perform some asynchronous operation, resolve or reject the promise when appropriate. * return $q(function(resolve, reject) { * setTimeout(function() { * if (okToGreet(name)) { * resolve('Hello, ' + name + '!'); * } else { * reject('Greeting ' + name + ' is not allowed.'); * } * }, 1000); * }); * } * * var promise = asyncGreet('Robin Hood'); * promise.then(function(greeting) { * alert('Success: ' + greeting); * }, function(reason) { * alert('Failed: ' + reason); * }); * ``` * * Note: progress/notify callbacks are not currently supported via the ES6-style interface. * * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise. * * However, the more traditional CommonJS-style usage is still available, and documented below. * * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an * interface for interacting with an object that represents the result of an action that is * performed asynchronously, and may or may not be finished at any given point in time. * * From the perspective of dealing with error handling, deferred and promise APIs are to * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. * * ```js * // for the purpose of this example let's assume that variables `$q` and `okToGreet` * // are available in the current lexical scope (they could have been injected or passed in). * * function asyncGreet(name) { * var deferred = $q.defer(); * * setTimeout(function() { * deferred.notify('About to greet ' + name + '.'); * * if (okToGreet(name)) { * deferred.resolve('Hello, ' + name + '!'); * } else { * deferred.reject('Greeting ' + name + ' is not allowed.'); * } * }, 1000); * * return deferred.promise; * } * * var promise = asyncGreet('Robin Hood'); * promise.then(function(greeting) { * alert('Success: ' + greeting); * }, function(reason) { * alert('Failed: ' + reason); * }, function(update) { * alert('Got notification: ' + update); * }); * ``` * * At first it might not be obvious why this extra complexity is worth the trouble. The payoff * comes in the way of guarantees that promise and deferred APIs make, see * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. * * Additionally the promise api allows for composition that is very hard to do with the * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the * section on serial or parallel joining of promises. * * # The Deferred API * * A new instance of deferred is constructed by calling `$q.defer()`. * * The purpose of the deferred object is to expose the associated Promise instance as well as APIs * that can be used for signaling the successful or unsuccessful completion, as well as the status * of the task. * * **Methods** * * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection * constructed via `$q.reject`, the promise will be rejected instead. * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to * resolving it with a rejection constructed via `$q.reject`. * - `notify(value)` - provides updates on the status of the promise's execution. This may be called * multiple times before the promise is either resolved or rejected. * * **Properties** * * - promise – `{Promise}` – promise object associated with this deferred. * * * # The Promise API * * A new promise instance is created when a deferred instance is created and can be retrieved by * calling `deferred.promise`. * * The purpose of the promise object is to allow for interested parties to get access to the result * of the deferred task when it completes. * * **Methods** * * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously * as soon as the result is available. The callbacks are called with a single argument: the result * or rejection reason. Additionally, the notify callback may be called zero or more times to * provide a progress indication, before the promise is resolved or rejected. * * This method *returns a new promise* which is resolved or rejected via the return value of the * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved * with the value which is resolved in that promise using * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). * It also notifies via the return value of the `notifyCallback` method. The promise cannot be * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback * arguments are optional. * * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` * * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, * but to do so without modifying the final value. This is useful to release resources or do some * clean-up that needs to be done whether the promise was rejected or resolved. See the [full * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for * more information. * * # Chaining promises * * Because calling the `then` method of a promise returns a new derived promise, it is easily * possible to create a chain of promises: * * ```js * promiseB = promiseA.then(function(result) { * return result + 1; * }); * * // promiseB will be resolved immediately after promiseA is resolved and its value * // will be the result of promiseA incremented by 1 * ``` * * It is possible to create chains of any length and since a promise can be resolved with another * promise (which will defer its resolution further), it is possible to pause/defer resolution of * the promises at any point in the chain. This makes it possible to implement powerful APIs like * $http's response interceptors. * * * # Differences between Kris Kowal's Q and $q * * There are two main differences: * * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation * mechanism in angular, which means faster propagation of resolution or rejection into your * models and avoiding unnecessary browser repaints, which would result in flickering UI. * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains * all the important functionality needed for common async tasks. * * # Testing * * ```js * it('should simulate promise', inject(function($q, $rootScope) { * var deferred = $q.defer(); * var promise = deferred.promise; * var resolvedValue; * * promise.then(function(value) { resolvedValue = value; }); * expect(resolvedValue).toBeUndefined(); * * // Simulate resolving of promise * deferred.resolve(123); * // Note that the 'then' function does not get called synchronously. * // This is because we want the promise API to always be async, whether or not * // it got called synchronously or asynchronously. * expect(resolvedValue).toBeUndefined(); * * // Propagate promise resolution to 'then' functions using $apply(). * $rootScope.$apply(); * expect(resolvedValue).toEqual(123); * })); * ``` * * @param {function(function, function)} resolver Function which is responsible for resolving or * rejecting the newly created promise.

That is, `watchExpression` should be * [idempotent](http://en.wikipedia.org/wiki/Idempotence).) * - The `listener` is called only when the value from the current `watchExpression` and the * previous call to `watchExpression` are not equal (with the exception of the initial run, * see below). Inequality is determined according to reference inequality, * [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators) * via the `!==` Javascript operator, unless `objectEquality == true` * (see next point) * - When `objectEquality == true`, inequality of the `watchExpression` is determined * according to the {@link angular.equals} function.

One example of * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer * to these contexts as privileged or SCE contexts. * * As of version 1.2, Angular ships with SCE enabled by default. * * Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow * one to execute arbitrary javascript by the use of the expression() syntax. Refer * to learn more about them. * You can ensure your document is in standards mode and not quirks mode by adding `` * to the top of your HTML document. * * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for * security vulnerabilities such as XSS, clickjacking, etc. a lot easier. * * Here's an example of a binding in a privileged context: * * ``` * *
* ``` * * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE * disabled, this application allows the user to render arbitrary HTML into the DIV. * In a more realistic example, one may be rendering user comments, blog articles, etc. via * bindings. (HTML is just one example of a context where rendering user controlled input creates * security vulnerabilities.) * * For the case of HTML, you might use a library, either on the client side, or on the server side, * to sanitize unsafe HTML before binding to the value and rendering it in the document. * * How would you ensure that every place that used these types of bindings was bound to a value that * was sanitized by your library (or returned as safe for rendering by your server?) How can you * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some * properties/fields and forgot to update the binding to the sanitized value? * * To be secure by default, you want to ensure that any such bindings are disallowed unless you can * determine that something explicitly says it's safe to use a value for binding in that * context. You can then audit your code (a simple grep would do) to ensure that this is only done * for those values that you can easily tell are safe - because they were received from your server, * sanitized by your library, etc. You can organize your codebase to help with this - perhaps * allowing only the files in a specific directory to do this. Ensuring that the internal API * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task. * * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to * obtain values that will be accepted by SCE / privileged contexts. * * * ## How does it work? * * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. * * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly * simplified): * * ``` * var ngBindHtmlDirective = ['$sce', function($sce) { * return function(scope, element, attr) { * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { * element.html(value || ''); * }); * }; * }]; * ``` * * ## Impact on loading templates * * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as * `templateUrl`'s specified by {@link guide/directive directives}. * * By default, Angular only loads templates from the same domain and protocol as the application * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. * * *Please note*: * The browser's * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) * policy apply in addition to this and may further restrict whether the template is successfully * loaded. This means that without the right CORS policy, loading templates from a different domain * won't work on all browsers. Also, loading templates from `file://` URL does not work on some * browsers. * * ## This feels like too much overhead * * It's important to remember that SCE only applies to interpolation expressions. * * If your expressions are constant literals, they're automatically trusted and you don't need to * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g. * `
`) just works. * * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here. * * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load * templates in `ng-include` from your application's domain without having to even know about SCE. * It blocks loading templates from other domains or loading templates over http from an https * served document. You can change these by setting your own custom {@link * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. * * This significantly reduces the overhead. It is far easier to pay the small overhead and have an * application that's secure and can be audited to verify that with much more ease than bolting * security onto an application later. * * * ## What trusted context types are supported? * * | Context | Notes | * |---------------------|----------------| * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. | * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | * * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist}
* * Each element in these arrays must be one of the following: * * - **'self'** * - The special **string**, `'self'`, can be used to match against all URLs of the **same * domain** as the application document using the **same protocol**. * - **String** (except the special value `'self'`) * - The string is matched against the full *normalized / absolute URL* of the resource * being tested (substring matches are not good enough.) * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters * match themselves. * - `*`: matches zero or more occurrences of any character other than one of the following 6 * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use * in a whitelist. * - `**`: matches zero or more occurrences of *any* character. As such, it's not * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might * not have been the intention.) Its usage at the very end of the path is ok. (e.g. * http://foo.example.com/templates/**). * - **RegExp** (*see caveat below*) * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to * accidentally introduce a bug when one updates a complex expression (imho, all regexes should * have good test coverage). For instance, the use of `.` in the regex is correct only in a * small number of cases. A `.` character in the regex used when matching the scheme or a * subdomain could be matched against a `:` or literal `.` that was likely not intended. It * is highly recommended to use the string patterns and only fall back to regular expressions * as a last resort. * - The regular expression must be an instance of RegExp (i.e. not a string.) It is * matched against the **entire** *normalized / absolute URL* of the resource being tested * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags * present on the RegExp (such as multiline, global, ignoreCase) are ignored. * - If you are generating your JavaScript from some other templating engine (not * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), * remember to escape your regular expression (and be aware that you might need more than * one level of escaping depending on your templating engine and the way you interpolated * the value.) Do make use of your platform's escaping mechanism as it might be good * enough before coding your own. E.g. Ruby has * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). * Javascript lacks a similar built in function for escaping. Take a look at Google * Closure library's [goog.string.regExpEscape(s)]( * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). * * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. * * ## Show me an example using SCE. * * * *

* * * * ## Can I disable SCE completely? * * Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits * for little coding overhead. It will be much harder to take an SCE disabled application and * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE * for cases where you have a lot of existing code that was written before SCE was introduced and * you're migrating them a module at a time. * * That said, here's how you can completely disable SCE: * * ``` * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) { * // Completely disable SCE. For demonstration purposes only! * // Do not use in new projects. * $sceProvider.enabled(false); * }); * ``` * */ function $SceProvider() { var enabled = true; /** * @ngdoc method * @name $sceProvider#enabled * @kind function * * @param {boolean=} value If provided, then enables/disables SCE. * @return {boolean} true if SCE is enabled, false otherwise. * * @description * Enables/disables SCE and returns the current value. */ this.enabled = function(value) { if (arguments.length) { enabled = !!value; } return enabled; }; /* Design notes on the default implementation for SCE. * * The API contract for the SCE delegate * ------------------------------------- * The SCE delegate object must provide the following 3 methods: * * - trustAs(contextEnum, value) * This method is used to tell the SCE service that the provided value is OK to use in the * contexts specified by contextEnum. It must return an object that will be accepted by * getTrusted() for a compatible contextEnum and return this value. * * - valueOf(value) * For values that were not produced by trustAs(), return them as is. For values that were * produced by trustAs(), return the corresponding input value to trustAs. Basically, if * trustAs is wrapping the given values into some type, this operation unwraps it when given * such a value. * * - getTrusted(contextEnum, value) * This function should return the a value that is safe to use in the context specified by * contextEnum or throw and exception otherwise. * * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be * opaque or wrapped in some holder object. That happens to be an implementation detail. For * instance, an implementation could maintain a registry of all trusted objects by context. In * such a case, trustAs() would return the same object that was passed in. getTrusted() would * return the same object passed in if it was found in the registry under a compatible context or * throw an exception otherwise. An implementation might only wrap values some of the time based * on some criteria. getTrusted() might return a value and not throw an exception for special * constants or objects even if not wrapped. All such implementations fulfill this contract. * * * A note on the inheritance model for SCE contexts * ------------------------------------------------ * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This * is purely an implementation details. * * The contract is simply this: * * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value) * will also succeed. * * Inheritance happens to capture this in a natural way. In some future, we * may not use inheritance anymore. That is OK because no code outside of * sce.js and sceSpecs.js would need to be aware of this detail. */ this.$get = ['$parse', '$sceDelegate', function( $parse, $sceDelegate) { // Prereq: Ensure that we're not running in IE<11 quirks mode.

However, the parsed components will not be set if the URL assigned did not specify * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)

For example `{name:"M", phone:"1"}` predicate will return an array of items * which have property `name` containing "M" and property `phone` containing "1". A special * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match * against any property of the object or its nested object properties. That's equivalent to the * simple substring match with a `string` as described above.

Primitive values are converted to strings. Objects are not compared against * primitives, unless they have a custom `toString` method (e.g. `Date` objects). * * * Defaults to `false`. * * @param {string} [anyPropertyKey] The special property name that matches against any property. * By default `$`. * * @example

The comparator function is used to sort the items, based on the derived values, types and * indices. * * If you use a custom comparator, it will be called with pairs of objects of the form * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the * second, or `1` otherwise. * * In order to ensure that the sorting will be deterministic across platforms, if none of the * specified predicates can distinguish between two items, `orderBy` will automatically introduce a * dummy predicate that returns the item's index as `value`. * (If you are using a custom comparator, make sure it can handle this predicate as well.) * * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted * value for an item, `orderBy` will try to convert that object to a primitive value, before passing * it to the comparator. The following rules govern the conversion: * * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be * used instead.
* (If the object has a `valueOf()` method that returns another object, then the returned object * will be used in subsequent steps.) * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that * returns a primitive, its return value will be used instead.
* (If the object has a `toString()` method that returns another object, then the returned object * will be used in subsequent steps.) * 3. No conversion; the object itself is used. * * ### The default comparator * * The default, built-in comparator should be sufficient for most usecases. In short, it compares * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to * using their index in the original collection, and sorts values of different types by type. * * More specifically, it follows these steps to determine the relative order of items: * * 1. If the compared values are of different types, compare the types themselves alphabetically. * 2. If both values are of type `string`, compare them alphabetically in a case- and * locale-insensitive way. * 3. If both values are objects, compare their indices instead. * 4. Otherwise, return: * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`). * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator). * - `1`, otherwise. * * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being * saved as numbers and not strings. * **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e. * `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to * other values. * * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort. * @param {(Function|string|Array.)=} expression - A predicate (or list of * predicates) to be used by the comparator to determine the order of elements. * * Can be one of: * * - `Function`: A getter function. This function will be called with each item as argument and * the return value will be used for sorting. * - `string`: An Angular expression. This expression will be evaluated against each item and the * result will be used for sorting. For example, use `'label'` to sort by a property called * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label` * property.
* (The result of a constant expression is interpreted as a property name to be used for * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a * property called `special name`.)
* An expression can be optionally prefixed with `+` or `-` to control the sorting direction, * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided, * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons. * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the * relative order of two items, the next predicate is used as a tie-breaker. * * **Note:** If the predicate is missing or empty then it defaults to `'+'`. * * @param {boolean=} reverse - If `true`, reverse the sorting order. * @param {(Function)=} comparator - The comparator function used to determine the relative order of * value pairs. If omitted, the built-in comparator will be used. * * @returns {Array} - The sorted array. * * * @example * ### Ordering a table with `ngRepeat` * * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means * it defaults to the built-in comparator. *

If specified, the form controller will be published into * related scope, under this name. * */ /** * @ngdoc directive * @name form * @restrict E * * @description * Directive that instantiates * {@link form.FormController FormController}. * * If the `name` attribute is specified, the form controller is published onto the current scope under * this name. * * # Alias: {@link ng.directive:ngForm `ngForm`} * * In Angular, forms can be nested. This means that the outer form is valid when all of the child * forms are valid as well. However, browsers do not allow nesting of `` elements, so * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group * of controls needs to be determined. * * # CSS classes * - `ng-valid` is set if the form is valid. * - `ng-invalid` is set if the form is invalid. * - `ng-pending` is set if the form is pending. * - `ng-pristine` is set if the form is pristine. * - `ng-dirty` is set if the form is dirty. * - `ng-submitted` is set if the form was submitted. * * Keep in mind that ngAnimate can detect each of these classes when added and removed. * * * # Submitting a form and preventing the default action * * Since the role of forms in client-side Angular applications is different than in classical * roundtrip apps, it is desirable for the browser not to translate the form submission into a full * page reload that sends the data to the server. Instead some javascript logic should be triggered * to handle the form submission in an application-specific way. * * For this reason, Angular prevents the default action (form submission to the server) unless the * `` element has an `action` attribute specified. * * You can use one of the following two ways to specify what javascript method should be called when * a form is submitted: * * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element * - {@link ng.directive:ngClick ngClick} directive on the first * button or input field of type submit (input[type=submit]) * * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} * or {@link ng.directive:ngClick ngClick} directives. * This is because of the following form submission rules in the HTML specification: * * - If a form has only one input field then hitting enter in this field triggers form submit * (`ngSubmit`) * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter * doesn't trigger submit * - if a form has one or more input fields and one or more buttons or input[type=submit] then * hitting enter in any of the input fields will trigger the click handler on the *first* button or * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) * * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` * to have access to the updated model. * * ## Animation Hooks * * Animations in ngForm are triggered when any of the associated CSS classes are added and removed. * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any * other validations that are performed within the form. Animations in ngForm are similar to how * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well * as JS animations. * * The following example shows a simple way to utilize CSS transitions to style a form element * that has been rendered as invalid after it has been validated: * *
 * //be sure to include ngAnimate as a module to hook into more
 * //advanced animations
 * .my-form {
 *   transition:0.5s linear all;
 *   background: white;
 * }
 * .my-form.ng-invalid {
 *   background: red;
 *   color:white;
 * }
 * 
* * @example userType: Required!
userType = {{userType}}
myForm.input.$valid = {{myForm.input.$valid}}
myForm.input.$error = {{myForm.input.$error}}
myForm.$valid = {{myForm.$valid}}

*

* In v1.5.9+, in order to avoid interfering with already existing, custom directives for * `input[range]`, you need to let Angular know that you want to enable its built-in support. * You can do this by adding the `ng-input-range` attribute to the input element. E.g.: * `` *


*

* Input elements without the `ng-input-range` attibute will continue to be treated the same * as in previous versions (e.g. their model value will be a string not a number and Angular * will not take `min`/`max`/`step` attributes and properties into account). *


*

* **Note:** From v1.6.x onwards, the support for `input[range]` will be always enabled and * the `ng-input-range` attribute will have no effect. *


*

* This documentation page refers to elements which have the built-in support enabled; i.e. * elements _with_ the `ng-input-range` attribute. *

*
* * The model for the range input must always be a `Number`. * * IE9 and other browsers that do not support the `range` type fall back * to a text input without any default values for `min`, `max` and `step`. Model binding, * validation and number parsing are nevertheless supported. * * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]` * in a way that never allows the input to hold an invalid value. That means: * - any non-numerical value is set to `(max + min) / 2`. * - any numerical value that is less than the current min val, or greater than the current max val * is set to the min / max val respectively. * - additionally, the current `step` is respected, so the nearest value that satisfies a step * is used. * * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range)) * for more info. * * This has the following consequences for Angular: * * Since the element value should always reflect the current model value, a range input * will set the bound ngModel expression to the value that the browser has set for the * input element. For example, in the following input ``, * if the application sets `model.value = null`, the browser will set the input to `'50'`. * Angular will then set the model to `50`, to prevent input and model value being out of sync. * * That means the model for range will immediately be set to `50` after `ngModel` has been * initialized. It also means a range input can never have the required error. * * This does not only affect changes to the model value, but also to the values of the `min`, * `max`, and `step` attributes. When these change in a way that will cause the browser to modify * the input value, Angular will also update the model value. * * Automatic value adjustment also means that a range input element can never have the `required`, * `min`, or `max` errors. * * However, `step` is currently only fully implemented by Firefox. Other browsers have problems * when the step value changes dynamically - they do not adjust the element value correctly, but * instead may set the `stepMismatch` error. If that's the case, the Angular will set the `step` * error on the input, and set the model to `undefined`. * * Note that `input[range]` is not compatible with `ngMax`, `ngMin`, and `ngStep`, because they do * not set the `min` and `max` attributes, which means that the browser won't automatically adjust * the input value based on their values, and will always assume min = 0, max = 100, and step = 1. * * @param ngInputRange The presense of this attribute enables the built-in support for * `input[range]`. * @param {string} ngModel Assignable angular expression to data-bind to. * @param {string=} name Property name of the form under which the control is published. * @param {string=} min Sets the `min` validation to ensure that the value entered is greater * than `min`. Can be interpolated. * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`. * Can be interpolated. * @param {string=} step Sets the `step` validation to ensure that the value entered matches the `step` * Can be interpolated. * @param {string=} ngChange Angular expression to be executed when the ngModel value changes due * to user interaction with the input element. * @param {expression=} ngChecked If the expression is truthy, then the `checked` attribute will be set on the * element. **Note** : `ngChecked` should not be used alongside `ngModel`. * Checkout {@link ng.directive:ngChecked ngChecked} for usage. * * @example

Notice how different directives (`contenteditable`, `ng-model`, and `required`) * collaborate together to achieve the desired result. * * `contenteditable` is an HTML5 attribute, which tells the browser to let the element * contents be edited in place by the user. * * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize} * module to automatically remove "bad" content like inline event listener (e.g. ``). * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks * that content using the `$sce` service. * * [contenteditable] { border: 1px solid black; background-color: white; min-height: 20px; } .ng-invalid { border: 1px solid red; } angular.module('customControl', ['ngSanitize']). directive('contenteditable', ['$sce', function($sce) { return { restrict: 'A', // only activate on element attribute require: '?ngModel', // get a hold of NgModelController link: function(scope, element, attrs, ngModel) { if (!ngModel) return; // do nothing if no ng-model // Specify how UI should be updated ngModel.$render = function() { element.html($sce.getTrustedHtml(ngModel.$viewValue || '')); }; // Listen for change events to enable binding element.on('blur keyup change', function() { scope.$evalAsync(read); }); read(); // initialize // Write data to the model function read() { var html = element.html(); // When we clear the content editable the browser leaves a

    *
  1. Type something in the input. You will see that the model is not yet updated
  2. *
  3. Press the Escape key. *

    1. In the first example, nothing happens, because the model is already '', and no * update is detected. If you blur the input, the model will be set to the current view. *

If there are no special {@link ngModelOptions} specified then the staged * value sent directly for processing, finally to be applied to `$modelValue` and then the * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners, * in the `$viewChangeListeners` list, are called. * * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn` * and the `default` trigger is not listed, all those actions will remain pending until one of the * `updateOn` events is triggered on the DOM element. * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions} * directive is used with a custom debounce for this particular event. * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce` * is specified, once the timer runs out. * * When used with standard inputs, the view value will always be a string (which is in some cases * parsed into another type, such as a `Date` object for `input[date]`.) * However, custom controls might also pass objects to this method.

If you only change * the property of the object then ngModel will not realize that the object has changed and * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should * not change properties of the copy once it has been passed to `$setViewValue`. * Otherwise you may cause the model value on the scope to change incorrectly. * *
* In any case, the value passed to the method should always reflect the current value * of the control. For example, if you are calling `$setViewValue` for an input element, * you should pass the input DOM value. Otherwise, the control and the scope model become * out of sync.

This is important to know when * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the * object or collection change, `ngModel` will not be notified and so the input will not be re-rendered. * * The model must be assigned an entirely new object or collection before a re-rendering will occur. * * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or * if the select is given the `multiple` attribute. * * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the * first level of the object (or only changing the properties of an item in the collection if it's an array) will still * not trigger a re-rendering of the model. * * # CSS classes * The following CSS classes are added and removed on the associated input/select/textarea element * depending on the validity of the model. * * - `ng-valid`: the model is valid * - `ng-invalid`: the model is invalid * - `ng-valid-[key]`: for each valid key added by `$setValidity` * - `ng-invalid-[key]`: for each invalid key added by `$setValidity` * - `ng-pristine`: the control hasn't been interacted with yet * - `ng-dirty`: the control has been interacted with * - `ng-touched`: the control has been blurred * - `ng-untouched`: the control hasn't been blurred * - `ng-pending`: any `$asyncValidators` are unfulfilled * - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined * by the {@link ngModel.NgModelController#$isEmpty} method * - `ng-not-empty`: the view contains a non-empty value * * Keep in mind that ngAnimate can detect each of these classes when added and removed. * * ## Animation Hooks * * Animations within models are triggered when any of the associated CSS classes are added and removed * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`, * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself. * The animations that are triggered within ngModel are similar to how they work in ngClass and * animations can be hooked into using CSS transitions, keyframes as well as JS animations. * * The following example shows a simple way to utilize CSS transitions to style an input element * that has been rendered as invalid after it has been validated: * *
 * //be sure to include ngAnimate as a module to hook into more
 * //advanced animations
 * .my-input {
 *   transition:0.5s linear all;
 *   background: white;
 * }
 * .my-input.ng-invalid {
 *   background: red;
 *   color:white;
 * }
 * 
* * @example *

Update input to see transitions when valid/invalid. Integer is a valid value.

*
* * ## Binding to a getter/setter * * Sometimes it's helpful to bind `ngModel` to a getter/setter function. A getter/setter is a * function that returns a representation of the model when called with zero arguments, and sets * the internal state of a model when called with an argument. It's sometimes useful to use this * for models that have an internal representation that's different from what the model exposes * to the view. * *
* **Best Practice:** It's best to keep getters fast because Angular is likely to call them more * frequently than other parts of your code. *
* * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to * a `
`, which will enable this behavior for all ``s within it. See * {@link ng.directive:ngModelOptions `ngModelOptions`} for more. * * The following example shows how to use `ngModel` with a getter/setter: * * @example *
user.name = 
angular.module('getterSetterExample', []) .controller('ExampleController', ['$scope', function($scope) { var _name = 'Brian'; $scope.user = { name: function(newName) { // Note that newName can be undefined for two reasons: // 1. Because it is called as a getter and thus called with no arguments // 2. Because the property should actually be set to undefined. This happens e.g. if the // input is invalid return arguments.length ? (_name = newName) : _name; } }; }]); *

A * value of 0 triggers an immediate update. If an object is supplied instead, you can specify a * custom value for each event. For example: * `ng-model-options="{ updateOn: 'default blur', debounce: { 'default': 500, 'blur': 0 } }"` * - `allowInvalid`: boolean value which indicates that the model can be set with values that did * not validate correctly instead of the default behavior of setting the model to undefined. * - `getterSetter`: boolean value which determines whether or not to treat functions bound to `ngModel` as getters/setters. * - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for * ``, ``, ... . It understands UTC/GMT and the * continental US time zone abbreviations, but for general use, use a time zone offset, for * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian) * If not specified, the timezone of the browser will be used. * * @example The following example shows how to override immediate updates. Changes on the inputs within the form will update the model only when the control loses focus (blur event). If `escape` key is pressed while the input field is focused, the value is reset to the value in the current model.

* Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}. * This may be useful when, for instance, nesting ngRepeats. *
* * * # Iterating over object properties * * It is possible to get `ngRepeat` to iterate over the properties of an object using the following * syntax: * * ```js *
...
* ``` * * However, there are a few limitations compared to array iteration: * * - The JavaScript specification does not define the order of keys * returned for an object, so Angular relies on the order returned by the browser * when running `for key in myObj`. Browsers generally follow the strategy of providing * keys in the order in which they were defined, although there are exceptions when keys are deleted * and reinstated. See the * [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes). * * - `ngRepeat` will silently *ignore* object keys starting with `$`, because * it's a prefix used by Angular for public (`$`) and private (`$$`) properties. * * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with * objects, and will throw an error if used with one. * * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter) * or implement a `$watch` on the object yourself. * * * # Tracking and Duplicates * * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM: * * * When an item is added, a new instance of the template is added to the DOM. * * When an item is removed, its template instance is removed from the DOM. * * When items are reordered, their respective templates are reordered in the DOM. * * To minimize creation of DOM elements, `ngRepeat` uses a function * to "keep track" of all items in the collection and their corresponding DOM elements. * For example, if an item is added to the collection, `ngRepeat` will know that all other items * already have DOM elements, and will not re-render them. * * The default tracking function (which tracks items by their identity) does not allow * duplicate items in arrays. This is because when there are duplicates, it is not possible * to maintain a one-to-one mapping between collection items and DOM elements. * * If you do need to repeat duplicate items, you can substitute the default tracking behavior * with your own using the `track by` expression. * * For example, you may track items by the index of each item in the collection, using the * special scope property `$index`: * ```html *
* {{n}} *
* ``` * * You may also use arbitrary expressions in `track by`, including references to custom functions * on the scope: * ```html *
* {{n}} *
* ``` * *
* If you are working with objects that have a unique identifier property, you should track * by this identifier instead of the object instance. Should you reload your data later, `ngRepeat` * will not have to rebuild the DOM elements for items it has already rendered, even if the * JavaScript objects in the collection have been substituted for new ones. For large collections, * this significantly improves rendering performance. If you don't have a unique identifier, * `track by $index` can also provide a performance boost. *
* * ```html *
* {{model.name}} *
* ``` * *
*
* Avoid using `track by $index` when the repeated template contains * {@link guide/expression#one-time-binding one-time bindings}. In such cases, the `nth` DOM * element will always be matched with the `nth` item of the array, so the bindings on that element * will not be updated even when the corresponding item changes, essentially causing the view to get * out-of-sync with the underlying data. *
* * When no `track by` expression is provided, it is equivalent to tracking by the built-in * `$id` function, which tracks items by their identity: * ```html *
* {{obj.prop}} *
* ``` * *
*
* **Note:** `track by` must always be the last expression: *
* ``` *
* {{model.name}} *
* ``` * * * # Special repeat start and end points * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively. * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on) * up to and including the ending HTML tag where **ng-repeat-end** is placed. * * The example below makes use of this feature: * ```html *
* Header {{ item }} *
*
* Body {{ item }} *
*
* Footer {{ item }} *
* ``` * * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to: * ```html *
* Header A *
*
* Body A *
*
* Footer A *
*
* Header B *
*
* Body B *
*
* Footer B *
* ``` * * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**). * * @animations * | Animation | Occurs | * |----------------------------------|-------------------------------------| * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter | * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out | * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered | * * See the example below for defining CSS animations with ngRepeat. * * @element ANY * @scope * @priority 1000 * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These * formats are currently supported: * * * `variable in expression` – where variable is the user defined loop variable and `expression` * is a scope expression giving the collection to enumerate. * * For example: `album in artist.albums`. * * * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers, * and `expression` is the scope expression giving the collection to enumerate. * * For example: `(name, age) in {'adam':10, 'amalie':12}`. * * * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression * which can be used to associate the objects in the collection with the DOM elements. If no tracking expression * is specified, ng-repeat associates elements by identity. It is an error to have * more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are * mapped to the same DOM element, which is not possible.) * * Note that the tracking expression must come last, after any filters, and the alias expression. * * For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements * will be associated by item identity in the array. * * For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique * `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements * with the corresponding item in the array by identity. Moving the same object in array would move the DOM * element in the same way in the DOM. * * For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this * case the object identity does not matter. Two objects are considered equivalent as long as their `id` * property is same. * * For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter * to items in conjunction with a tracking expression. * * * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the * intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message * when a filter is active on the repeater, but the filtered result set is empty. * * For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after * the items have been processed through the filter. * * Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end * (and not as operator, inside an expression). * * For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` . * * @example * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed * results by name or by age. New (entering) and removed (leaving) items are animated.

It is possible to associate multiple values to * the same `ngSwitchWhen` by defining the optional attribute * `ngSwitchWhenSeparator`.
