This is a key aspect of how angular + * supports the principles behind the Model-View-Controller design pattern. + * + * MVC components in angular: + * + * * Model — The Model is data in scope properties; scopes are attached to the DOM. + * * View — The template (HTML with data bindings) is rendered into the View. + * * Controller — The `ng-controller` directive specifies a Controller class; the class has + * methods that typically express the business logic behind the application. + * + * Note that an alternative way to define controllers is via the `{@link angular.module.ng.$route}` + * service. + * + * @element ANY + * @scope + * @param {expression} ng-controller Name of a globally accessible constructor function or an + * {@link guide/dev_guide.expressions expression} that on the current scope evaluates to a + * constructor function. + * + * @example + * Here is a simple form for editing user contact information. Adding, removing, clearing, and + * greeting are methods declared on the controller (see source tab). These methods can + * easily be called from the angular markup. Notice that the scope becomes the `this` for the + * controller's instance. This allows for easy access to the view data from the controller. Also + * notice that any changes to the data are automatically reflected in the View without the need + * for a manual update. + <doc:example> + <doc:source> + <script type="text/javascript"> + function SettingsController($scope) { + $scope.name = "John Smith"; + $scope.contacts = [ + {type:'phone', value:'408 555 1212'}, + {type:'email', value:'john.smith@example.org'} ]; + + $scope.greet = function() { + alert(this.name); + }; + + $scope.addContact = function() { + this.contacts.push({type:'email', value:'yourname@example.org'}); + }; + + $scope.removeContact = function(contactToRemove) { + var index = this.contacts.indexOf(contactToRemove); + this.contacts.splice(index, 1); + }; + + $scope.clearContact = function(contact) { + contact.type = 'phone'; + contact.value = ''; + }; + } + </script> + <div ng-controller="SettingsController"> + Name: <input type="text" ng-model="name"/> + [ <a href="" ng-click="greet()">greet</a> ]<br/> + Contact: + <ul> + <li ng-repeat="contact in contacts"> + <select ng-model="contact.type"> + <option>phone</option> + <option>email</option> + </select> + <input type="text" ng-model="contact.value"/> + [ <a href="" ng-click="clearContact(contact)">clear</a> + | <a href="" ng-click="removeContact(contact)">X</a> ] + </li> + <li>[ <a href="" ng-click="addContact()">add</a> ]</li> + </ul> + </div> + </doc:source> + <doc:scenario> + it('should check controller', function() { + expect(element('.doc-example-live div>:input').val()).toBe('John Smith'); + expect(element('.doc-example-live li:nth-child(1) input').val()) + .toBe('408 555 1212'); + expect(element('.doc-example-live li:nth-child(2) input').val()) + .toBe('john.smith@example.org'); + + element('.doc-example-live li:first a:contains("clear")').click(); + expect(element('.doc-example-live li:first input').val()).toBe(''); + + element('.doc-example-live li:last a:contains("add")').click(); + expect(element('.doc-example-live li:nth-child(3) input').val()) + .toBe('yourname@example.org'); + }); + </doc:scenario> + </doc:example> + */ +var ngControllerDirective = [function() { + return { + scope: true, + controller: '@' + }; +}]; |
