我在学习angular.js，并想知道什么时候应该使用app.controller(“MyCtrl”，…)，当使用函数MyCtrl($ scope){…}时。
我看到在这个例子中的两种方法没有大的区别(link to a plunker)：
index.html：
@H_403_5@<body ng-app="myApp"> <div ng-controller="FirstCtrl as app1"> <button class="btn" ng-model="app1.count" ng-click="app1.increment()"> Click to increment</button> {{ app1.count }} </div> <div ng-controller="SecondCtrl"> <button class="btn" ng-model="count" ng-click="increment()"> Click to increment</button> {{ count }} </div> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.2/angular.js"></script> <script type="text/javascript" src="example.js"></script> </body>example.js：
@H_403_5@var app = angular.module("myApp",[]); app.controller("FirstCtrl",function () { this.count = 0; this.increment = function (){ this.count = this.count + 1; } }); function SecondCtrl($scope){ $scope.count = 0; $scope.increment = function (){ $scope.count = $scope.count + 1; } }
