问题描述
在阅读了api和开发人员指南之后，我仍然不理解通过在给定路径中声明'controller'而提供的功能.现在，在我的视图中，我只是将我的控制器声明为ng-controller指令. ngRoute是否只是提供替代方法?
After reading both the api and the developer guide, I still don't understand the functionality provided by declaring 'controller' in a given route. Right now I just have my controllers declared as ng-controller directives in my views. Is ngRoute simply providing an alternative method?
要在代码中明确说明我的问题，请参见以下内容:
To make my question explicit in code, see below:
--Index.html
...
<body ng-app="MyApp">
<div ng-view>
</div>
</body>
--View.html
<div id="myView" ng-controller="MyController">
...
</div>
--Route.js
var app = angular.module('MyApp', [ require('angular-route') ]);
app.controller('MyController', ['$scope', function ($scope) {
console.log('this gets executed as I would expect');
}])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/', { templateUrl: '/Index.html' })
.when('/view', { templateUrl: '/View.html' });
// below line makes no difference as an alternative to above
//.when('/view', { templateUrl: '/View.html', controller: 'MyController' });
}]);
推荐答案
有两种方法为视图定义控制器.
There are two ways to define controller for a view.
- 在ng-route的控制器声明中要么
- 在ng-controller中查看.
任何一个都可以.
