问题描述
我浏览了AngularJS网站上的教程，并注意到在
I worked through the tutorial on the AngularJS website and I noticed that in at step 7, they change how a controller is introduced into the application. Initially, they use a directive:
<body ng-controller="PhoneListCtrl">
...
</body>
但是，稍后将其更改为使用controller属性作为ng-route的一部分.
However, it later gets changed to use a controller attribute as part of an ng-route.
$routeProvider.
when('/phones', {
templateUrl: 'partials/phone-list.html',
controller: 'PhoneListCtrl'
}).
/* rest of routes here */
在此处进行更改的 git diff .这两种技术之间有区别吗?
Here's the git diff where the change is made. Is there a difference between these two techniques?
推荐答案
使用 ng-controller 指令的控制器:
- 在
ng-controller元素上创建了一个新的$ scope. - 显式视图与控制器的连接
- 与检查元素等可见
- A new $scope is created on
ng-controllerelement. - Explicit view-to-controller connection
- Visible with inspect element, etc
路线中的控制器:
- 在
ng-view元素上为每个路由创建一个新的$ scope. - 控制器可以请求在路由解析中定义的依赖项.
- 可选的视图到控制器连接.建议使用命名约定，以将到控制器的路由映射到视图.
- A new $scope is created per route on the
ng-viewelement. - The controller can request dependencies defined in the route resolve.
- Optional view-to-controller connection. Recommended to have a naming convention that maps routes to controllers to views.
