Issue about AngularJS executing controller twice

Note that you can also attach controllers to the DOM by declaring it in a route definition via the $route service. A common mistake is to declare the controller again using ng-controller in the template itself. This will cause the controller to be attached and executed twice.
When you use ngRoute with the ng-view directive, the controller gets attached to that dom element by default. So you will not need to attach it again in the template.

When you use ngRoute with the ng-view directive, the controller gets attached to that dom element by default. So you will not need to attach it again in the template.

今天做AngularJS路由的时候遇到了一个问题,controller里面的方法执行了两次,后来google时发现了原因,大意是:

//路由里面已经绑定了一次controller
.when('/repo-top', {
    templateUrl: 'views/repo-top.html',
    controller: 'RepoTopCtrl'
})

//在模板上面不需要再次绑定了
//<div ng-controller="RepoTopCtrl">custom content</div>
<div>custom content</div>
