angularjs控制器执行两次 [英] angularjs controller executes twice

问题描述

有一个类似的问题被问<一个href=\"http://stackoverflow.com/questions/15535336/combating-angularjs-executing-controller-twice\">here但它并没有帮助我。

我学习angularjs，我注意到控制器执行两次。

我有一个非常简单的例子小提琴，显示了行为 rel=\"nofollow\">

我建的例子，因为我是学习服务，起初我还以为是服务到控制器的注入，但我评论所有相关的服务和仍然控制器的执行两次code

我的例子的作品，但我怕我做错了什么。

 ＆LT; D​​IV NG-应用=MyApp的＆GT;
  ＆LT; D​​IV NG控制器=MyCtrl＆GT;
    {{数据1}}
  ＆LT; / DIV＆GT;
＆LT; / DIV＆GT;VAR应用= angular.module（'MyApp的'，[]）
app.service（'服务1'，函数（）{
  返回{
    ajxResponse1：dataFromService1
  };
 }）;功能MyCtrl（$范围，服务1）{
  警报（'进入MyCtrl'）;
  $ scope.data1 = Service1.ajxResponse1;
  警报（'退出MyCtrl'）;
}
 

解决方案

一个可能的来源是这样的：如果你正在使用路由和指定路线控制器 - 你不能在该路由使用模板指定。我们有这样的问题，当这个被忽略。

A similar question was asked here but it did not help me.

I am learning angularjs and I noticed the controller is executed twice.

I have a very simple fiddle example that shows the behavior here

I built the example as I was learning about services and at first I thought it was the injecting of the services into the controller but I commented all the code related to the services and still the controller is executed twice.

My example works but I am afraid I am doing something wrong.

<div ng-app="MyApp">
  <div ng-controller="MyCtrl">
    {{data1}} 
  </div>
</div>

var app = angular.module('MyApp', [])
app.service('Service1', function(){
  return {
    ajxResponse1: 'dataFromService1'
  };
 });

function MyCtrl($scope, Service1){
  alert('Entering MyCtrl');
  $scope.data1 = Service1.ajxResponse1;    
  alert('Exiting MyCtrl');
}

解决方案

One possible source is this: if you are using Routing and specify the controller in routes - you must not specify it in template that the route uses. We had that problem when this was overlooked.
