我怎样才能从一个控制器的一些数据传递给另一个对等控制器 [英] How can I pass some data from one controller to another peer controller

问题描述

我有以下两个对等控制器。有没有父母这些：

I have the following two peer controllers. There's no parent to these:

<div data-ng-controller="Controller1">

</div>

<div data-ng-controller="Controller2">
   The value of xxx is: {{ xxx }}
</div>

angular.module('test')
   .controller('QuestionsStatusController1',
    ['$rootScope', '$scope'
    function ($rootScope, $scope) {
    // How can I set the value of xxx in the HTML that's part of Controller2    
    }]);

angular.module('test')
   .controller('QuestionsStatusController2',
    ['$rootScope', '$scope',
    function ($rootScope, $scope) {
    }]);

在控制器1我想更新该是由控制器2控制的HTML变量XXX的值。有没有一种方法可以让我做到这一点？

In controller 1 I want to update the value of the variable xxx in the HTML that's controlled by Controller2. Is there a way I can do this?

推荐答案

绝对使用服务控制器之间共享数据，这里是一个工作的例子。
$广播是不可去，你应该避免使用事件系统时，有一个更合适的方式的方式。使用服务，价值或不变（全局常量）。

Definitely use a service to share data between controllers, here is a working example. $broadcast is not the way to go, you should avoid using the eventing system when there is a more appropriate way. Use a 'service', 'value' or 'constant' (for global constants).

下面是一个输入一个例子，所以你可以看到页面上的数据镜像：

Here is an example with an input so you can see the data mirror on the page: http://plnkr.co/edit/DbBp60AgfbmGpgvwtnpU

var testModule = angular.module('testmodule', []);

testModule
   .controller('QuestionsStatusController1',
    ['$rootScope', '$scope', 'myservice',
    function ($rootScope, $scope, myservice) {
       $scope.myservice = myservice;   
    }]);

testModule
   .controller('QuestionsStatusController2',
    ['$rootScope', '$scope', 'myservice',
    function ($rootScope, $scope, myservice) {
      $scope.myservice = myservice;
    }]);

testModule
    .service('myservice', function() {
      this.xxx = "yyy";
    });
