如何将一些数据从一个控制器传递到另一个对等控制器 [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.这些没有父级:

<div data-ng-controller="Controller2">xxx 的值为:{{ xxx }}

angular.module('测试').controller('QuestionsStatusController1',['$rootScope', '$scope'函数($rootScope，$scope){//如何在属于 Controller2 的 HTML 中设置 xxx 的值}]);angular.module('测试').controller('QuestionsStatusController2',['$rootScope', '$scope',函数($rootScope，$scope){}]);

在控制器 1 中，我想更新由控制器 2 控制的 HTML 中变量 xxx 的值.有没有办法做到这一点?

解决方案

绝对使用服务在控制器之间共享数据，这里是一个工作示例.$broadcast 不是要走的路，当有更合适的方法时，您应该避免使用事件系统.使用服务"、值"或常量"(用于全局常量).

这是一个带有输入的示例，因此您可以在页面上看到数据镜像:http://plnkr.co/edit/DbBp60AgfbmGpgvwtnpU

var testModule = angular.module('testmodule', []);测试模块.controller('QuestionsStatusController1',['$rootScope', '$scope', 'myservice',功能($rootScope，$scope，myservice){$scope.myservice = myservice;}]);测试模块.controller('QuestionsStatusController2',['$rootScope', '$scope', 'myservice',功能($rootScope，$scope，myservice){$scope.myservice = myservice;}]);测试模块.service('myservice', function() {this.xxx = "yyy";});

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) {
    }]);

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?

解决方案

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).

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";
    });
