Angularjs - 更新同一个控制器的多个实例 [英] Angularjs - Updating multiple instances of the same controller

问题描述

我的问题：我有多个实例在我的网站控制器。当我更新'X'，只有当前实例/ DIV得到更新。

My problem: I have multiple instances a controller in my site. When I update 'x', only the current instance/div gets updated.

的jsfiddle： http://jsfiddle.net/evgahe2u/ （简化例如，每个NG-控制器在自己的看法。）

JSFiddle: http://jsfiddle.net/evgahe2u/ (simplified example, each ng-controller is in its own view.)

HTML

<!-- this is a simplified example -->
<div ng-app="myApp">
       <!-- this is in view1.html -->
        <div ng-controller="myController">
                <input type="text" ng-model="x" /> {{x}}
        </div>
        <!-- this is in view2.html -->
        <div ng-controller="myController">
                <input type="text" ng-model="x" /> {{x}}
        </div>
</div>

JS

var myApp = angular.module('myApp', []);
myApp.controller('myController', function($scope) {
    $scope.x = 'test';
});

我的问题：我怎么能有这么当我更新View1.html的X值，它会再更新view2.html的看法

My question: How can I have it so when I update View1.html's X value, it will then update view2.html's view?

推荐答案

这是pretty容易。

That's pretty easy.

据我做到这一点的最好办法是创建一个工厂。

According to me the best way to do this is to create a factory.

比方说，工厂X和让我们创建两个控制器为两种观点：

Let's say factory X and let's create two controllers for both views:

myApp.controller('1Ctrl', function($scope, x) {
  $scope.x = x.x;
});

myApp.controller('2Ctrl', function($scope, x) {
  $scope.x = x.x;
});

myApp.factory('x', function() {
  return {
    x: 'value'
  };
});

完整的例子：的jsfiddle

现在如果X被更新，将在两个控制器更新，因为对象的属性。在两个范围都x'es都是相同的x。

Now if X is updated it will update in both controllers, because of the properties of an object. Both x'es on both scopes are the same x.
