copied!<p><a href="http://jsfiddle.net/VP4d5/2/" rel="noreferrer">http://jsfiddle.net/VP4d5/2/</a></p> <p>Here's an updated fiddle. Basically if you're going to share the same data object between two controllers from a service you just need to use an object of some sort aside from a string or javascript primitive. In this case I'm just using a regular Object {} to share the data between the two controllers.</p> <p>The JS</p> <pre><code>angular.module('myApp', []) .controller('Ctrl1', function ($scope, App) { $scope.localData1 = App.data; }) .controller('Ctrl2', function ($scope, App) { $scope.localData2 = App.data; }) .service('App', function () { this.data = {status:'Good'}; }); </code></pre> <p>The HTML</p> <pre><code><div ng-controller="Ctrl1"> <div> Ctrl1 Status is: {{status}} </div> <div> <input type="text" ng-model="localData1.status" /> </div> <div ng-controller="Ctrl2">Ctrl2 Status is: {{status}} <div> <input type="text" ng-model="localData2.status" /> </div> </div> </code></pre> <p>Nothing wrong with using a service here but if the only purpose is to have a shared object across the app then I think using .value makes a bit more sense. If this service will have functions for interacting with endpoints and the data be sure to use angular.copy to update the object properties instead of using = which will replace the service's local reference but won't be reflected in the controllers.</p> <p><a href="http://jsfiddle.net/VP4d5/3/" rel="noreferrer">http://jsfiddle.net/VP4d5/3/</a></p> <p>The modified JS using .value</p> <pre><code>angular.module('myApp', []) .controller('Ctrl1', function ($scope, sharedObject) { $scope.localData1 = sharedObject; }) .controller('Ctrl2', function ($scope, sharedObject) { $scope.localData2 = sharedObject; }) .value("sharedObject", {status:'Awesome'}); </code></pre>
