Angularjs在兩個模塊之間共享數據

我試圖在兩個不同模塊中的兩個控制器之間共享一個服務。我見過的帖子讓我相信我在正確的軌道上，here和here。但我顯然錯過了一些東西。這是我的代碼和codepen。Angularjs在兩個模塊之間共享數據

該索引正在設置好，但是isSidebarActive不會像所期望的那樣被自動觸發。任何幫助將非常感激。謝謝！

index.js

angular 
    .module('app', ['app.layout', 'app.sidebar']); 
angular 
    .module('app.layout', []) 
    .service('layoutService', function() { 
     var vm = this; 
     var sidebarStatus = null; 
     vm.isSidebarActive = function() { 
      console.log('isSidebarActive: ' + (sidebarStatus ? 'true' : 'false')); 
      return sidebarStatus; 
     }; 
     vm.setSidebarStatus = function(status) { 
      console.log('setSidebarStatus: ' + (status ? 'true' : 'false')); 
      sidebarStatus = status; 
     }; 
    }) 
    .controller('ShellController', ['layoutService', function(layoutService) { 
     var vm = this; 
     vm.isSidebarActive = function() { 
      return layoutService.isSidebarActive(); 
     } 
    }]); 

angular 
    .module('app.sidebar', ['app.layout']) 
    .controller('SidebarController', ['layoutService', function(layoutService) { 
     var vm = this; 
     var index = null; 
     vm.setIndex = function(i) { 
      index = i; 
      layoutService.setSidebarStatus(i > 0); 
      console.log('setIndex: ' + index); 
     }; 
     vm.isIndex = function (i) { 
      return index === i; 
     }; 
    }]);

的index.html

<body ng-app="app"> 
    <div ng-controller="ShellController as shell"> 
    <div class="alert alert-info" ng-show="shell.isSidebarActive">active</div> 
    <div class="alert alert-warning" ng-hide="shell.isSidebarActive">non-active</div> 
    <div/> 
    <div ng-controller="SidebarController as sidebar"> 
    <a class="btn" ng-click="sidebar.setIndex(1)">active</a> 
    <a class="btn" ng-click="sidebar.setIndex(0)">non-active</a> 
    <div/> 
</body>

試試這個：

<body ng-app="app"> 
     <div ng-controller="ShellController as shell"> 
     <div class="alert alert-info" ng-show="shell.isSidebarActive()">active</div> 
     <div class="alert alert-warning" ng-hide="shell.isSidebarActive()">non-active</div> 
     <div/> 
     <div ng-controller="SidebarController as sidebar"> 
     <a class="btn" ng-click="sidebar.setIndex(1)">active</a> 
     <a class="btn" ng-click="sidebar.setIndex(0)">non-active</a> 
     <div/> 
    </body>

必須調用函數shell.isSidebarActive()在ng-show和ng-hide http://codepen.io/anon/pen/EjpeoR

從第二個模塊中刪除數組。 – Ved

謝謝你，我花了很長時間才弄清楚。 – user3009902
