基本上我的問題是，我有一個AngularJS視圖（home.html），其中包含一個雙括號中的變量，如下所示：{{message}}
當$ scope.message變量被修改時，不更新，雖然它應該？我已經嘗試添加$ scope。$ apply（），導致沿着'正在進行的操作'的行發生異常
請檢查下面的代碼。在MainCtrl中調用$ scope.doLogin時，home.html中的{{message}}部分未被更新，即使我已將$ scope.message設置爲該函數中的新值。
任何幫助非常感謝，如果需要任何進一步的信息，請詢問。

所有的視圖都使用自己的'MainCtrl'並有自己的'$ scope'，所以當你從登錄表單調用'doLogin'時，它只會更新它自己範圍內的'message'，而不是控制器'ng-view'。 – user2718281
嗨，所以我想要做的是不可能的？或者你建議的解決方案是什麼。我感謝你的迴應btw謝謝:) –
請參閱[Angular：控制器之間共享數據]（http://stackoverflow.com/questions/21919962/angular-share-data-between-controllers）。簡而言之，從工廠返回一個對象並在控制器中處理該對象。讓我們知道它是否沒有幫助。 – user2718281
