我使用兩個控制器和一個工廠服務來從中獲取數據。我想通過輸入'ng-model'過濾第二個控制器中的數據。所以我已經在兩個控制器中編寫了輸入ng-model(檢查index.html)。它的工作,如果我試圖在第二個控制器輸入字段中輸入輸入數據,但它不工作,如果我嘗試從第一個控制器輸入ng-app過濾。AngularJs過濾數據在另一個控制器

的index.html

使用服務,而不是一個工廠,如果你想分享的控制器之間的數據。服務是單身人士,工廠總是新的實例 – 23tux

控制器使用原型繼承共享範圍。所以,你需要確保你想要繼承的對象是一個實際的對象,以便引用保持綁定。如果試圖從範圍中共享一個原語,它們將不會被正確綁定,並且每個控制器都會最終生成它自己的副本。

這可能會在開始時正確繼承,但只要您更改子級的scope.number的值,綁定就會斷開連接。

-ParentController 
    -scope.number = 4 
    -ChildController 
    -scope.number //will not stay binded to parent's scope 

這對otherhand,如果你創建的範圍對象,將繼承對象的引用,在孩子控制器將保持綁定。

-ParentController 
    -scope.myObject.number = 4 
    -ChildController 
    -scope.myObject.number //will stay binded to parent's scope 

這是一個更好的解釋:Why don't the AngularJS docs use a dot in the model directive?

我已經將孩子控制器移動到父控制器,它的工作,謝謝。 – Bharath
