接入元件

Question

我具有控制器的功能如下

function UserDetailsControl($scope, $routeParams, UserService) { 
    $scope.user = UserService.get({id: $routeParams.id}); 
    alert($scope.user.phone); 
} 

當我在模板訪問用戶變量它看起來像這樣：

{ 
    "website_name": null, 
    "email": "Monroe@Chamorro.com", 
    "first_name": "Monroe", 
    "id": "31", 
    "last_name": "Chamorro", 
    "phone": 2147483647, 
} 

但alert($scope.user.phone);這總是返回undefined 。爲什麼？無論我嘗試訪問哪個元素，始終返回undefined。

這是因爲$資源是異步的。檢查此線程以獲得詳細的擴展：How does the $resource `get` function work synchronously in AngularJS?
