角度對象如何獲取另一個對象的值

Question

如何使對象繼承其他對象的所有屬性。

這是代碼：

this.makeReady = function(order) { 
    var tempOrder = angular.copy(order); 
    tempOrder.status = 1; 
    angular.forEach(tempOrder.items, function(item){ 
     item.status = 1; 
    }) 
    return $http.put('/rest/change/invoice/'+order.id+'/', tempOrder).success(function(){ 
     order = tempOrder; // this doesn't work 
    }); 
} 

在成功的情況下：改變該對象的值。

Answer 1

嘗試在你的$scope.allOrders直接編輯的順序，看看是否能得到您的行爲你正在尋找。

this.makeReady = function (order) { 
     var tempOrder = angular.copy(order); 
     var orderIndex = $scope.allOrders.indexOf(order); 
     tempOrder.status = 1; 

     angular.forEach(tempOrder.items, function(item) { 
      item.status = 1; 
     }); 

     return $http.put('/rest/change/invoice/' + order.id + '/', tempOrder).success(function() { 
      $scope.allOrders[orderIndex] = tempOrder; 
     }); 
    } 

Answer 2

使用本

this.makeReady = function(order) { 
    var tempOrder = angular.copy(order); 
    tempOrder.status = 1; 
    angular.forEach(tempOrder.items, function(item){ 
     item.status = 1; 
    }) 
    $http.put('/rest/change/invoice/'+order.id+'/', tempOrder).success(function(){ 
     order = tempOrder; // this doesn't work 
     return order; 
    }); 
} 

或使用回叫功能

this.makeReady = function(order, callback) { 
     var tempOrder = angular.copy(order); 
     tempOrder.status = 1; 
     angular.forEach(tempOrder.items, function(item){ 
      item.status = 1; 
     }) 
     $http.put('/rest/change/invoice/'+order.id+'/', tempOrder).success(function(){ 
      order = tempOrder; // this doesn't work 
      callback(order) 
     }); 
    }; 

通話功能

this.makeReady({status:1, data:2, items:{status:1}}, function(data){ 
// this data your order variable in service 
})
