角度对象如何获取另一个对象的值

Question

如何使对象继承其他对象的所有属性。

这是代码：

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 
    }); 
} 

在成功的情况下：改变该对象的值。

Answer 1

尝试在你的$scope.allOrders直接编辑的顺序，看看是否能得到您的行为你正在寻找。

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; 
     }); 
    }

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) 
     }); 
    }; 

通话功能

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