将json数据按角度js推送到现有数组

Question

我在将数据推送到现有阵列时遇到问题。您可以看到我将数据发布到表中，但是，当用户输入8位数的条形码时，我喜欢将数据推送到表中。

您要将新项目添加到范围之外的其他元素（工厂内），必须执行以下操作：

        $scope.autoAddItem = function () {
            if (($scope.BarcodeValue + '').length == 8) {
                $scope.items.push({
                    "barcodeVal": $scope.BarcodeValue,
                    "courierType": "PICKUP",
                    "userName": "aspuser"
                });

                $scope.BarcodeValue = "";
            }
        };

如果你想让工厂里面的所有东西都是这样的（并忽略上面的改变）：

angular.module('app.pickUpServ', []).factory('pickUpServ', ['$rootScope', '$http',
function($rootScope, $http) {
    return {
        getPickUpList: function(callback) {
            var _this = this; 
            $http({
                method: 'POST',
                url: 'app/Service/CourierService.asmx/BarcodeList',
                data: {
                    "bardcodeVal": "",
                    "courierType": "PICKUP",
                    "userName": "aspuser"
                },
                contentType: 'application/json; charset=utf-8',
                dataType: 'json',
            })
            .success(function(data) {
            _this.items = data.d;
            callback(_this.items) //This gonna set to $scope the items in factory and angular  
                              //link the object items to $scope.items (Code not tested but must work)
            })
            .error(function(error) {
                console.log('Error - getPickUpList');
            });
        },
        items: [{
                    "bardcodeVal": "",
                    "courierType": "PICKUP",
                    "userName": "aspuser"
                }],
        add: function(item) {
            this.items.push(item);
            console.log(item);
        }
    };
}
]);

想出来......我用$rootScope.items = data.d;解决了我的问题。谢谢大家的帮助！

angular.module('app.pickUpServ', []).factory('pickUpServ', ['$rootScope', '$http',
