Factory возвращающего неопределенный объект

Question

Я использую ионный и angularjs для мобильного приложения, я пытаюсь использовать тянуть, чтобы обновить, но когда обновление (вызов doRefresh из UI) происходит, я получаю сообщение об ошибке

«Uncaught TypeError: не удается прочитать свойство„getFromServer“неопределенных»

вызов getServiceList работает нормально, когда контроллер становится загружен

Я не могу понять, почему serviceListSerice возвращается неопределенный объект. Пожалуйста, помогите

Моего Controller.js

angular.module('starter.controllers', ['ionic', 'ui.bootstrap.datetimepicker']) 

.controller('serviceListCtrl',function($scope,$rootScope,$state,serviceListService){ 


$scope.doRefresh=function(serviceListService,$scope) { 
    serviceListService.getFromServer($scope); //<-this is where i am getting the error 
    //$scope.$broadcast('scroll.refreshComplete'); 
}; 

serviceListService.getServiceList($scope); //<--- this is called successfully 
              //when controller is getting loaded. 
}) 

Моего services.js

angular.module('starter.services', []) 
.factory('serviceListService',function() { 

    return { 


     getServiceList : function($scope) {

Answer 1

Почему вы передаете serviceListService в функции $ области видимости? Он вам не нужен, поскольку он объявлен во всем контроллере. Просто попробуйте это:

$scope.doRefresh = function($scope) { 
    serviceListService.getFromServer($scope); //<-this is where i am getting the error 
    //$scope.$broadcast('scroll.refreshComplete'); 
}; 

Answer 2

Вам не нужно вводить услугу serviceListService снова. Измените код следующим образом и попробуйте!

$scope.doRefresh=function($scope) { 
    serviceListService.getFromServer($scope); //<-this is where i am getting the error 
    //$scope.$broadcast('scroll.refreshComplete'); 
}; 

Answer 3

serviceListService когда passong в область видимости функции перекрывает ссылку на заводе и в настоящее время является локальной переменной функции doRefresh, которые, очевидно, не будет иметь их методы завода, то не передать его как вам не нужно

$scope.doRefresh=function($scope) { 
    serviceListService.getFromServer($scope); //<-this is where i am getting the error 
    //$scope.$broadcast('scroll.refreshComplete'); 
}; 

Answer 4

$scope.doRefresh=function($scope) { 
    serviceListService.getFromServer($scope); 
    //$scope.$broadcast('scroll.refreshComplete'); 
}; 

вам не нужно проходить зависимость для внутренних функций внутри контроллера, завод serviceListService доступен по всему контроллеру
