我的 Angular 控制器是否针对我包含工厂的方式进行了明确定义？

Question

我在我的 todoController 中使用一个工厂。我不确定 $scope 参数和工厂参数是否以正确的方式编写，因为我的控制器方法不再起作用。

这是正确的方法吗？

这是我的控制器：

facebookExample.controller('todoController', ['$scope', function($scope,   PaypalService) {
// Initialize the todo list array
//if local storage is null save the todolist to local storage
$scope.todoList = [];
$scope.DoRequested = [];
scope.FundingProcess = [];

if (localStorage.getItem("mytodos") === null)
{
localStorage.setItem("mytodos", angular.toJson($scope.todoList));
}else
{
//set the todolist from local storage
$scope.todoList = angular.fromJson(localStorage.getItem("mytodos"));
}

// Add an item function
$scope.todoAdd = function(){

//check to see if text has been entered, if not exit
if ($scope.todoInput === null || $scope.todoInput === ''){ return; }

//if there is text add it to the array
$scope.todoList.push({todoText:$scope.todoInput, 
  todoAdmin:'' , doRequested: '', beingFunded: '', 
   adminAprovedRequest:false, currentFund: 0, userAproved: false, user_email:'' , userdidWork: "false", adminCheckedWork: "false",
     done:false});

//clear the textbox
$scope.todoInput = "";

//resave the list to localstorage
localStorage.setItem("mytodos", angular.toJson($scope.todoList));
};
//Do button
$scope.do = function(x){
$scope.DoRequested.push(x);
// Send email notifier to admin 
/*
$.ajax({
type: “POST”,
url: 'https://mandrillapp.com/api/1.0/messages/send.json',
data: {
‘key’: ‘n3ZIdxXIRIZbvUWw6Z34wA’,
‘message’: {
  ‘from_email’: ‘noreply@you-serve.org’,
  ‘to’: [
      {
        ‘email’: ‘RECIPIENT_NO_1@EMAIL.HERE’,
        ‘name’: ‘RECIPIENT NAME (OPTIONAL)’,
        ‘type’: ‘to’
      },
      {
        ‘email’: ‘RECIPIENT_NO_2@EMAIL.HERE’,
        ‘name’: ‘ANOTHER RECIPIENT NAME (OPTIONAL)’,
        ‘type’: ‘to’
      }
    ],
  ‘autotext’: ‘true’,
  ‘subject’: ‘NEW TASK ASSIGNMENT REQUEST!’,
  ‘html’: ‘<div!’
}
}
}).done(function(response) {
console.log(response); // if you're into that sorta thing
});
*/
};
$scope.fund = function(x){
//$scope.FundingProcess.push(x);
PaypalService.initPaymentUI().then(

   function(){
       PaypalService.makePayment($scope.donationAmount, "Task Funding").then(
           function(data){
               if(data.response.state === "approved"){
                   alert("Successful transaction !");
               }

               else{
                   alert("Error !");
               }
           }

           );
   }     
   );  
};

$scope.remove = function() {
//copy list
var oldList = $scope.todoList;
//clear list
$scope.todoList = [];
//cycle through list
angular.forEach(oldList, function(x) {
  //add any non-done items to todo list
    if (!x.done) $scope.todoList.push(x);
});
//update local storage
 localStorage.setItem("mytodos", angular.toJson($scope.todoList));
};
//The Update function
//This waits 100ms to store the data in local storage
$scope.update = function() {
//update local storage 100 ms after the checkbox is clicked to allow it to process
setTimeout(function(){
localStorage.setItem("mytodos", angular.toJson($scope.todoList));
},100);
};
}]);

这是我的工厂：

facebookExample.factory('PaypalService', ['$q', '$ionicPlatform', 'shopSettings', '$filter', '$timeout', function ($q, $ionicPlatform, shopSettings, $filter, $timeout) {



    var init_defer;
    /**

        });

        return init_defer.promise;

    }

没有通读，但控制器需要这样定义....

facebookExample.controller('todoController', ['$scope','PaypalService', 
    function($scope, PaypalService) {
    //code to be executed.
}]);

这样，如果您缩小代码，Angular 就知道它需要控制器定义中的字符串 $scope 和 PaypalService。您可以在以下链接中阅读有关定义控制器和注入服务的更多信息。
