Angularjs TypeError:v2.UpdateData不是函数

我是Angular和MVC的新手，我已经为display创建了一个代码 记录到表视图中

用户可以通过单击“编辑和删除”按钮编辑和删除该记录 链接

但当我点击编辑链接TypeError时，它显示了错误： v2.UpdateData不是一个函数

它还显示了errorTypeError:$http.get不是一个函数 当我点击删除链接

有人能帮我解决这个问题吗。提前谢谢

您的代码中存在此问题

line$scope.UpdateData=函数（StateMaster

当你试图运行你的$scop功能，但功能是工厂的，所以你必须像这样尝试

factory.UpdateDate

---

在角度定义

工厂时似乎有问题，您可以尝试下面的方法

    var app = angular.module('myApp', []);

    app.factory('testFactory', function(){
        return {
            sayHello: function(text){
                return "Factory says \"Hello " + text + "\"";
            },
            sayGoodbye: function(text){
                return "Factory says \"Goodbye " + text + "\"";
            }  
        }               
    });

   function HelloCtrl($scope, testService, testFactory)
   {
      $scope.fromFactory = testFactory.sayHello("World");
   }

你可以放置你的函数，然后试试它是否返回你的值
什么是数据服务的代码？？？参见controller.js@PranayRana，我刚刚附上了我的服务代码这是compiletime错误或runtime？？runtime@PranayRanacan你可以试试我建议的方法…首先尝试简单，然后选择大代码…即首先尝试调用factory方法，如果它能工作的话，那么在调用服务器端函数时，将http代码放入其中是没有问题的，因为我已经在同一个文档中创建了3-4个工厂，而且一切都很好@PranayRana@DheerajSharma-我发现问题，请参阅我的更新答案…您必须调用工厂功能，即工厂。udpatedata为$scope未更新函数数据您遇到错误我按照您所说的进行了更改，但不幸的是，它显示了错误“ReferenceError:factory未定义”现在我的表视图中没有显示任何数据@PranayRana@DheerajSharma-你一次尝试的事情太多了…我建议你一步一步来，首先按照我的建议定义工厂，然后尝试在你的控制器中使用工厂，然后进行大的改变
