Question

我是Angular和MVC的新手，我已经创建了一个显示代码   记录到表格视图中。

用户可以通过单击“编辑”和“删除”来编辑和删除该记录   链路

但是当我点击编辑链接 TypeError时，它会显示错误：   v2.UpdataData不是函数

它还显示错误 TypeError：$ http.get不是函数   当我点击删除链接

任何人都可以帮我解决这个问题。提前谢谢。

Controller.js

    //update data of table
        $scope.UpdataData = [];
        //UpdateData();
        $scope.UpdateData = function (StateMaster) {

            debugger;
            getData.then(function (StateMaster) {

                StateID: $scope.StateID;

            }, function () {
                alert('Error in getting records');
            });
    }
 $scope.DeleteData = [];
    $scope.DeleteData = function (r, index) {
        var retval = DataService.DeleteData(r.StateID).success(function (msg) {
            $scope.countrydata.splice(index, 1);

您的代码中存在此问题

line $scope.UpdateData = function (StateMaster

因为你正试图运行你的$ scop功能但功能是工厂所以你必须尝试

factory.UpdateDate

似乎在角度定义factory时存在问题，您可以尝试以下方式

    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");
   }

你可以放置你的功能，只是尝试它返回你的价值

TypeError：v2.UpdataData不是函数
