Error: [ng:areq] Argument 'approvalCtrl' is not a function, got undefined

Question

        width: 260px;
        height: 50px;

这是approvalCtrl.js

    app.controller('approvalCtrl', function ($scope, GetDataService) {
        function getAllDataRequest() {
            GetDataService.getRequestData().then(function (emp) {
                $scope.requestList = emp.data;
            }, function (error) {
                alert('failed to fetch data');

            });
        }

    })(angular.module('myapplication'));
});

这是approvalController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MyApplication.Service.Controllers
{
    public class ApprovalController : Controller

        // GET: Approval
        public ActionResult Index()

            return View();

        public JsonResult GetAll()
        {
            List<TRN_SERVICE_REQUEST> reqdata = new List<TRN_SERVICE_REQUEST>();
            using (RREntities ed = new RREntities())
            {
                reqdata = ed.TRN_SERVICE_REQUEST.ToList();
                return new JsonResult { Data = reqdata, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
            }
        }
    }
}

这是app.js

(function () {
    'use strict';

    var app = angular.module('myapplication', ['common.core', 'common.ui'])
        .config(config)
        .run(run);

    config.$inject = ['$routeProvider'];
    function config($routeProvider) {

                closeEffect: 'none'
            });

            $('.fancybox-media').fancybox({
                openEffect: 'none',
                closeEffect: 'none',
                helpers: {
                    media: {}

                $('.row-offcanvas').toggleClass('active');
            });
        });
    }

})();

页面结果如图所示 Result Page

为什么得到错误的结果不是一个函数？

提前致谢

Answer 1

您需要在 HTML

中定义应用

<div ng-app = "myapplication"></div>

Answer 2

我觉得你把自调用函数写错了。论点没有正确放置。应该在下面一行。

(function (app) {
    'use strict';

    app.controller('approvalCtrl', function ($scope, GetDataService) {
        function getAllDataRequest() {
            GetDataService.getRequestData().then(function (emp) {
                $scope.requestList = emp.data;
            }, function (error) {
                alert('failed to fetch data');

            });
        }

    });
})(angular.module('myapplication'));
