Uncaught TypeError: undefined is not a function when ASP.NET client accesses the Service

Question

我正在尝试创建一个 AJAX 启用的 WCF 服务和一个访问该服务的 ASP.NET 客户端。

我得到的错误是：

Uncaught TypeError: undefined is not a function

在这一行：

var service = new WcfService.Service1();

这是我的 asp.net 代码：

<%@ Page Language="C#" AutoEventWireup="True" CodeBehind="GridView.aspx.cs" Inherits="ASPUserManager.Presentation.AspNetUI.GridView" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

            <asp:ServiceReference Path="~/Service1.svc" />
        </services>
    </asp:ScriptManagerProxy>

 </form>

    <script>
        $(document).ready(function () {
            var service = new WcfService.Service1();
            service.GetAllUsers(onSuccess, null, null);

            function onSuccess(result) {
                alert(result);
            }
        });
    </script>

</body>
</html>

Service1.svc.cs

namespace WcfService
{
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Service1 : IService1
    {
        private ExceptionManager exManager;

        IApplicationService applicationService;

        public Service1()
        {
            this.applicationService = new ApplicationService();
        }

        #region Members

        public UsersDTO GetUser(UsersDTO userDTO)
        {
            return this.Process(() =>
            {
                return this.applicationService.GetUser(userDTO);
            });
        }

}

IService1.cs

namespace WcfService
{
    [ServiceContract(Namespace = "WcfService")]
    public interface IService1
    {
        [OperationContract]
        UsersDTO GetUser(UsersDTO userDTO);
    }
}

我希望我提供了所有必要的信息来分析这个问题。如果没有，请告诉我。如果有人可以帮助我，那就太好了。我只是看不出可能是什么问题:)

您需要在调用 $(document).read

之前包含 jQuery 脚本

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
    <script>
        $(document).ready(function () {
            debugger;
            var service = new WcfService.Service1();
            //service.GetAllUsers(onSuccess, null, null);

            function onSuccess(result) {
                alert(result);
            }
        });
    </script>

正如 Cristina Alboni 所建议的，我尝试调试 javascript 代码，发现我试图以错误的方式初始化 wcf，而且我不得不更改 [=12] 中的一些配置=].

Uncaught TypeError: undefined is not a function when ASP.NET client accesses the Service

Uncaught TypeError: undefined is not a function when ASP.NET client accesses the Service

javascript

c#

asp.net

wcf

jquery
