ajax.dll和AjaxPro.dll 使用ajax传值到后台方法时的问题

这是页面源码

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="AjaxProDemo.aspx.cs" Inherits="Web.AjaxProDemo" %>



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

<head runat="server">

    <title></title>

    <script type="text/javascript">

        function getData() {

            var time = AjaxProDemo.GetTime();

            document.getElementByIdx_x_x("sp").innerText = time.value;

        }

        function start() {

            intervalid = setInterval("getData()", 1000);

        }

    </script>

</head>

<body onload="start()">

    <form id="form1" runat="server">

    <div>

        <span id="sp"></span>

    </div>

    </form>

</body>

</html>

这是后台源码

protected void Page_Load(object sender, EventArgs e)

        {

            AjaxPro.Utility.RegisterTypeForAjax(typeof(AjaxProDemo));//AjaxProDemo为web页名称

        }



        [AjaxPro.AjaxMethod]

        public string GetTime()

        {

            return DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");

        }

不管是用ajax.dll 还是AjaxPro.dll，运行时都会报

这个错误，请问是怎么回事啊？
