昨天都好好的 ，但是今天出现了一个脚本错误，变量未定义
大家能不能告诉我怎么解决？

Answer 1

后台定义：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Tmw.HgWeb.BaseClass;
using Tmw.Model;
using System.Collections.Generic;
using AjaxPro;
using Tmw.BLL.EsoftInternalBll;[AjaxPro.AjaxNamespace("ContactRecorder")]
public partial class EsoftInternalUI_OpenCutomer_CustomerList : BasePage
{......}前台调用<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">    <script language="javascript" type="text/javascript" src="../../ucren/ucren-widgets/boot.js"></script>    <script src="../../scripts/jquery/jquery-1_1_2.js" type="text/javascript"></script>    <script type="text/javascript" language="javascript">
    $(document).ready(function(){
        $("#ctl00_ContentPlaceHolder1_ddlProvince").change(function(){
                var sumManner=ContactRecorder.ChangeProvinceQIndex($(this).val()).value;
            
                $("#ctl00_ContentPlaceHolder1_ddlCity").empty();
            
            
                $("#ctl00_ContentPlaceHolder1_ddlCity").append(sumManner);
            });
            
            $("#ctl00_ContentPlaceHolder1_ddlCity").change(function(){
                var values=$(this).val();
                $("#ctl00_ContentPlaceHolder1_hfCity").val(values);
            });
            
            $("#ctl00_ContentPlaceHolder1_txtCTelA").blur(function(){
            
                var message=ContactRecorder.IsTelExists($(this).val()).value;
            alert(message);
                if(message!=""){
                    alert(message);
                    $(this).focus();
                }
            });
    });

脚本错误：‘ContactRecorder’未定义

使用了Jquery好像不能在使用AjaxPro 两者有冲突
