javascript - get方法:用户名异步请求asp服务端报错？

Question

js代码如下:

<script type="text/javascript">
var res = '<%=trim(request("Nickname_count"))%>';//常量 0用户名不存在 ；1用户名存在
</script>
<script  type="text/javascript" >
function Ajax(obj){
    $.ajax({
       type:"get",
        url:"ajax.asp",
        data:"Nickname="+$('#inputUser').val(),
        beforeSend:function(){
            $('#yhm').append(process_request);
        },
        //用户名检测

        success:function(res){
            if(res=="0"){
                $('#inputUser').attr('class','FramepWarn');
                showInfo("yhm",username_exist);
                change_submit("true");//禁用提交按钮
            }
           if(res=="1"){
               $('#inputUser').attr('class','FramepPass');
               showInfo("yhm",msg_can_rg);
               change_submit("true");//禁用提交按钮

           }
        }
    });
    console.log(res);

}
</script>

asp.net代码如下：

<%
Call OpenData()
Set rs=server.CreateObject("adodb.recordset")
Nickname=SafeRequest(request.Form("Nickname"),0)
Usercontact=SafeRequest(request.Form("Usercontact"),0)
username_count=0:Nickname_count=0
username_count=cdbl(getValueBySql("select count(*) from Sbe_Users where Usercontact='"&Usercontact&"'"))
'if username_count>0 then goBack("该手机号已经在本站注册，请换一个注册！")
Nickname_count=cdbl(getValueBySql("select count(*) from Sbe_Users where Nickname='"&Nickname&"'"))
'if Nickname_count>0 then goBack("该会员名已被使用，请换一个注册！")
response.Write(Nickname_count,username_count)
set rs=nothing
Call CloseDataBase()
%>

页面报错:

ajax异步错误，大家来看看问题是出在哪了？
