  1.   

    asp的程序代码，出什么问题了？
      

  2.   

    IIS下运行  给你个代码
    Default.aspx<script type="text/javascript" language="javascript">
            function validateloginname()
            {
            var loginname=document.getElementById("Text1").value;         xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
            xmlHttp.onreadystatechange=getdata;
            xmlHttp.Open("GET","validate.aspx?loginname="+loginname,true);
            xmlHttp.Send();
            }
            function getdata()
            {
            if(xmlHttp.readystate==4)
            {
            if(xmlHttp.status==200)
            {
            var text=xmlHttp.responseText;
            if(text=="1")
            {
                document.getElementById("td1").innerHTML="用户名已存在";
                document.getElementById("Text1").style.borderColor="Black";
                document.getElementById("Text1").focus();
                 document.getElementById("Text1").value="";
            }
            else
            {
                 document.getElementById("td1").innerHTML="OK";
                 document.getElementById("Text1").style.borderColor="Red";
            }
            }
            }
            }
        </script>
    <input id="Text1" type="text" runat="server" onblur="validateloginname()" />
    validate.aspx protected void Page_Load(object sender, EventArgs e)
        {
            string loginname = Request.QueryString["loginname"];        if (loginname == "mcluzhi")
            {
                Response.Write("1");
            }
            else
            {
                Response.Write("0");
            }
        }
