总是出现 “AJAX服务器返回错误!”

自己初学AJAX,写了一个简单的测试!(js如下)

<!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>
    <title></title>
    <script type="text/javascript">
        function btnOnclick() {
            var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
            if (!xmlhttp) {
                alert("创建xmlhttp异常!");
                return false;
            }
            xmlhttp.open("POST", "1.ashx?ts", false);
            xmlhttp.onreadystatechange = function () {
                if (xmlhttp.readyState == 4) {
                    if (xmlhttp.status == 200) {
                        alert(xmlhttp.responseText);
                        document.getElementById("txtTime").value = xmlhttp.responseText;
                    }
                    else {
                        alert("AJAX服务器返回错误!");
                    }
                }
            }
            xmlhttp.send();
        }
    </script>
</head>
<body>
<input id="txtTime" type="text" />
<input id="btnOK" type="button" value="点击" onclick="btnOnclick()" />
</body>
</html>

 

1.ashx内容如下!

<%@ WebHandler Language="C#" class="GetDate1" %>

using System;
using System.Web;
using System.Web.Services;

    [WebService]
    [WebServiceBinding(ConformsTo=WsiProfiles.BasicProfile1_1)]
    public class GetDate1 : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            context.Response.Write(DateTime.Now.ToString());
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }

    }

 

但是调用的时候总是提示“AJAX服务器返回错误!”,怎么也发现不了错误!希望哪位大侠指点一二!
