asp.net 异步更新jquery.$.ajax方法

 function strings() {
            alert(6666);
            try {
                $.ajax({
                    type: "GET",
                    url: "Json.aspx",
                    dataType: "xml",
                    contentType: "application/xml;charset=utf-8",
                    success: function (xml) {
                        $("TextBox2").value = $(xml).find("resultString").children("text1").text();
                        var id = $(xml).find("resultString").children("text1").text();
                        alert(id);


                    },
                    error: function () { alert("出错了") }
                });
            }
            catch (e) {
                throw e;
            }
            alert(44444);
        }

转入到json.aspx页后访问xml，然后读取xml,结果总是提示出错了（json也代码运行后）；
json页代码如下：
protected void Page_Load(object sender, EventArgs e)
{
Response.Write(11111);

Response.ContentType = "text/xml";
Response.Charset = "utf-8";
Response.Write( resultString());
Response.End();

}
public string aa;
public string resultString()
{
StringBuilder result = new StringBuilder();
result.Append("<?xml version='1.0' encoding='utf-8'?>");
result.Append("<Alltext>");
result.Append("<text1> ");
result.Append("first right");
result.Append("</text1>");

result.Append("</Alltext>");

XmlDocument doc = new XmlDocument();
doc.LoadXml(result.ToString());
return result.ToString();
}

}
[解决办法]
url: "Json.aspx",

不用加路径？ 确认地址对吗
[解决办法]
还有json.aspx页面前台除了<%Page ...%>外，不能有其他内容
否则解析不了xml
[解决办法]

引用:

JavaScript code?1234567891011121314151617181920212223 function strings() { alert(6666); try { $.ajax({ type: "GET", ……

Response.Write(11111); 这个去掉

前台赋值也不对$("#TextBox2").val($(xml).find("Alltext").children("text1").text());
[解决办法]

$.ajax({
                    type: "GET",
                    url: "Json.aspx",
                    dataType: "html",
                    success: function (data) {
                        $("TextBox2").value = $(xml).find("resultString").children("text1").text();
                        var id = $(xml).find("resultString").children("text1").text();
                        alert(id);
 
 
                    },
                    error: function () { alert("出错了") }
                });
