使用ajax做检测用户名..老是返回服务器页的文本............................谁来帮看看

Question

string urlstring = HttpContext.Current.Request.Url.ToString();
if (urlstring.Contains("regemail"))
{
  string email =HttpContext.Current.Request["regemail"];
  WriteStream(user.CheckEmail(email));
  Response.end();
}

Answer 1

刚刚服务器端的写错,不好意思if (urlstring.Contains("regcheckname"))
        {
            string nickname =HttpContext.Current.Request.Query("regcheckname");
            string result = user.CheckNickName(nickname);
            WriteStream(result);
        }
WriteStream方法
    public void WriteStream(string str)
    {
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.Write(str);
        HttpContext.Current.Response.End();
        //HttpContext.Current.Response.Close();
    }

Answer 2

你的WriteStream方法大体应该是根据check的结果输出的吧，我想很可能是你输出的最后没加上Response.End()导致的

Answer 3

WriteStream方法
    public void WriteStream(string str)
    {
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.ContentType="text/plain";//加上这行
        HttpContext.Current.Response.Write(str);
        HttpContext.Current.Response.Flush();//加上这行.
        HttpContext.Current.Response.End();
        //HttpContext.Current.Response.Close();
    }

Answer 4

function CheckName(_nickname)
{
    if(IsNull(_nickname)){alert("请输入你的昵称");return false;}
    var ajax=new Ajax();
    var str='regcheckname='+_nickname;
    ajax.open("POST","ajaxserver/AjaxProServer.aspx",true);
    ajax.setRequestHeader("Content-Length",str.length); 
    ajax.setRequestHeader("content-type","application/x-www-form-urlencoded");
 ajax.send(str);
    ajax.onreadystatechange=function()
    {
        if(ajax.readyState==4 && ajax.status==200)
        {
            var msg=ajax.responseText;
            alert(msg);
            if(msg=='不存在')
                $('txtnickname_c').innerHTML="此昵称不存在,可以注册";
            else
                $('txtnickname_c').innerHTML="此昵称已经存在.......";     
        }
    }
   
}

Answer 5

if(Request["regcheckname"]!=null)
{
Response.Writer("you zhi");
Response.End();
}

Answer 7

原来是客户端,ajax对象没有向服务器端 get...
