     3 function AjaxXmlHttp(url)
     4    {
     5        var xmlhttp;
     6                try
     7                {   
     8                    xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
     9                }

    10                catch(e)
    11                {
    12                   try
    13                   {
    14                        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    15                   }

    16                   catch(e)
    17                   {
    18                        try
    19                        {
    20                        }

    21                        catch(e)
    22                        {
    23                            xmlhttp = new XMLHttpRequest();
    24                        }

    25                   }

    26                }

    27                
    28                 xmlhttp.onreadystatechange = function()
    29                 {         
    30                   if(xmlhttp.readystate==4)
    31                    {                  
    32                        
    33                         if(xmlhttp.status == 200)
    34                         {
    35                            
    36                           alert(xmlhttp.ResponseText);                       
    37                         }

    38                         else
    39                         {
    40                            alert("读取数据出错,错误端口号是:"+xmlhttp.status);
    41                         }

    42                    }

    43               }
               
    44              xmlhttp.open("get",url,true);
    45              xmlhttp.send(null);              
    46    }
    二、处理xmlhttp
    HTML
    1<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Active.aspx.cs" Inherits="Ajax_Active" %>
    多余的html代码应除掉。

    CS
     1using System;
     2using System.Data;
     3using System.Configuration;
     4using System.Collections;
     5using System.Web;
     6using System.Web.Security;
     7using System.Web.UI;
     8using System.Web.UI.WebControls;
     9using System.Web.UI.WebControls.WebParts;
    10using System.Web.UI.HtmlControls;
    11
    12public partial class Ajax_Active : System.Web.UI.Page
    13{
    14    protected void Page_Load(object sender, EventArgs e)
    15    {
    16
    17        string id = Request["id"].ToString();
    18        string flag = Request["flag"].ToString();
    19        if (flag == "no")
    20        {
    21            string sql = "update userinfo set isactivate='0' where userid='" + id + "'";
    22            DAL.SQLHelper.ExecuteNonQuery(DAL.SQLHelper.CONN_STRING, CommandType.Text, sql, null);
    23            Response.Write("取消激活成功");
    24        }

    25        else if (flag == "yes")
    26        {
    27            string sql = "update userinfo set isactivate='1' where userid='" + id + "'";
    28            DAL.SQLHelper.ExecuteNonQuery(DAL.SQLHelper.CONN_STRING, CommandType.Text, sql, null);
    29            Response.Write("激活成功");
    30        }

    31        
    32    }

    33}
    三、调用
