终于向Ajax迈出了第一步

前台代码：

    <script src="../Scripts/jquery-1.4.1.js" type="text/javascript"></script>
    <script type="text/javascript">
        function deleteUser(id){
            $.post("UserList.ashx",
            { Id: id },
            function (json) {
                if (json.recode == "1") {
                    alert("删除成功!");
                    //parent.location.reload();此处可以自动刷新页面
                    $("#t"+id).remove();
                } else {
                    alert("删除失败!");
                }
            },
            "json"
            );
        }
    </script>

后台代码：

 

        /// <summary>
        /// 读取用户列表
     　 /// </summary>
       /// <param name="context"></param>
        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/html";

            string id =context.Request.Form["Id"];
            if (UserInfoManager.DeleteUserInfoById(Convert.ToInt32(id)) > 0)
            {
                context.Response.Write("{\"recode\":\"1\"}");
            }
            else
            {
                context.Response.Write("{recode:'2',content:'删除失败'}");
                return;
            }
        }
