Answer 5

用一般处理程序去做操作！然后返回数据
参考：
前台： $.ajax({
            url: "Data/GetUserInfo.ashx?method=CheckExistUserName",
            data: { "loginusername": $("#txtUserName").val() },
            type: "post",
            success: function(text) {
                $("#tdUser").empty(); //清空内容
                var item;
                if (text == "False") {
                    item = '<img src="images/ok.png"/>恭喜您,这个帐号可以注册!';
                    IsCheck = true;
                }
                else
                    item = '<img src="images/no.png"/>对不起,这个帐号已经有人注册了!';
                $("#tdUser").append(item);            }
        });
后台：
/// <summary>
        /// 保存用户信息 
        /// </summary>
        /// <param name="context"></param>
        public void SaveMemberInfo(HttpContext context)
        {
            UserOuterManager usermanager = new UserOuterManager();
            try
            {
                //表单读取
                string Yzm = context.Request["Yzm"].Trim();
                if (Yzm != CookieHelper.GetCookieValue("regyzm"))
                {
                    context.Response.Write(usermanager.WriteJsonForReturn(false, "验证码错误！"));
                    return;
                }
                string txtUserName = context.Request["txtUserName"].Trim();
                string txtPwd = context.Request["txtPwd"].Trim();
                string txtEmail = context.Request["txtEmail"].Trim();
                string txtRealname = context.Request["txtRealname"].Trim();
                string txtAddress = context.Request["txtAddress"].Trim();
                string txtPhone = context.Request["txtPhone"].Trim();                //字符串sql注入检测
                if (Tools.IsValidInput(ref txtUserName, true) && Tools.IsValidInput(ref txtPwd, true) && Tools.IsValidInput(ref txtEmail, true))
                {
                    LUserOuter info = new LUserOuter();
                    info.USER_LOGIN_NAME = txtUserName;
                    info.PWD = MD5.MDString(txtPwd);
                    info.EMAIL = txtEmail;
                    info.USER_NAME = txtRealname;
                    info.CONTRACT_ADDRESS = txtAddress;
                    info.TEL_NO = txtPhone;
                    info.REG_TIME = DateTime.Now;
                    info.APP_NAME = "个性化门户";
                    if (usermanager.AddUserOuter(info))
                    {
                        context.Response.Write(usermanager.WriteJsonForReturn(true, "注册用户成功！"));
                    }
                    else
                    {
                        context.Response.Write(usermanager.WriteJsonForReturn(false, "注册用户失败！"));
                    }
                }
            }
            catch (Exception)
            {
                context.Response.Write(usermanager.WriteJsonForReturn(false, "注册用户失败！"));
            }
        }
