三、异步请求的后台数据：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace CssStudyWeb.AjaxPage
{
public partial class GetAjax : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["z"] == "sdfww234edfsd")//依据会员卡号，查询会员卡信息
{
StringBuilder sb = new StringBuilder();
sb.Append("[");
sb.Append("{"id":"1","name":"销售单管理","pId":"0"},");
