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")//根据会员卡号，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\"},");
                sb.Append("{\"id\":\"101\",\"name\":\"销售单列表\",\"pId\":\"1\"},");
                sb.Append("{\"id\":\"102\",\"name\":\"销售单综合查询\",\"pId\":\"1\"},");

                sb.Append("{\"id\":\"2\",\"name\":\"系统管理\",\"pId\":\"0\"},");
                sb.Append("{\"id\":\"103\",\"name\":\"权限组管理\",\"pId\":\"2\"},");
                sb.Append("{\"id\":\"104\",\"name\":\"权限菜单管理\",\"pId\":\"2\"}");
                sb.Append("]");
                Response.Write(sb.ToString());
            }
        }
    }
}
