用JQuery调用Session的方法

   function GetSession(value) {
          var temp;
          jQuery.ajax({
              type: "POST",
              url: "GetSession.aspx",
              async: false,      //是否ajax同步
              data: "s=" + value,
              success: function(msg) {
                  temp = msg;
              }
          });
          return temp;
      }

        string sessionName = "";
        protected void Page_Load(object sender, EventArgs e)
        {
            sessionName = Request.Form["s"].ToString();
            Response.Write(Session[sessionName]);
            Response.End();
        }
