MVC视图中处理Json

/// <summary>
        /// 登录
        /// </summary>
        /// <param name="value"></param>
        /// <returns></returns>
        public JsonResult Login()
        {
            List<FACTORY> userList = new List<FACTORY>
            {
              new FACTORY{FACTORY_NAME="zzl",FACTORY_CODE="bfyxzls@sina.com"},
              new FACTORY{FACTORY_NAME="zhz",FACTORY_CODE="zhanghangzheng@sina.com"}, }; 
              JsonResult json = new JsonResult 
             { 
                Data = userList 
             }; 
              return Json(json); }

//return Json(json, JsonRequestBehavior.AllowGet);//前台AJAX如果是GET用这句

//什么时候用GET请求呢，当我们直接在浏览器中输入网址时，其实就是一个GET请求

//如果我们直接输入/Home/TestList这个网址，它会提示我们下载这个JSON格式的文档

        $("#Get").click(function () {

                url: "Test/Login",              
                dataType: ‘json‘,
