EasyUI Ajax请求收集

1、普通ajax请求：

        para = {};        para.action = "getUserInfo";//post请求的参数用Request.Params["action"];接收        para.timespan = new Date().getTime();        para.id = val;        $.ajax({            url: "ashx/bg_user.ashx",            data: para,            type: "POST",            dataType: "json",            success: function (data) {                //data为json对象集合，所以此处用[0]                return data[0].UserName;                           }        });
