首先解释一下我想要获取的数据，利用Ajax和后端进行异步请求

然后后端发送过来的数据通过alert()是这样的

{
   "msg":"成功","code":20000,"records":[                    {
   "fw_ctime":"2020-08-01 08:00:00","fw_title":"光明日报聚焦:北斗三号系统全面建成给北斗产业带来什么","fw_description":"澎湃财经", "fw_picurl":"https://imagecloud.thepaper.cn/thepaper/image/80/830/440.jpg","fw_url":"https://www.thepaper.cn/newsDetail_forward_8535860"},                    {
   "fw_ctime":"2020-08-01 08:00:00","fw_title":"深圳监管沙盒首批应用亮相：华为等申请的智能数字信用卡入围","fw_description":"澎湃财经","fw_picurl":"https://imagecloud.thepaper.cn/thepaper/image/80/729/885.jpg","fw_url":"https://www.thepaper.cn/newsDetail_forward_8527727"},                    {
   "fw_ctime":"2020-08-01 08:00:00","fw_title":"美国众议院批准2021年1.3万亿美元支出计划","fw_description":"澎湃财经","fw_picurl":"https://imagecloud.thepaper.cn/thepaper/image/80/824/844.jpg","fw_url":"https://www.thepaper.cn/newsDetail_forward_8535430"}]}

//解析代码如下: $.ajax("../ViewUpdateController/showView",{
                   type:"get",                dataType:"text",                success:function(result){
   					var obj=JSON.parse(result);                    alert(obj.records);                    $.each(obj.records,function(i,json){
                       	alert(json.fw_title);                    	//将会获取到每次循环的值                     })                }            })
