直接引入common.js這個封裝好的時間工具或者單獨用stringToDate（str）這個方法。

function stringToDate(str){
		    var tempStrs = str.split(" ");
		    var dateStrs = tempStrs[0].split("-");
		    var year = parseInt(dateStrs[0], 10);
		    var month = parseInt(dateStrs[1], 10) - 1;
		    var day = parseInt(dateStrs[2], 10);

		    var date = new Date(year, month, day);
		    return date;
		}

首先因爲後臺返回來的時間是yyyy-mm-dd hh🇲🇲ss的字符串，所以先把字符串轉成時間戳，然後才能調用getFullYear()，.getMonth()+1，.getDate()，.getDay()，.getHours()，.getMinutes()，.getSeconds()等。

然後再用方法轉成對應的英文，比方說月份轉成對應的英文：

$(function(){
	var m=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Spt","Oct","Nov","Dec");
	mn=stringToDate(json.date).getMonth();//json.date是從後臺獲取過來的字符串時間
	//alert(m[mn]);
			})

例子：

function stringToDate(str){
		    var tempStrs = str.split(" ");
		    var dateStrs = tempStrs[0].split("-");
		    var year = parseInt(dateStrs[0], 10);
		    var month = parseInt(dateStrs[1], 10) - 1;
		    var day = parseInt(dateStrs[2], 10);

		    var date = new Date(year, month, day);
		    return date;
		}

$(function(){
   
	$.each(json.info,function(i,e){
		var m=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Spt","Oct","Nov","Dec");
		var day=e.pubdate.split("-")[2];
		mn=stringToDate(e.pubdate).getMonth();
		$($(".news-lists article")[i]).find(".news-day").html(day.split(" ")[0]);//日
		$($(".news-lists article")[i]).find(".news-month").html(m[mn]);//月
	})
})
