数组对象里面对日期进行排序
var hislist = [{ 'id':'1','date','2020-11-21 15:16:09'}, { 'id':'2','date','2020-11-22 10:11:06'}, { 'id':'3','date','2020-11-24 15:32:06'}, { 'id':'4','date','2020-11-25 18:41:46'}];
let Onecycledate: any = hislist; let twocycledate = Onecycledate.hisList; let way: any = Array.from(new Set(twocycledate)); let rows = way.rows; way = rows.sort(function (a, b) { return Date.parse(a.createDate) - Date.parse(b.createDate) }); let createDate = way[0].createDate;
