时间处理

 时间加8小时

date.setHours(date.getHours() + 8);  

yyyyMMddhhmmss =>yyyy-MM-dd hh:mm:ss

  v.SysTransTime = t.replace(/^(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})$/, "$1-$2-$3 $4:$5:$6");

 

 

  ENdateTranslation(date){
            var dt = new Date(date);
            var m=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Spt","Oct","Nov","Dec");
            var w=new Array("Mon","Tue","Wed","Thu","Fri","Sat","Sun");
            var d=new Array("st","nd","rd","th");
            let mn=dt.getMonth();
            let wn=dt.getDay();
            let dn=dt.getDate();
            var dns;
            if(((dn%10)<1) ||((dn%10)>3)){
                dns=d[3];
            } else{
                dns=d[(dn%10)-1];
                if((dn==11)||(dn==12)){
                    dns=d[3];
                }
            }
            return (w[wn-1] +" , " +" "+dn + m[mn]);
     },
 
var scheduledDateTime="2019-12-31 09:10:00"
ENdateTranslation(scheduledDateTime)

 // 对Date的扩展，将 Date 转化为指定格式的String

// 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符， 
// 年(y)可以用 1-4 个占位符，毫秒(S)只能用 1 个占位符(是 1-3 位的数字) 
// 例子： 
// (new Date()).Format("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423 
// (new Date()).Format("yyyy-M-d h:m:s.S")      ==> 2006-7-2 8:9:4.18 
Date.prototype.Format = function (fmt) {
    var o = {
        "M+": this.getMonth() + 1, //月份 
        "d+": this.getDate(), //日 
        "H+": this.getHours(), //小时 
        "m+": this.getMinutes(), //分 
        "s+": this.getSeconds(), //秒 
        "q+": Math.floor((this.getMonth() + 3) / 3), //季度 
        "S": this.getMilliseconds() //毫秒 
    };
    if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    for (var k in o)
    if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
    return fmt;
}

调用： 
var time1 = new Date().Format("yyyy-MM-dd");
var time2 = new Date().Format("yyyy-MM-dd HH:mm:ss");

　　

function renderTime(date) {
  var dates = new Date(date).toJSON();
  return new Date(+new Date(dates) + 8 * 3600 * 1000).toISOString().replace(/T/g, ' ').replace(/\.[\d]{3}Z/, '') 
}

　　ios里面

new Date（）里面的时间必须是"$1/$2/$3 $4:$5:$6"格式的 才能转换出来
