vue 实时获取当前年月日时间星期

1.在data中定义一个变量，存储时间

data(){return {nowTime:''}},

2.给定一个div

<div>{{nowTime}}</div>

3.js部分 调用nowTimes

//显示当前时间（年月日时分秒）timeFormate(timeStamp) {let year = new Date(timeStamp).getFullYear();let month =new Date(timeStamp).getMonth() + 1 < 10? "0" + (new Date(timeStamp).getMonth() + 1): new Date(timeStamp).getMonth() + 1;let date =new Date(timeStamp).getDate() < 10? "0" + new Date(timeStamp).getDate(): new Date(timeStamp).getDate();let hh =new Date(timeStamp).getHours() < 10? "0" + new Date(timeStamp).getHours(): new Date(timeStamp).getHours();let mm =new Date(timeStamp).getMinutes() < 10? "0" + new Date(timeStamp).getMinutes(): new Date(timeStamp).getMinutes();let ss =new Date(timeStamp).getSeconds() < 10? "0" + new Date(timeStamp).getSeconds(): new Date(timeStamp).getSeconds();let week = new Date(timeStamp).getDay();let weeks = ["日","一","二","三","四","五","六"];let getWeek = "星期" + weeks[week];this.nowTime = year + "年" + month + "月" + date +"日"+" "+hh+":"+mm+':'+ss+getWeek ;},nowTimes(){this.timeFormate(new Date());setInterval(this.nowTimes,1000);this.clear()},clear(){clearInterval(this.nowTimes)this.nowTimes = null;}

4.复制粘贴即可用，主要是使用定时器，每秒调用，最后清除定时器，清除函数
