在vue項目中顯示實時時間（年月日時分秒）

1.在data中定義一個變量，存儲時間

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

2.給定一個div

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

3.js部分

 //顯示當前時間（年月日時分秒）
    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();
      this.nowTime = year + "年" + month + "月" + date +"日"+" "+hh+":"+mm+':'+ss ;
    },
    nowTimes(){
      this.timeFormate(new Date());
      setInterval(this.nowTimes,1000);
      this.clear()
    },
    clear(){
      clearInterval(this.nowTimes)
      this.nowTimes = null;
    }

4.復制粘貼即可用，主要是使用定時器，每秒調用，最后清除定時器，清除函數
