獲取當(dāng)前時(shí)間，進(jìn)行轉(zhuǎn)換

getTime:function(){
      var _this = this;
      let yy = new Date().getFullYear();
      let mm = new Date().getMonth()+1;
      let dd = new Date().getDate();
      let hh = new Date().getHours();
      let mf = new Date().getMinutes()<10 ? '0'+new Date().getMinutes() : new Date().getMinutes();
      let ss = new Date().getSeconds()<10 ? '0'+new Date().getSeconds() : new Date().getSeconds();
      _this.gettime = yy+'-'+mm+'-'+dd+' '+hh+':'+mf+':'+ss;
    },

創(chuàng)建定時(shí)器

currentTime(){
      setInterval(this.getTime,500)
    },

在生命周期函數(shù)中觸發(fā)定時(shí)器

created() {
    this.currentTime();    
  },

<p>{{gettime}}</p>
data() {
    return {
      gettime:'',//當(dāng)前時(shí)間
  },
