//1. 简单页面展示用 
       export default {    data() {      return {        time: 1516703495241      };    },    filters: {      formatDate: function (value) {        let date = new Date(value);        let y = date.getFullYear();        let MM = date.getMonth() + 1;        MM = MM < 10 ? ('0' + MM) : MM;        let d = date.getDate();        d = d < 10 ? ('0' + d) : d;        let h = date.getHours();        h = h < 10 ? ('0' + h) : h;        let m = date.getMinutes();        m = m < 10 ? ('0' + m) : m;        let s = date.getSeconds();        s = s < 10 ? ('0' + s) : s;        return y + '-' + MM + '-' + d + ' ' + h + ':' + m + ':' + s;      }    }  }

 2. 复杂业务使用 moment.js

安装： cnpm install moment --save

vue中使用：

import moment from 'moment'    
     
      {
   {dateBegin | formatDate}}
     
    filters: {      formatDate: function (value) {        return moment(value).format('YYYY-MM-DD')      }    },        submit() {            console.log(moment(this.dateBegin).format('YYYY-MM-DD'))        }
