vue将毫秒数转化为正常日期格式的实例

export function formatDate (date, fmt) {  if (/(y+)/.test(fmt)) {   fmt = fmt.replace(RegExp.$1, (date.getFullYear() + '').substr(4 - RegExp.$1.length));  }  let o = {   'M+': date.getMonth() + 1,   'd+': date.getDate(),   'h+': date.getHours(),   'm+': date.getMinutes(),   's+': date.getSeconds()  };  for (let k in o) {   if (new RegExp(`(${k})`).test(fmt)) {    let str = o[k] + '';    fmt = fmt.replace(RegExp.$1, (RegExp.$1.length === 1) ? str : padLeftZero(str));   }  }  return fmt; }; function padLeftZero (str) {  return ('00' + str).substr(str.length); };

import {formatDate} from '../../common/filters.js'

filters:{ formatDate(time){  var data = new Date(time);  return formatDate(data,'yyyy-MM-dd'); } },
