date.js
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); }
组件内使用:
<template> <div> <span>{{date | formatDate}}</span> </div> </template> import {formatDate} from './js/date.js'; export default { date() { return { date: 1496311370052 } }, filters: { formatDate(time) { var date = new Date(time); return formatDate(date, 'yyyy-MM-dd hh : mm'); } }, }
