• api/workAPI.js

定义一个dateTimeWeek

function format2Digit(n) {//判断时间是否需要加0if (n < 10) {return "0" + n;} else {return n;}}export function dateTimeWeek() {//设置返回显示的日期时间格式var date    = new Date();var year    = format2Digit(date.getFullYear());var month   = format2Digit(date.getMonth() + 1);var day     = format2Digit(date.getDate());var hour    = format2Digit(date.getHours());var minute  = format2Digit(date.getMinutes());var second  = format2Digit(date.getSeconds());var weekday = date.getDay();var weeks   = new Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六");var week = weeks[weekday];//这里设置你要显示的格式return `${year}年${month}月${day}日 ${hour}:${minute}:${second} ${week}`;}

• vue中导入并使用

<script>
import { dateTimeWeek } from '@/api/platformApi';......export default {name: 'work',data() {return {timeTextTimer: undefined,nowTimeText: new Date()}},created() {this.timeTextTimer = setInterval(() => {this.nowTimeText = dateTimeWeek();});},
