//安装时间格式化插件
npm install moment
<script>
import moment from 'moment'
const getTime = () => {
const now = new Date(); // 当前日期
const nowYear = now.getFullYear(); //当前年
const nowMonth = now.getMonth(); //当前月 (值为0~11)
const d = now.getDate(); //当天
const firstDay = new Date(nowYear, nowMonth, 1, 0, 0); // 本月开始时间
const LastDay = new Date(nowYear, nowMonth + 1, 0, 23, 59); // 本月结束时间
const toDay = new Date(nowYear, nowMonth, d); // 本月今天
//如果想获取本月第一天00:00和最后一天23:59
//const firstDay = new Date(nowYear,nowMonth,1,00,00)
//const LastDay = new Date(nowYear, nowMonth+1,0, 23,59);
//const toDay = new Date(nowYear, nowMonth, d, 23,59,59); // 获取今天23时:59分:59秒
};
//此时获取的是标准时间,时间格式化为YY-MM-DD HH:mm:ss
console.log(moment(firstDay).format('YY-MM-DD HH:mm:ss'));//加入是12月,2022-12-1 00:00:00
