Code implementation of formatting time in WeChat applet

util.js ---------- //两种方式 1.formatTime 传入参数 Date 返回：年/月/日 const formatTime = date => { const year = date.getFullYear() const month = date.getMonth() + 1 const day = date.getDate() const hour = date.getHours() const minute = date.getMinutes() const second = date.getSeconds() return [year, month, day].map(formatNumber).join('/') + ' ' + [hour, minute, second].map(formatNumber).join(':') }const formatNumber = n => { n = n.toString() return n[1] ? n : '0' + n } module.exports = { formatTime: formatTime, formatTime1: formatTime1 } function formatTime1(n){ n = n.toString() return n[1] ? n : '0' + n } // 2.formatTime1传入参数 （时间戳，格式：如YYYY -MM-DD） //返回：年-月-日（自定义） function formatTime1(number, format) { var formateArr = ['Y', 'M', 'D', 'h', 'm', 's']; var returnArr = []; var date = new Date(number); returnArr.push(date.getFullYear()); returnArr.push(formatNumber1(date.getMonth() + 1)); returnArr.push(formatNumber1(date.getDate())); returnArr.push(formatNumber1(date.getHours())); returnArr.push(formatNumber(date.getMinutes())); returnArr.push(formatNumber1(date.getSeconds())); for (var i in returnArr) { format = format.replace(formateArr[i], returnArr[i]); } return format; }
