formatNumber = n => {
n = n.toString()
return n[1] ? n : '0' + n
}
// 时间格式化
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(':')
}
使用：
formatTime(new Date())
