时间戳转各种不同的日期格式

方法:

const timestampToTime = function (timestamp, format) { 
    let date = new Date(timestamp) // 时间戳为10位需*1000，时间戳为13位的话不需乘1000
    let Y = date.getFullYear()
    let M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1)
    let D = date.getDate() < 10 ? '0' + date.getDate() : date.getDate()
    let h = date.getHours() < 10 ? '0' + date.getHours() : date.getHours()
    let m = date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes()
    let s = date.getSeconds() < 10 ? '0' + date.getSeconds() : date.getSeconds()
    let dateStr =   `${Y}${M}${D}${h}${m}${s}`
    let pattern = /^(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})$/
    return dateStr.replace(pattern, format)
}

使用方式:

timestampToTime(1534317479000, '$1年$2月$3日$4时$5分$6秒')
