js判断时间戳是否在本周、根据时间戳获取近七天以及近30天

 判断时间戳是否在本周

isWeek:function (time) {

    // 当前时间

    var timestamp = Date.parse(new Date());

    var serverDate = new Date(timestamp);

    //本周周日的的时间

    var sundayTiem = timestamp + ((7 - serverDate.getDay())* 24 * 60 * 60 * 1000)

    var SundayData = new Date(sundayTiem);

    //年

    var tomorrowY = SundayData.getFullYear();

    //月

    var tomorrowM = (SundayData.getMonth() + 1 < 10 ? '0' + (SundayData.getMonth() + 1) : SundayData.getMonth() + 1);

    //日

    var tomorrowD = SundayData.getDate() < 10 ? '0' + SundayData.getDate() : SundayData.getDate();

    console.log(tomorrowY+'-'+tomorrowM+'-'+tomorrowD);

    // 本周周一的时间

    var mondayTime = timestamp - ((serverDate.getDay()-1) * 24 * 60 * 60 * 1000)

根据时间戳获取 近7天以及近30天

// 获取当天往后的七天或者一个月

function timeForMat(count) {

  let time1 = new Date()

  time1.setTime(time1.getTime())

  let Y1 = time1.getFullYear()

  let M1 = ((time1.getMonth() + 1) > 10 ? (time1.getMonth() + 1) : '0' + (time1.getMonth() + 1))

  let D1 = (time1.getDate() > 10 ? time1.getDate() : '0' + time1.getDate())

  let timer1 = Y1 + M1 + + D1 // 当前时间

  let time2 = new Date()

  time2.setTime(time2.getTime() + (24 * 60 * 60 * 1000 * count))

  let Y2 = time2.getFullYear()

  let M2 = ((time2.getMonth() + 1) > 9 ? (time2.getMonth() + 1) : '0' + (time2.getMonth() + 1))

  let D2 = (time2.getDate() > 9 ? time2.getDate() : '0' + time2.getDate())

  let timer2 = Y2 + M2 + D2 // 之后的七天或者一个月

  return {

    t1: timer1,

    t2: timer2

  }
