  • js 获取 最近七天 30天 昨天的方法 -- 转

    自己用到了 找了下  先附上原作的链接  http://www.cnblogs.com/songdongdong/p/7251254.html

    原谅我窃取你的果实  谢谢你谢谢你 ~

    先附上我自己用到的 

    //最近七天和最近三十天时间
    function timeForMat (count) {
    // 拼接时间
      let time1 = new Date()
      time1.setTime(time1.getTime() - (24 * 60 * 60 * 1000))
      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 // 之前的7天或者30天
      // return {
      // // t1: timer1,
      // // t2: timer2
      // }
      return Y2 + '-' + M2 + '-' + D2 + ' 00:00:00';
    }
    // 获取最近7天
    function sevenDays () {
      let timer = timeForMat(7)
      return timer;
    }
    // 获取最近30天
    function thirtyDays () {
      let timer = timeForMat(30)
      return timer
    }
    调用
     sevenDays ();
     thirtyDays ();
    搞定啦啦啦~~~~

    下面的是原作哦~~~~

    function formatDate (val) {

    iDays = parseInt(Math.abs(oDate1 - oDate2) / 1000 / 60 / 60 / 24)
    return iDays + 1
    }

    export {
    formatDate,
    countDate,89 yesterday,
    sevenDays,
    thirtyDays
