js获取三天后的日期

• setDate

  getNowAddTreeFormatDate() {
    var date = new Date();
    date.setDate(date.getDate()+3);//获取3天后的日期
    var seperator1 = "-";
    var seperator2 = ":";
    var month = date.getMonth() + 1;
    var monthStr:string;
    var day = date.getDate();
    var dayStr:string;
    if (month >= 1 && month <= 9) {
        monthStr = "0" + month.toString();
    }else{
      monthStr =  month.toString();
    }
    if (day >= 0 && day <= 9) {
        dayStr = "0" + day.toString();
    }else{
        dayStr = day.toString();
    }
    var currentdate = date.toISOString(); //date.getFullYear() + seperator1 + month + seperator1 + dayStr + 'T00:00:00+08:00'
            ;
    return currentdate;
  }

• 加上3天的时间戳

       // 交付时间为当前时间3天后
       let year=new Date(new Date().getTime()+259200000).getFullYear();
       let month=new Date(new Date().getTime()+259200000).getMonth()+1;
       let newMonth:any;
       if(month<10){
       newMonth='0'+month;
       }else{
         newMonth=month;
       }
       let day=new Date(new Date().getTime()+259200000).getDate();
       this.task.handInTime=year+'-'+newMonth+'-'+day;

• 手机振动

      var p = document.getElementById("message");
      var supportsVibrate = "vibrate" in navigator;
      supportsVibrate ? y() : n();
      var u = navigator.userAgent;
      var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1; //android终端
      var isIOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端
      function y() {
          p.innerHTML = "你的手机已被我控制了，我就问你怕不怕，慌不慌 !!!";
          navigator.vibrate([1000, 1000, 1000, 1000, 1000]);
      }
  
      function n() {
          isIOS ? p.innerHTML = "土豪用的苹果手机，惹不起惹不起" : "不支持震动";
      }
