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";
