Jquery倒计时一天

Question

我有一个按小时、分钟和秒工作的倒计时 jquery。到目前为止，这非常有效。但是我希望它也算一天

这是JS FIDDLE

HTML

<div id="counttime">24:00:00</div>
<div id="cons"></div>

JQUERY

    function pad(num) {
  return num<10?"0"+num:num;
}
$(function() {
  var tCont = $('#counttime');
  var timer = tCont.html().split(':');

  if (timer.length === 2) timer.unshift(0);
  var endMilli= timer[0]*60*60*1000;
  endMilli += timer[1]*60*1000
  endMilli += timer[2]*1000;
  if(endMilli > 0) {
    var endTime = new Date(Date.now()+endMilli);   
$("#cons").append("<br>"+endTime);
    var tId = setInterval(function() {
      var diff = endTime.getTime()-Date.now();
      if (diff<=0) {
        tCont.html("00:00:00");
        clearInterval(tId);
      }
      else {
        var d = new Date(diff);
        hh = pad(d.getUTCHours()); 
        mm = pad(d.getMinutes());
        ss = pad(d.getSeconds());
        tCont.html(""+hh+":"+mm+":"+ss);
      }
    },300);      
  }
});

Answer 1

您的hh 部分应乘以天数！

hh = pad(d.getUTCHours() + d.getDay()*24); 

您也应该添加月份...不确定这是否容易。 或者你可以试试这个：

var hours = Math.abs(date1 - date2) / 36e5;
hh = pad(hours); 

36e5 = 60*60*1000 毫秒

Answer 2

您必须调整代码以允许 4 个部分，然后添加一行来评估天数：

dd = pad( (diff - diff % (864e5))/864e5 ),
