javascript - 如何在这个倒计时脚本中添加天数，使其变成DD-HH-MM-SS？

我在 jQuery 中有这个脚本:

// Auction countdown script
$(function () {

var remaining = $("#countdown").text(),
    regex = /\d{2}/g,
    matches = remaining.match(regex),
    hours = matches[0],
    minutes = matches[1],
    seconds = matches[2],
    remainingDate = new Date();

remainingDate.setHours(hours);
remainingDate.setMinutes(minutes);
remainingDate.setSeconds(seconds);

var intvl = setInterval(function () {
    var totalMs = remainingDate.getTime(),
        hours, minutes, seconds;

remainingDate.setTime(totalMs - 1000);

hours = remainingDate.getHours();
minutes = remainingDate.getMinutes();
seconds = remainingDate.getSeconds();

if (hours === 0 && minutes === 0 && seconds === 0) {
    alert('done');
}

$("#countdown").text(
    (hours >= 10 ? hours : "0" + hours) + ":" +
    (minutes >= 10 ? minutes : "0" + minutes)  + ":" +
    (seconds >= 10 ? seconds : "0" + seconds));

}, 1000);

});

现在，这需要一个字符串并为其进行 HHMMSS 倒计时。我希望它是 DDHHMMSS，但我似乎无法让它工作。谁能指出我正确的方向？

谢谢!
