这是我的代码。非常混乱，但由于我缺乏经验，我无法发现它为什么不起作用。根据我的计算，递减是 js 标准，至少对于毫秒、秒和分钟，不确定小时。
这是代码。预先感谢。
<!DOCTYPE html>

var hours = 1;
var mins = hours * 60;
var secs = mins * 60;

setTimeout('DecrementMilli()',100);

setTimeout('DecrementHours()',100000);
function DecrementMilli() {
currentMilli = secs % 100;
if(currentMilli <= 99) currentMilli = "000" + currentMilli;
secs--;
document.getElementById("tMilli").innerHTML = currentMilli;
if(mill !== -1) setTimeout('Decrement()',100);
}
function DecrementSeconds() {
currentSeconds = secs % 60;
if(currentSeconds <= 9) currentSeconds = "0" + currentSeconds;
secs--;
document.getElementById("tSeconds").innerHTML = currentSeconds;
if(secs !== -1) setTimeout('Decrement()',1000);
}
function DecrementMinutes() {
currentMinutes = Math.round(secs / 60);
if(currentMinutes <= 60) currentMinutes = "00";
mins--;
document.getElementById("tMins").innerHTML = currentMinutes;
if(mins !== -1) setTimeout('Decrement()',10000);
}
function DecrementHours() {
currentHours = Math.round(1440 / 60);
if(currentHours <= 24) currentHours - 1;

您的间隔时间错误。您可以尝试下面的代码。只需将变量放入 html 中即可，例如：
<span id='tHours'>23</span>:<span id='tMins'>59</span>:<span id='tSeconds'>59</span>:<span id='tMilli'>99</span>
JS 喜欢：
var milli = 99;
var sec = 59;
var min = 59;
var hour = 23;
setInterval(function () {
milli = milli == 0 ? 99 : milli - 1;
$('#tMilli').text(double0(milli));
},10);
setInterval(function () {
sec = sec == 0 ? 59 : sec - 1;
$('#tSec').text(double0(sec));
},1000);
setInterval(function () {
min = min == 0 ? 59 : min - 1;
$('#tMin').text(double0(min));
},60000);
setInterval(function () {
hour = hour == 0 ? 23 : hour - 1;
$('#tHour').text(double0(hour));
},1440000);
function double0 (num) {
num = num.toString().length == 1 ? '0' + num : num;
return num;
}
好吧，我解决了我自己的问题，但它不优雅，因为它不是从 24:00:00 开始，而是从 23:59:59 开始。但这只是一个开始。
我会将其发布在这里，以防对任何人有帮助
<script type="text/javascript">
var count = 86400;
var counter = setInterval(timer, 1000);
function timer() {
count = count - 1;
if (count == -1) {
clearInterval(counter);
return;
}
var seconds = count % 60;
var minutes = Math.floor(count / 60);
var hours = Math.floor(minutes / 60);
minutes %= 60;
hours %= 60;
document.getElementById("timer").innerHTML = hours + ":" + minutes + ":" + seconds; // watch for spelling
}
</script>
<span id='timer'></span>
你成功了吗？我的生活中需要这个应用程序哈哈，这篇文章是搜索中为数不多的了解我需要什么的文章之一。
