刚写的例子：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>倒计时</title>
</head>
<script>
window.onload = function(){
var iTotalTime = 23 + 8;//每天8点距离第二天8的时间
var oHour = document.getElementById("hour");
var oMin = document.getElementById("min");
var oSen = document.getElementById("sen");
var iDin = 59;
//一秒执行一次
setInterval(function(){
var dDate = new Date();//获得本地时间
var getMin = 59 - dDate.getMinutes();
var getSen = 59 - dDate.getSeconds();
oHour.innerHTML = iTotalTime - dDate.getHours();
oMin.innerHTML = getMin > 9 ?getMin:"0"+getMin;
oSen.innerHTML = getSen > 9 ?getSen:"0"+getSen;
},1000);
}
</script>
<body>
<div>
本场剩余：<span id="hour">00</span>时<span id="min">00</span>分<span id="sen">00</span>秒
</div>
</body>
</html>
