jquery倒计时代码
<pre>
<span id="day_show">0天</span>
<strong id="hour_show">0时</strong>
<strong id="minute_show">0分</strong>
<strong id="second_show">0秒</strong>
</pre>

<pre>

timer(50);

function timer(intDiff) {
window.setInterval(function() {
var day = 0,
hour = 0,
minute = 0,
second = 0; //时间默认值
if (intDiff > 0) {
day = Math.floor(intDiff / (60 * 60 * 24));
hour = Math.floor(intDiff / (60 * 60)) - (day * 24);
minute = Math.floor(intDiff / 60) - (day * 24 * 60) - (hour * 60);
second = Math.floor(intDiff) - (day * 24 * 60 * 60) - (hour * 60 * 60) - (minute * 60);
}
if (minute <= 9) minute = '0' + minute;
if (second <= 9) second = '0' + second;
$('#day_show').html(day + "天");
$('#hour_show').html('<s id="h"></s>' + hour + '时');
$('#minute_show').html('<s></s>' + minute + '分');
$('#second_show').html('<s></s>' + second + '秒');
//用于毫秒倒计时
//countdaojishi1('haomiao_show', 99,10);
intDiff--;
}, 1000);
}

注意haomiao_show是id元素

function countdaojishi1(obj, startv, endv) {
var options = {  
 useEasing: false,
  useGrouping: false,
  separator: ',',
  decimal: '.',
};
var demo = new CountUp(obj, startv, endv, 0, 2.5, options);
if (!demo.error) {  
demo.start();
} else {  
console.error(demo.error);
}
}
