本文实例讲述了jquery简单倒计时实现方法。分享给大家供大家参考，具体如下：

var intDiff = parseInt(60); //倒计时总秒数量

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');

intDiff--;

}, 1000);

}

$(function () {

timer(intDiff);

});

希望本文所述对大家jQuery程序设计有所帮助。
