本文实例讲述了js倒计时简单实现方法的代码，分享给大家供大家参考，具体如下：
= 86400 * 30) {
month = Math.floor(second / (86400 * 30)) + '月';
second = second % (86400 * 30);
}
if (second >= 86400) {
day = Math.floor(second / 86400) + '天';
second = second % (86400);
}
if (second >= 3600) {
hour = Math.floor(second / 3600) + '小时';
second = second % 3600;
}
if (second >= 60) {
minute = Math.floor(second / 60) + '分';
second = second % 60;
}
if (second > 0) {
second = second ? second + '秒' : '';
}
return month + day + hour + minute + second;
}
jquery插件形式:
= 86400 * 30) {
month = Math.floor(second / (86400 * 30)) + '月';
second = second % (86400 * 30);
}
if (second >= 86400) {
day = Math.floor(second / 86400) + '天';
second = second % (86400);
}
if (second >= 3600) {
hour = Math.floor(second / 3600) + '小时';
second = second % 3600;
}
if (second >= 60) {
minute = Math.floor(second / 60) + '分';
second = second % 60;
}
if (second > 0) {
second = second ? second + '秒' : '';
} else {
return tip;
}
return month + day + hour + minute + second;
};
$this.html(self._timeDown(second));
setInterval(function () {
second--;
$this.html(self._timeDown(second));
},1000)
};
// 使用方式
$('.remain_time').timeDown({second:1000,tip:'已过期'})
希望本文所述对大家JavaScript程序设计有所帮助。
