剩余时间
剩余时间（倒计时）是怎么做的？期望是能显示天时分，最好能用jquery实现？
------解决方案--------------------
javascript计时器
------解决方案--------------------
设定时间.getTime()-当前时间.getTime()转换成毫秒数后将毫秒转换成天时分秒试试
------解决方案--------------------

<span id="daysLeft"></span>

<script type="text/javascript">

/*

**参数:target(目标日期),类型:string,格式:year/month/day

*/

(function tC(target){



    var day=24*60*60*1000,

        hour=60*60*1000,

        minute=60*1000,

        second=1000;



    var tE=(new Date(target)).getTime(),

        now=new Date(),

        tN=now.getTime(),

        hN=now.getHours(),

        mN=now.getMinutes(),

        sN=now.getSeconds();



    var time=tE-tN,

        _day=parseInt(time/day),

        _hour=parseInt(time%day/hour),

        _minute=parseInt(time%day%hour/minute),

        _seconds=parseInt(time%day%hour%minute/second),

        str='距离 '+target+' 还有: '+_day+'天'+_hour+'时'+_minute+'分'+_seconds+'秒';



    document.getElementById('daysLeft').innerHTML=str;

    setTimeout(function(){tC(target)},1000);

    

})('2013/12/25');
