<script type="text/javascript">
    //获取当前时间戳
    var nowTime = $.now();
    var timebox = $('#time');
    var countTime = new Date(nowTime + 1000*60*6);
    timebox.countdown(countTime,function (event) {
        //控制时间格式
        var format = event.strftime('秒杀倒计时:%D天 %H时 %M分 %S秒');
        timebox.html(format)
    }).on('finish.countdown',function () {
        alert("计时完成后执行的函数")
