    <script type="text/javascript" src="jquery-1.8.3.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            var times = 60 * 100; // 60秒
            countTime = setInterval(function() {
                times = --times < 0 ? 0 : times;
                var ms = Math.floor(times / 100).toString();

                if(ms.length <= 1) {
                    ms = "0" + ms;
                }
                var hm = Math.floor(times % 100).toString();
                if(hm.length <= 1) {
                    hm = "0" + hm;
                }
                if(times == 0) {
                    alert("游戏结束");
                    clearInterval(countTime);
                }
                // 获取分钟、毫秒数
                $(".a").html(ms);
                $(".b").html(hm);
            }, 10);
        });
    </script>
    <style>
        .warp{
