调用示例：


var countTime = function () {
  var eles = $('.count_time'),
    len = eles.length;
  for (; len > 0; len--) {
    var ele = eles.eq(len - 1);
    (function (ele) {
      startTime = new Date(ele.attr('data-start-time')).getTime(),
          endTime = new Date(ele.attr('data-end-time')).getTime(),
          alarm = new Alarm(startTime, endTime, function (second, minute, hour, day) { //计时钟
            ele.text(hour + ':' + minute + ':' + second);
          }, function () { //倒计时结束
            ele.text('00:00:00');
            window.location.reload();
          });
      alarm.start();
    })(ele);
  }
};
countTime();
