        var date = $('#datepicker').val();
        var startTime = $('#starttimepicker').val();

        alert(`您预定了 ${date} ${startTime}-${endTime} 的会议室`);
        selectedTimeslot.removeClass('available').addClass('unavailable').removeClass('selected');
        $('#reserveBtn').prop('disabled', true);
      });
    });

    function updateAvailableTimeslots(date) {
      $('#availableTimeslots').html('');
      var startTime = $('#starttimepicker').val();
      var endTime = $('#endtimepicker').val();
      if (startTime && endTime) {
        var startHour = parseInt(startTime.split(':')[0]);
        var endHour = parseInt(endTime.split(':')[0]);
        for (var hour = startHour; hour < endHour; hour++) {
          var timeslot = $('<div></div>').addClass('timeslot available');
          timeslot.text(hour + ':00 - ' + (hour + 1) + ':00');
          $('#availableTimeslots').append(timeslot);
        }
      } else {
        $('#addToCartBtn').prop('disabled', true);
      }
    }
  </script>
</body>

</html>
```

在这个实现中，用户可以选择预定日期和开始结束时间，并在可预定时间范围内拖拽选择时间段。预定按钮将被激活并点击后会展示一个简单的提示信息，并将已选择的时间段设置为不可预定。
