我正在尝试根据番茄工作法制作一个倒数计时器，你工作 25 分钟然后休息一下。我正在使用 jQuery.countdown 和 moment.js 插件在 Javascript 和 jQuery 中编写页面。我有它，所以当用户点击开始按钮时，它会倒计时 25 分钟，但是在计时器完成后，我希望有两个中断选项再次重新启动计时器。然后它只是循环 25 分钟->休息->25 分钟->休息->等，具体取决于用户在倒计时结束时按下的按钮。

倒计时完成后的按钮现在是如何无能为力的。我觉得我需要重置计时器，但是 jQuery.countdown 的文档有点难以通过。

 <div class="container-fluid">
 <p>start timer and then get to work</p>
 <div class="container-fluid">
    <div class="container-fluid">
      <span id="timer"></span>
    </div>
  </br>
    <div class="containter-fluid" id="timer-buttons">
      <span><button type="button" class="btn btn-secondary btn-sm" id="btn-start-timer">start timer</button></span>
    </div>
</div>



<script type="text/javascript">

  var $timer = $('#timer');
  var $timerButtons = $('#timer-buttons');

  $('#btn-start-timer').click(function(event) {
    // get the current time when button clicked
    var currentTime = moment();
    // add 25 minutes for interval
    var timerInterval = moment(currentTime).add(25.0, 'm');
    // format interval
    var timerIntervalFormatted = moment(timerInterval).format('YYYY/MM/DD HH:mm:ss');

    // start the 25 minute timer and at the end popup two buttons for breaks
    $timer.countdown(timerIntervalFormatted, function(event) {
      $(this).html(event.strftime('%M:%S'));
    }).on('finish.countdown', function() {
      $timerButtons.html('<span><button type="button" class="btn btn-secondary btn-sm" id="btn-short-break">short break</button></span> <span><button type="button" class="btn btn-secondary btn-sm" id="btn-long-break">long break</button></span>');
    });
  });

  $('#btn-short-break').click(function(event) {
    var currentTime = moment();
    var shortBreak = moment(currentTime).add(1.0, 'm');
    var shortBreakFormatted = moment(shortBreak).format('YYYY/MM/DD HH:mm:ss');

    $timer.countdown(shortBreakFormatted, function(event) {
      $(this).html(event.strftime('%-M:%S'));
    }).on('finish.countdown', function() {
      $timerButtons.html('<span><button type ="button" class="btn btn-secondary btn-sm" id="btn-start-timer">start timer</button></span>');

    });
  });

  $('#btn-long-break').click(function(event) {
    var currentTime = moment();
    var longBreak = moment(currentTime).add(2.0, 'm');
    var longBreakFormatted = moment(longBreak).format('YYYY/MM/DD HH:mm:ss');

    $timer.countdown(longBreakFormatted, function(event) {
      $(this).html(event.strftime('%-M:%S'));
    }).on('finish.countdown', function() {
      $timerButtons.html('<span><button type ="button" class="btn btn-secondary btn-sm" id="btn-start-timer">start timer</button></span>');

    });
  });

使用 id="checkout-countdown" 作为 html 标签

对于 jQuery：

<script src="~/Assets/global/plugins/countdown/jquery.countdown.js"></script>

<script>
    $(function () {            
            startCountDown();           
    });

    function startCountDown() {
        var currentDateTime=new Date($.now());
        var austDay = new Date(currentDateTime);
        austDay.setSeconds(austDay.getSeconds() + @expirationSecondsRemaining);

        $('#checkout-countdown').removeClass('is-countdown').html('');

        $('#checkout-countdown').countdown({
            until: austDay, compact: true,
            description: '', onExpiry: liftOff, 'format': 'MS', alwaysExpire: true
        });
    }

    function liftOff() {
        var result = new Object();
        result.message = "Your session has expired. We've released your selected price. Please try selecting price again.";
        result.type = "info";
        app.showConfirmation(result);

        //recursively call start count down
        startCountDown();
    }
</script>
