Create Countdown Timers Using Bootstrap 4 Progressbar - progressBarTimer

progressBarTimer is a jQuery plugin that lets you create smooth, customizable countdown timers or loading progress bars using Bootstrap 4's progress bar component.

The plugin dynamically changes the styles of the countdown timer depending on the remaining time. Also provides a callback function which will be fired when the countdown is completely finished.

How to use it:

1. The plugin requires the latest jQuery library and Bootstrap 4 framework.

<!-- Stylesheet -->
<link rel="stylesheet" href="" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
<!-- JavaScript -->
<script src="" integrity="sha384-tsQFqpEReu7ZLhBV2VZlAu7zcOV+rXbYlF2cqB8txI/8aZajjp4Bqd+V6D5IgvKT" crossorigin="anonymous"></script>
<script src="" integrity="sha384-ZMP7rVo3mIykV+2+9J3UJ46jBk0WLaUAdn689aCwoqbBJiSnjAK/l8WvCWPIPm49" crossorigin="anonymous"></script>
<script src="" integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy" crossorigin="anonymous"></script>

2. Generate a default countdown timer (60 seconds) in a container element you specify.

<div id="example"></div>
var myCountdown = $('#example').progressBarTimer({ 
    autostart: true // default false

3. If you want to start the countdown timer manually.

var myCountdown = $('#example').progressBarTimer();

4. Set the tartget time in seconds you want to countdown from.

var myCountdown = $('#example').progressBarTimer({ 
    autostart: true,
    timeLimit: 120 // default: 60

5. Customize the appearance of the countdown timers.

var myCountdown = $('#example').progressBarTimer({ 

    // warning threshold in seconds
    warningThreshold: 5,

    // base style
    baseStyle: '',

    // warning style
    warningStyle: 'bg-danger',

    // complete style
    completeStyle: 'bg-success',

    // should the timer be smooth or stepping
    smooth: false, 
    // striped progress bar
    striped: false,

    // animated stripes
    animated: false,

    // height of progress bar
    // 0 = default height
    height: 0

6. If you want to display percentage value or remaining time inside the countdown timer.

var myCountdown = $('#example').progressBarTimer({ 

    label : {
      show: true,
      type: 'percent' // or 'seconds' => 23/60


7. Execute a function when the countdown timer is finished.

var myCountdown = $('#example').progressBarTimer({ 

    onFinish: function() {}


8. API methods.

// start the countdown timer

// stop the countdown timer

// extend the current timer

// add seconds to the countdown timer



  • Fixed warningThreshold not working;
  • Allows to refresh the progressbar;
