bootstrap-progressbar - 0.4.1

bootstrap-progressbar is a jQuery plugin which extends the basic twitter-bootstrap progressbar. It provides the ability to animate the progressbar by adding Javascript in combination with the preexisting css transitions. Additionally you can display the current progress information in the bar or via callback.



  1. include bootstrap-progressbar.js:

    <script type="text/javascript" src="bootstrap-progressbar.js"></script>
  2. activate bootstrap-progressbar functionality on progressbars of your choice:

    $(document).ready(function() {
        $('.progress .bar').progressbar();
  3. set the data attribute and remove the width style attribute (alternatively you can set it to 0)

    1. data-percentage:

      <div class="progress progress-info">
          <div class="bar" data-percentage="75"></div>
    2. data-amount-part and data-amount-total:

      <div class="progress progress-info">
          <div class="bar" data-amount-part="1337" data-amount-total="9000"></div>


  1. text and delay

    simply add additional parameters when activating the script:

    $(document).ready(function() {
        $('.progress .bar').progressbar({
            transition_delay: 300
        ,   refresh_speed: 50
        ,   display_text: 2
        ,   use_percentage: true
        ,   border_radius: '4px'
        ,   update: doSomethingCool( current_percentage ) { .. }
        ,   done: doSomethingCool( ) { .. }
        ,   fail: doSomethingCool( error_message ) { .. }
    • transition_delay is the time in milliseconds until the animation starts

    • refresh_speed is the time in milliseconds which will elapse between every text refresh / callback call

    • display_text determines whether the text will be displayed

      • 0 no text (this mode doesn't change any css / html)
      • 1 text on filled bar (this mode doesn't change any css / html)
      • 2 text on center (this mode changes css / html due to styling requirements)
    • use_percentage determines whether the text will be displayed in percent or amount

    • border_radius hook to change the border radius of the progressbar

      • you only have to set this if you are using centered text AND have overwritten the default bootstrap value
    • update hook where you can grab the actual percentage value

    • done hook which indicates when progressbar is filled to the given value

    • fail hook where you can grab an error message when something went wrong

  2. to change the animation itself you have to overwrite either less or css

    • less:

      .progress .bar {
        .transition(width 2s ease-in-out);
    • css:

      .progress .bar {
          -webkit-transition: width 2s ease-in-out;
          -moz-transition: width 2s ease-in-out;
          -ms-transition: width 2s ease-in-out;
          -o-transition: width 2s ease-in-out;
          transition: width 2s ease-in-out;
