bootstrap-progressbar - 0.5.0

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 get the value via callback.

Demo

• http://minddust.github.com/bootstrap-progressbar

Usage

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>
      </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>
      </div>

Usage Extended

• Do i need the additional style file?

  • for the horizontal bar with no or filled text: NO

  • for any vertical bars or the horizontal bar with centered text: YES

    <link rel="stylesheet/less" type="text/css" href="bootstrap-progressbar.less">

    or

    <link rel="stylesheet" type="text/css" href="bootstrap-progressbar.css">

• Multiple trigger

  You can trigger progressbar as much as you want. Just change your data attribute and trigger .progressbar() again. All settings made before will be kept. Please have a look at the demo page for a working example.

Customization

1. alignment

   • to use a horizontal progressbar which is align to the right you have to add right to the progress element

     <div class="progress right progress-info">

   • to use a vertical progressbar you have to add vertical to the progress element

     <div class="progress vertical progress-info">

   • to use a vertical progressbar which is align to the bottom you have to add vertical and bottom to the progress element

     <div class="progress vertical bottom progress-info">

2. 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,
           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
   • update callback where you can grab the actual percentage value
   • done callback which indicates when progressbar is filled to the given value
   • fail callback where you can grab an error message when something went wrong

3. animation

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

   1. horizontal

      • 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;
        }

   2. vertical

      • less

        .progress.vertical .bar {
            .transition(height 2s ease-in-out);
        }

      • css

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

Known Problems

• Looks like iOS Safari is flooring the width of the transition. So if you want to display text with a correct value you have to use a full bar width greater or equal 100px.
