bootstrap-progressbar - 0.9.0
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.
What's new in v0.9.0?
- Fix #49 runtime option override support
- Fix #48 extend bower.json
Note: this version replaces the not official supported
aria-valuetransitionsgoal
withdata-transitionsgoal
which may affect (or brick) your progressbars.
Note: Bootstrap's low percentage styles (introduced in 3.2.0) causes flickering under some circumstances (e.g. slow transitions). To preserve correct progressbar functionality + appearance this bs feature is reverted in v0.8.3. (and reverted by bootstrap in 3.3.0)
Note: Stacked progressbars are not supported by now.

Multiple trigger
You can trigger progressbar as much as you want. Just change your attribute(s) and trigger
.progressbar()
again. All settings made before will be kept.
Settings
default values
Progressbardefaults = transition_delay: 300 refresh_speed: 50 display_text: 'none' use_percentage: true { return percent + '%'; } { return amount_part + ' / ' + amount_total; } update: $noop done: $noop fail: $noop;
transition_delay
Is the time in milliseconds until the animation starts.
This could be useful to delay the start on the initial page load like:
;
refresh_speed
Is the time in milliseconds which will elapse between every text refresh, aria-valuenow
attribute update and update
callback call.
display_text
Determines if and where to display text on the progressbar. Possible options:
none
no textfill
text on filled barcenter
text on center (this mode changes css / html due to styling requirements)
use_percentage
If text will be displayed - this option determines whether to show the percentage value or the amount.
So if use_percentage
is false and aria-valuemin
and aria-valuemax
are not set (or to 0
and 100
) the value will be the same but amount_format
will be used to format the result.
Example:
<div class="progress-bar" data-transitiongoal="75">
with use_percentage: true
is the final text: 75%
with use_percentage: false
is the final text: 75 / 100
percent_format
Is a function which returns the text format for progressbar with use_percentage: true
.
It takes 1 argument which is the current percent value.
amount_format
Is a function which returns the text format for progressbar with use_percentage: false
.
It takes 3 argument which are the current-, the max- and the min-amount.
update
Is a callback function which will be called while the progressbar is transitioning ;)
Depends on refresh_speed
.
It takes 2 argument which is the current percent value and a reference to the attached progressbar element.
done
Is a callback function which will be called when the transition process is done.
It takes 1 argument which is a reference to the attached progressbar element.
fail
Is a callback function which will be called when an error occurs.
It takes 1 argument which is the error message.
Customisation
alignment
-
to use a horizontal progressbar which is align to the right you have to add
right
to theprogress
element. -
to use a vertical progressbar you have to add
vertical
to theprogress
element. -
to use a vertical progressbar which is align to the bottom you have to add
vertical
andbottom
to theprogress
element.
animation
to change the animation itself you have to overwrite either less or css
-

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.
