HTML5 & jQuery Progress bar plugin : Percentage Loader

A jQuery plugin that utilises HTML canvas to show an animated percentage loader widget suitable for loading screens or displaying feedback during long-running tasks.


Html5 & jQuery PercentageLoader is a jQuery plugin for displaying a progress widget in more visually striking way than the ubiquitous horizontal progress bar / textual counter. The plugin takes miniminal installation and is simple and flexibile to use. It makes use of HTML 5 canvas for a rich graphical appearance with only a 10kb (minified) javascript file necessary (suggested web font optional). It uses vectors rather than images so can be easily deployed at various sizes by simply adjusting the initial parameters.
