If set the current queue is cleared. - * - ADD: Added onTick callback event which gets called when the percentage is updated. - * - ADD: Added stable (as in "non-crashing") versions of the additions which first surfaced in the (unreleased) 0.3.2 release - * Preloading support partially implemented in IE as all versions (IE6,7&8) are quite hard to tame (one time they work, the next reload they don't anymore) - * v 0.3.2 - 2008.04.09 (*UNRELEASED*) - * - ADD: implemented preloading of images to avoid slight flicker when switching images (BUGGY!) - * - ADD: percentage image now has class percentImage and percentage Text now has class percentText; This allows you to style the output easily. - * v 0.3.1 - 2008.02.20 - UPD: fixed queue bug when animate was set to false (thanks Jamie Chong) - * - UPD: update Prototype to version 1.6.0.2 - * v 0.3.0 - 2008.02.01 - ADD: animation queue, prevents from the progressbar getting stuck when multiple calls are made during an animation - * - UPD: multiple barImages now work properly in Safari - * v 0.2.1 - 2007.12.20 - ADD: option : set boxImage - * ADD: option : set barImage (one or more) - * ADD: option : showText - * v 0.2 - 2007.12.13 - SYS: rewrite in 2 classs including optimisations - * ADD: Config options - * v 0.1 - 2007.08.02 - initial release - * - * @see http://www.barenakedapp.com/the-design/displaying-percentages on how to create a progressBar Background Image! - * - * Licensed under the Creative Commons Attribution 2.5 License - http://creativecommons.org/licenses/by/2.5/ - * - *****************************************************************/ - - - /** - * CONFIG - * ------------------------------------------------------------- - */ - - // Should jsProgressBarHandler hook itself to all span.progressBar elements? - default : true - var autoHook = true; - - // Default Options - var defaultOptions = { - animate : true, // Animate the progress? - default: true - showText : true, // show text with percentage in next to the progressbar? - default : true - width : 120, // Width of the progressbar - don't forget to adjust your image too!!! - boxImage : 'images/bramus/percentImage.png', // boxImage : image around the progress bar - barImage : 'images/bramus/percentImage_back.png', // Image to use in the progressbar.
