* Scrollbar - a jQuery plugin for custom scrollbars
|
||||
*
|
||||
* @author Thomas Duerr, me@thomd.net
|
||||
* @date 03.2010
|
||||
* @requires jquery v1.4.2
|
||||
* @version 0.3
|
||||
*
|
||||
*
|
||||
* Usage:
|
||||
*
|
||||
* Append scrollbar to an arbitrary container with overflowed content:
|
||||
*
|
||||
* $('selector').scrollbar();
|
||||
*
|
||||
*
|
||||
* Append scrollbar without arrows on top/bottom:
|
||||
*
|
||||
* $('selector').scrollbar({
|
||||
* arrows: false
|
||||
* });
|
||||
*
|
||||
*
|
||||
*
|
||||
* A vertical scrollbar is based on the following box model:
|
||||
*
|
||||
* +----------------------------------+
|
||||
* | <----------------------------- content container
|
||||
* | +-----------------+ +------+ |
|
||||
* | | | | <-------------- handle arrow up
|
||||
* | | | | | |
|
||||
* | | | +------+ |
|
||||
* | | | | +--+ | |
|
||||
* | | | | | | | |
|
||||
* | | | | | <-------------- handle
|
||||
* | | | | | | | |
|
||||
* | | | | | | | |
|
||||
* | | | | | | | |
|
||||
* | | | | +--+ | |
|
||||
* | | | | | |
|
||||
* | | | | <-------------- handle container
|
||||
* | | | | | |
|
||||
* | | <----------------------------- pane
|
||||
* | | | | | |
|
||||
* | | | | | |
|
||||
* | | | +------+ |
|
||||
* | | | | | |
|
||||
* | | | | <-------------- handle arrow down
|

* | +-----------------+ +------+ |
