// /** * morebits.js * =========== * A library full of lots of goodness for user scripts on Wikipedia. * (It should work on other MediaWiki wikis as well, despite some Wikipedia-specific object naming.) * * The highlights include: *  - QuickForm class - generates quick HTML forms on the fly *  - MediaWiki.api class - makes calls to the Wikipedia API (or the API of any MediaWiki wiki) *  - MediaWiki.page class - modifies pages on the wiki (edit, revert, delete, etc.) *  - MediaWiki class - contains some utilities for dealing with wikitext *  - Status class - a rough-and-ready status message displayer, used by the Wikipedia classes *  - SimpleWindow class - a wrapper for jQuery UI Dialog with a custom look and extra features * * Dependencies: *  - The whole thing relies on jQuery. But most wikis should provide this by default. *  - QuickForm, SimpleWindow, Status, and the portlet stuff rely on the "morebits.css" file for their styling. *  - SimpleWindow relies on jquery UI Dialog (ResourceLoader module name 'jquery.ui.dialog'). *  - QuickForm tooltips rely on Tipsy (ResourceLoader module name 'jquery.tipsy'). *    For external installations, Tipsy is available at. *  - To create a gadget based on morebits.js, use this syntax in MediaWiki:Gadgets-definition: *      * GadgetName[ResourceLoader|dependencies=jquery.ui.dialog,jquery.tipsy]|morebits.js|morebits.css|GadgetName.js * * Most of the stuff here doesn't work on IE < 9. It is your script's responsibility to enforce this. * * This library is maintained by the maintainers of Twinkle. * For queries, suggestions, help, etc., head to Wikipedia talk:Twinkle on English Wikipedia. * The latest development source is available at. */

(default) * * setPageSection(pageSection) *   pageSection - integer specifying the section number to load or save.
