==Before ResourceLoader==
{{MW 1.16|and earlier}}
MediaWiki 1.16 shipped with jQuery version 1.3.2 with some patches by [[User:Trevor Parscal|Trevor Parscal]] and [[User:Catrope|Roan Kattouw]] to fix jQuery bug [http://dev.jquery.com/ticket/5081 #5081] (see [[Special:Code/MediaWiki/60697|r60697]] and [[Special:Code/MediaWiki/61700|r61700]]).

In 1.16, the jQuery file is in <tt>skins/common/jquery.js</tt> and the minified version is <tt>jquery-min.js</tt> in the same directory.

Extensions can use OutputPage's includeJQuery method, which has existed since [[Special:Code/MediaWiki/61431|r61431]], to avoid loading minified version of jQuery core multiple times. It should be noted that includeJQuery does not support jQuery plugins and such.

To include it, paste the following at the bottom of {{ll|LocalSettings.php}}:

<syntaxhighlight lang="php" style="overflow:auto;">
// Include jQuery
function wfIncludeJQuery() {
global $wgOut;
$wgOut->includeJQuery();
}
$wgExtensionFunctions[] = 'wfIncludeJQuery';
</syntaxhighlight>

=== MediaWiki 1.16: jQuery.noConflict===

Please pay attention to the fact that, to avoid conflicts with other libraries (since it's not loaded by default in 1.16) jQuery will be loaded in [http://api.jquery.com/jQuery.noConflict/ noConflict()]-mode into <code>window.$j</code>.

You can use either <code>jQuery</code>, <code>$j</code> or something like the following to locally wrap-alias it:

<syntaxhighlight lang="javascript" style="overflow:auto;">
( function ( $ ) {
// Simple scope wrap, where $ is available as alias for jQuery.
// Code here will be executed immediately
}( jQuery ) );
/* or */
jQuery( document ).ready( function ( $ ) {
// Code wrapped in this function will be executed when the document is ready
// When the document is ready, jQuery calls this callback function with itself as
// first parameter, allowing you to locally alias it (e.g. as "$")
} );
</syntaxhighlight>

jQuery Migrate

The plugin jQuery Migrate helps developers to migrate from jQuery 1 to jQuery 3. The tracking task to remove these warnings and improve the underlying code is T169385.

Note that the stack traces are available together with the console log in modern browsers, to help to locate the origin of the deprecated function.

ResourceLoader

MediaWiki version:
≥ 1.17

As of MediaWiki 1.17 all resources are (or should be) loaded through ResourceLoader . The core modules are stored in /resources. There are no static minified versions anymore as ResourceLoader takes care of this when combining and optimizing all queued files. All code can assume that jQuery has already been loaded.

However, if your site skin was created prior to 1.17, ResourceLoader will not be loaded and jQuery will not be available.
