Currently our Ajax extensions ([[Extension:SimpleForms|SimpleForms]] and [[Extension:Livelets|Livelets]]) use the [http://mootools.net MooTools] JavaScript framework. The most commonly used ajax process is to post a form to the server and have the response directed to the ''innerHTML'' property of an element having a particular ''id'' attribute. The ''mootools'' syntax for achieving this functionality is:
 
−
<js>
 
−
$('form-id').send({update:$('target-id')})
 
−
</js>
 
−
where ''form-id'' specifies the ''id'' attribute of the form whose content we want to send to the server, and ''target-id'' is the ''id'' attribute of the element the servers response should be appear within (usually a ''div'' element).

I'd like to have a simple code snippet for achieving that same basic ajax requirement with the native MediaWiki components rather than depending on a third-party framework.

It says in [[MW:Manual:Parameters to index.php]] regarding ''action=ajax'', that a PHP function in ''AjaxFunctions.php'' will be executed. That module contains ''wfSajaxSearch'' (search for articles of title similar to a search term) and ''wfAjaxWatch'' (watch/unwatch a page). Note that ''$wgUseAjax'' must be set to true and the only callable functions are those in the array ''$wgAjaxExportList'' (which is also modified by the variables ''$wgAjaxSearch'' and ''$wgAjaxWatch''). In addition to ''action=ajax'', there is ''rs'' (the function name, e.g. ''rs=wfSajaxSearch''), ''rsargs[]'' (an array of arguments to the function (e.g., rsargs[]=abcd passes the abcd string to the function). There is a JavaScript function for calling this action in ''ajax.js''.
