Question

I am developing an extension for Mediawiki which is based on another extension (developed in-house) that will not work above with a Mediawiki installation with a version superior 1.16.5 . I need to include javascript in pages belonging to a specific namespace and I cannot use the ResourceLoader http://www.mediawiki.org/wiki/ResourceLoader .

Does someone know if there’s a simple to do this? I need to include JQuery and Datatables for a custom rendering of the pages belonging to the namespace.

There are at least three ways to go about this.

The 1st approach is to edit the magic page MediaWiki:Common.js and add something like this:

if(wgNamespaceNumber == 0) { // NS_MAIN
  importScript('MediaWiki:MyScript.js');
}

You can place arbitrary javascript in the block, the importScript bit there is for executing JavaScript stored in a Wiki page but there are other ways to include JS on the fly as well (see eg. this question). See Manual:Interface/JavaScript for details of the MediaWiki side of things.

The 2nd approach would be to hack the PHP that produces the MediaWiki page to inject <script> tags depending on the current namespace, but that’s a bit more involved: you’d need to build a custom extension and hook it in at some appropriate point. The ParserAfterTidy hook looks suitable, see Hooks.

The 3rd approach would be to simply edit the skin and load the JS for every page in the wiki — is there a reason you don’t want to do this for every page? They’re cached anyway, so it’s only a one-time hit.
