Thread:Project:Support desk/I need html forms and Javascript in MediaWiki - Extension:CalcII doesn't work on newer MediaWiki Versions/reply (11)

For me that seems false ;) But, i'm really silly :) To load a JavaScript Module for your extension you better use ResourceLoader (since MW1.17):

https://www.mediawiki.org/wiki/ResourceLoader/Developing_with_ResourceLoader

And then use: $out->addModules( array( 'ext.Calculator' /* or the equivalent name you give the resourceloader module */ ) );

Sorry for confusion :/
