Thread:Project:Support desk/I need html forms and Javascript in MediaWiki - Extension:CalcII doesn't work on newer MediaWiki Versions/reply (2)

Hello Florian,

thank you for the links and the hint with the classes. I now have the following code (where calculator.js has a function "delete_all) but get an error "delete_all" is null: '); $wgOut->AddHTML(' '); $wgOut->AddHTML(' '); } When using mediawiki classes, do I have to import them with "$wgAutoloadLocalClasses"? I already studied a lot of other extensions but didn't find out how to get it work.
