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

Hello,

i think this is the right site for you: https://www.mediawiki.org/wiki/Manual:Developing_extensions

I think, if i understand you right, you want to create a parser Extension? Then look, too, here: https://www.mediawiki.org/wiki/Manual:Parser_functions

To create a form you can use Html Class or HtmlForm class. To add a JavaScript file to the head, you can use addScriptFile in class OutputPage (https://doc.wikimedia.org/mediawiki-core/master/php/html/classOutputPage.html#a5ecdfe5c2253e36c580e0187c46d8c43). And the other is: read, read, read, learn, learn, learn :)

Hope that helps.
