Hi again! I will try to describe what I am looking for. You know the common MediaWiki/wiki syntax: "{|" for example is a particular tag for the MediaWiki/wiki syntax. In HTML it is "<table>". I already recognize these two "languages" for programming/coding in a wiki: the MediaWiki/wiki syntax and HTML. But what languages are also possible that I can use in my wiki articles? You see this "dynamic news section": http://wiki.de.grepolis.com/wiki/Vorlage:Nieuws HTML and the MediaWiki/wiki syntax not suffice to create this. JavaScript is needed: http://wiki.de.grepolis.com/wiki/MediaWiki:Global.js So I already know three languages: MediaWiki/wiki syntax, HTML and JavaScript. But are there any further more? And how can I install JavaScript directly in my articles? Is there any way? Is there any book that contains these programming/coding languages, that can be used in a wiki? Do you understand my English? Probably not. :( Greets, GIC
