Talk:How to enhance wiki content with JavaScript

This howto is easy to understand also without js skill. but I had to change the js code (from MediaWiki:YourScript.js) as it is described here http://jsfiddle.net/7f9uko44/ (thanks to Krinkle from "mediawiki-l Mail-List"). I did the import code as recommended with importScript('MediaWiki:YourScript.js') (in MediaWiki:Common.js); and create a Template:HelloWorld and use that within pages but nothing happens. Do I forgot to activate or to allow js in mediawiki settings? In LocalSettings.php I set: $wgUseSiteJs = true; $wgAllowUserJs = true; $wgAllowUserCss = true; Is there any simple way to check js is running in my mediawiki?
