[TYPO3] Adding onClick event to all internal links

[Loek Hilgersom]

Hi Zach,

We've been considering Javascript for this purpose but we already have quite a 
heavy set of client-side scripts. I'll check if the postUserFunc is an option, 
otherwise I may opt for adding the event to all links and just let javascript 
check whether the link is internal or not.

Thanks for your answer!
