PDF links to javascript?

[Mike Blackstock]

Is there a way to change the "textedit://uri"  mechanism in PDF point-and-lick links to point instead to a _javascript_ function in the webbrowser?

textedit:///path/guitar.ly:42:32:39

would instead be something like:
_javascript_:parent.handlePdfLinks("path/guitar.ly:42:32:39")

and the above would be executed on a click?

I've been looking around, but I know zilch about PDF documents; the closest
I got was this, which tells me it's do-able (I think)
