I understood, that about a year ago, Google stated that they are able to
extract URLs out of some of the javascript. Note that they don't interpret
JavaScript as a language, but are able to recognise some things.

I don't use JavaScript on my own sites (or: not on pages I have in Google),
so I haven't looked into this.

My guess it's mainly to follow:

<a href="javascript:ShowWindow('http://example.com/')">bla bla</a>

links.
