It would be very useful if one of the developers could review the code,
so that we know if it's acceptable/desirable. Also, the JavaScript is
spread across the document in many places, and currently the library
does not differentiate between them. Is that OK? 

I would be glad to provide a patch. Would it be OK to put the code in
the getJS() method?
