Joe and Owen--

Thanks for the ideas!

It's a bit of the opposite goal to LibX, in that rather than having a title/DOI/whatever from some random site and wanting to get to  the full-text article, I'm looking at the use case of academics who are already viewing the full-text article and want a link that they can share with students.  Even aside from the proxy prefix, the url in their browser may include (or consist entirely of) session gunk.

I'll try a regexp and see how far that gets me. I'm a bit trepidatious about the way the DOI standard allows just about any character imaginable, but at least there's the 10. prefix. Am also considering that if DOIs also appear in the article's bibliography I'll need to make sure the javascript can distinguish between them and the DOI for the article itself; but a lot of this might be 'cross that bridge if I come to it' stuff.

(As may be jQuery... :-) )

I'd say yes to the investment in jQuery generally - not too difficult to get the basics if you already use javascript, and makes some things a lot easier

It sounds like you are trying to do something not dissimilar to LibX http://libx.org ? (except via bookmarklet rather than as a browser plugin).
Also looking for custom database scrapers it might be worth looking at Zotero translators, as they already exist for many major sources and I guess will be grabbing the DOI where it exists if they can http://www.zotero.org/support/dev/translators
