Google is constantly trying new ideas to improve our coverage of the web. We already do some pretty smart things like scanning JavaScript and Flash to discover links to new web pages,...

Of course you will likely have links requiring JavaScript for Ajax functionality, so here's a way to help Ajax and static links coexist: When creating your links, format them so they'll offer a static link as well as calling a JavaScript function. That way you'll have the Ajax functionality for JavaScript users, while non-JavaScript users can ignore the script and follow the link. For example: <a href=”ajax.htm?foo=32” onClick=”navigate('ajax.html#foo=32'); return false”>foo 32</a>

JavaScript improvements Google has also been crawling some JavaScript for a while. Primarily, they’ve been extracting very simply coded links. As of today, they’re able execute JavaScript onClick events. They still recommend using progressive enhancement techniques, however, rather than to rely on Googlebot’s ability to extract from the JavaScript (not just for search engine purposes, but for accessibility reasons as well). Googlebot is now able to construct much of the page and can access the onClick event contained in most tags. For now, if the onClick event calls a function that then constructs the URL, Googlebot can only interpret it if the function is part of the page (rather than in an external script). Some examples of code that Googlebot can now execute include: <div onclick="document.location.href='http://foo.com/'"> <tr onclick="myfunction('index.html')"><a href="#" onclick="myfunction()">new page</a> <a href="javascript:void(0)" onclick="window.open ('welcome.html')">open new window</a> These links pass both anchor text and PageRank.

I'd say there's more then enough out there about google executing data on the fly.
