I have been noticing a patters of posts where more and more people are claiming that Google is posting JavaScript forms. All of those posts, including this one, all have the same story. Basically, if you have a clean URL in the JavaScript, GoogleBot will try to explore that URL.
The same type of story spring up over the weekend at a WebmasterWorld thread. As you can tell by the thread, the JavaScript included some clean URLs, which GoogleBot extracted and explored.
Just be careful your JavaScript doesn't opening contain a method to delete your whole Web site.
