This looks pretty interesting. It does require the structure of the HTML to be very similar to the object, though. And I'm not thrilled that is uses the class name for a DOM node in the key/value pair. Why not define some "data-" attribute to read from?

EDIT: Looks like I posted without reading all of the comments in regards to the class name thing. I see some other people have mentioned it as well. It also looks like the author states that this isn't a hard requirement. I guess that would solve that problem at least.
