ajaxsubmitButton Question

I'm trying to use either blockUI or just put in an ajax loading gif when using ajaxsubmitButton but it doesn't look like there are any properties for doing something like this while the data is loading.

I've looked at the class reference to see if something exists but I don't see any properties other than the ajax() options and html() options.

I can do my own custom call if needed but wanted to see if there is something I might be missing.



Writing the js directly is perhaps better.

How can one make the contact page that comes with the skeleton skin use AJAX (i believe it currently uses a regular postback before validating right now).
