Perhaps. Ideally I'd want something like preventDefault() on a DOM submit event.

If I connect to decide-policy [1] and then call
webkit_policy_decision_ignore [2], then the submit-form signal is not
emitted, so I can't get the submitted data. (Actually, I can with a
hack: ensure that all forms have method=get, and parse the query
string out of the WebKitURIRequest. I'll probably go that way if I
don't find a better solution.)

By the way, another problem I have with the API is that
webkit_form_submission_request_get_text_fields [3] only seems to
return the values of text inputs (type=text, type=password etc., but
not type=checkbox or select). Is this intentional?
