WebCore/html/HTMLFormElement.cpp:409
 +      // common browsers( sick! ) allow it be canceled.
both spellings are correct according to the dictionary.  probably
better to leave the existing code unchanged.

WebKit/chromium/src/WebFormElement.cpp:71
 +      return constUnwrap<HTMLFormElement>()->submissionTrigger() == NotSubmittedByJavaScript;
are you sure you don't want to expose an enum for the variety
of submission trigger types?

WebKit/chromium/src/WebFormElement.cpp:69
 +  bool WebFormElement::userSubmitted() const
I'm having a hard time understanding what this method name implies.  Is
this telling me that the user already submitted this form?  what happens
if the form is submitted multiple times (e.g., suppose it has a target
that corresponds to an IFRAME)?  what if the form is submitted once by
javascript and then once by user action?

what if the user clicks on a link, and some javascript runs, which
then calls form.submit()?  would that be regarded as a non-user
submitted form?

Done.

I thought about it, but decided not to over-engineer it for now (keeping it simple).  If a client needs to know more than just whether a user submitted the form, it's simple to add.

What do you think about wasUserSubmitted()? The value returned is for the last submitted form, so in the case you mention, if the client calls this method after the user submitted the form, it will return true.

From my reading of the code, this latter case will not be consider user-submitted.

OK

Sounds better.  The verb helps.
