Bug 90111 – Cleanup HTMLFormCollection

• Component: Forms
• Status: RESOLVED FIXED

[Ryosuke Niwa]

As the comment at the beginning of HTMLFormCollection.h this entire class is a giant hack, and indeed the class is filled with questionable code.
Clean up some of that mess first so that we can do more refactoring later.

Updating m_cache.current here made no sense. In fact, I bet you can find a test case where this introduces a bug using the Objective-C binding.
e.g. collection.item(0); collection.namedItem('blah'); collection.item(0);
The second call to item() returns the element with id/name 'blah'.
Unfortunately, ES5 binding uses namedItems so we can't add a layout test for it.

Typo, enamed.

Maybe someone should rename isEnumeratable() this to isEnumerable() someday.

I've figured out a way to write a WebKit API test so I went ahead and landed it with it. Fixed the typo in http://trac.webkit.org/changeset/121479.
