- The main difference is that this does not allow arbitrarily adding hooks to any collection of elements.
- Modularizes val into a set of easily maintainable and conditional hooks.
- valHooks is placed at jQuery.valHooks
+ This could technically be extended, but I do not see it being used except in very rare cases since you can only apply valHooks to nodeNames and input types, and not a collection of elements as before. We could theoretically privatize valHooks taking it off of jQuery and only use it internally for our own convenience, but again, I do not believe this patch carries with it the dangers of the first proposal.
- Slightly improved performance of val on radios and checkboxes for browsers that support checkOn, given the conditional attachment of its hook.
