$.fn.formValues;
Gets form values and creates a key=>value array of the found values.

What's new?
- Only does this for ENABLED elements.
- Keeps the same order of the form.
- Optionally adds the button which is clicked (marks that name with an 'x' in the list)

example: $('#frmLogin').formValues('oButton');



$.fn.update (PREVIOUSLY: $.update, so beware!!!!)
Calls sURL with sAction (method) and sends the aValues. Puts the results from that call in the jQuery object and calls fCallback if provided.

What's new?
- Renamed $.update to $.fn.update, since it is more obvious to call $('someJQueryObject').update(...) then $.update($('someJQueryObject'), ...). It's also more jQuery-ish
- Added the method you want to use, since i used post before, now you can select between either GET or POST.

example: $('someJQueryObject').update('sURL', 'sAction', 'aValues', 'fCallback');



$.fn.serialize
Calls the form's action with the correct method and the serialized values. Optionally adds the button which is clicked if you provide it. When there are results, the fCallback function is called.

What's new?
- The entire function

example: $('someForm').serialize('sButton', 'fCallback');
