Add $js->serializeForm()

serializeForm($options = array())
Serialize the form attached to $selector. Pass true for $isForm if the current selection is a form element. Converts the form or the form element attached to the current selection into a string/json object (depending on the library implementation) for use with XHR operations.

Options
•isForm - is the current selection a form, or an input? (defaults to false)
•inline - is the rendered statement going to be used inside another JS statement? (defaults to false)
Setting inline == false allows you to remove the trailing ;. This is useful when you need to serialize a form element as part of another Javascript operation, or use the serialize method in an Object literal.
