I am wondering what is the safest way to test if a variable is a
jQuery object. I am building a function where I want to be able to
pass in either the id of the form or the form object itself. The
current way I am doing this is
var $form = (form instanceof jQuery ? form : $('#' + form));
Is this the safest way that is not likely to change? Would I be
better offer wrapping this functionality into a function all by itself
so incase this does change, I only need it to change in one spot (plan
on building a complete UI type framework)?
