I'm working on a page that dynamically changes many form elements.
Because of the way that different browsers style disabled or readonly
text inputs, I'm swapping the input with a span that displays more
consistently. I don't need to submit those fields. However, when I do
this the affected element's ID does not change. There are also some
other cases where a control may change from a free text input to a
select menu and vice versa, but again with the same ID.
If there a way for me to figure out what the type of element for a
matched ID? For example if
$("#foo")
matches
<input id="foo" ...>
I'd like to know it is an input, but if
$("#foo")
matches
<span id="foo" ...>
I'd like to know it is a span?
