That works--I had assumed that if I called something like $
("#myDiv:hidden").show(); when myDiv is visible, it would cause a
problem "object not found" problem since #myDiv:hidden" should return
nothing, and I then tried to call ".show()" on that "nothing" that was
returned.
In Java/C# I would get a NullReferenceException if I tried something
like this. That's where I do most of my development so that's what I
was expecting.
But I am left asking, why *don't* I get some kind of "object not
found" error?
