T.J., one question for:
div = $("#errordlg");
if (div) { // Paranoia
div.remove();
I don't recognize this syntax: $("#errordlg");
This is different than (what I would typically write): $('errordlg');
Either TJ has been moonlighting in jQuery, or it's a typo. Here's
another way to write it that eliminates the if and also uses the hash:
$$('#errordig').invoke('remove');
This one-liner rolls up the conditional, since it takes an array
(which may be zero-length) and invokes the remove method on all of its
members. If there are no members, it's a noop.
