Thanks for all your advices.
$$('#pleaseWait').invoke('hide');
I do like this one, even if I am not sure why it would be a bad
practice to have failsafe functions (I said functions, not
methods :o) ).
It is common in C++ to check if a pointer is null before freeing it. I
don't see any
if($('pleaseWait')) $('pleaseWait').hide();
This is a classic coding issue. I disagree with you - in PHP I have
strict warnings on all the time so I'm always testing whether a
variable is set before accessing it. It's just a much safer way to
write code.
