[Proto-Scripty] Re: $ function and IE
I actually user logic to solve your problem
if($('someid') != undefined)
{
$('someid').hide() // or whatever you plan to do
}
this cuts down on a function call of invoke and the CSS parser looking
for a CSS selector that matches

The easiest way around this is to write your code so it fails
gracefully. Either one of these will work:
$$('#noSuchElement').invoke(yourFunction);
or
var elm = $('noSuchElement');
if (elm) yourFunction();
The first one is my favorite, because it swallows any errors. If
you're saying that you're getting an error from IE just from trying
to use $('noSuchElement') all by itself, not actually trying to use
the return from that, then the first method is what I would advise.

Re: [Proto-Scripty] Re: $ function and IE
Yes... but in IE (in particular *old* IE) that lookup is very expensive.
Doing it twice isn't a big deal. But if it is in a loop and is being done
LOTS of times it can become a big deal. Basically, document.getElementById
is super slow in IE.
