Re: [Proto-Scripty] $ function and IE

2011-08-30 Thread Walter Lee Davis

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.

around this?

That's very clever. Mostly I am surprised that only IE pukes on what I
assume to be a very common problem...

Anyway, thanks!

Actually, I lied. They ALL puke. Duh. It is just that IE is more obvious
about it. I guess everyone else already knew this. I am slow ;-)

You're welcome. I gave up being surprised what IE does somewhere back
in 1998.
