how to determine if dom element exists...?

[jschrock]

I've seen the command but can't for the life of me remember what it is... Basically looking for an expression that indicates the existance of whether a dom element exists. Its something like typdef or defined/undef or something.... It does not use null for example if (document.somthing == null) . It determenes whether an element exists and is not null. Can someone remember, thanks in advance...

sounds like 'undefined' is the word you are searching for

but you don't actually need to use that word most of the time, you can just say...

if ( document.someObject ) document.someObject.doSomething();

Yes, thanks you that's what I was looking for, although its good to know the alternatives as well....

typeof document.all == 'undefined'

Thanks for your help.....
