I recommend that instead of checking for browsers you check for what functionality exist on a certain browser :

if (document.all)
{
// code with document.all dom
}
else if (document.getElementById)
{
// code with document.getElementById
}

you can also use this to check if something exists :

if (window.innerHeight)
{
var winH = window.innerHeight
}

etc...

I seperate my browser checking code into three main families. ieDom, ns4Dom, and w3cDom. The advantage is that if the code checks wether or not a feature exists it doesn't need to be upgraded as often.

Does this make sense to you? Gary

I vote for xutopia's suggestion.
I would also add check-up for (document.layers) that corresponds only to NN4.x if you need it.

(document.all) is for IE4 only since IE5 and above "understand" getElementById.

(document.getElementById) is sufficient for IE5+, all Gecko-based browsers (Mozilla, Netscape 6.x, Galeon, etc) and Opera 5+.

If you want to know more about Opera identification, read this: faq216-1512

good luck
