Don't post listings, post a URL to a working example. In your replies,
don't toppost and snip the post your are replying to.

My answer may be technically wrong, but it is pretty close to correct.

Netscape6.x/7.x/Mozilla 1.x does not have either document.all OR
document.layers! (document.all is MSIE only; document.layers is Netscape
4.x only)

Use document.getElementById() instead. This is more W3C/DOM correct.

Very very close, with one or two exceptions. document.all is not an MSIE
only thing. Opera has it, and one other browser has it (I dont recall
the name of it, it has both document.layers and document.all).

Also, Opera (in NN4 spoof mode) supports document.layers. See above for
document.all and document.layers.

Wow! Opera is better than I thought. And I have always thought it was
pretty good.

But why would anyone want to spoof the crap that is NN4?

I guess for the same reason they spoof the crap that is IE?

I think NN4 spoofing was put in way back when NN4 was still around, and
its left in for legacy's sake. You would have to ask in an Opera group
to be sure though.

Follow-up: set to comp.lang.javascript and the invalid
alt.comp.lang.javascript removed.

No, Opera doesn't support document.layers. It does however support the
non-standard document.all, but IIRC only in IE-spoofing mode.
