Problem with getting the doc

[Clemenza]

Hello,

I use the following javascript code, which works well in IE and Opera,
but doesn't work with Firefox and Mozilla.

I always get an error "doc is not defined" when try to run code
eval(doc + layerName + sty + ".left = " + (eval(FromLeft) + 15))

Before I setup the doc variable as this:
var ie = document.all ? 1 : 0
var ns = document.layers ? 1 : 0
if(ns){doc = "document."; sty = ""}
if(ie){doc = "document.all."; sty = ".style"}

Any idea?

Thanks!

var ie = document.all ? 1 : 0

Internet Explorer stuff that Opera and Mozilla support - but Mozilla only
very recently introduced support and returns false to document.all to
discourage its use. You only need this if you need to support versions of
IE older then 6.

var ns = document.layers ? 1 : 0

Netscape 4 specific code. Support dropped after the 4.x series.

It doesn't "work well" in IE or Opera, you just think it does.

I always get an error "doc is not defined" when try to run code
eval(doc + layerName + sty + ".left = " + (eval(FromLeft) + 15))

Why are you using eval when you don't need it?
Had you bothered reading the group FAQ before posting you would have,
undoubtedly, found this section:

Before I setup the doc variable as this:
var ie = document.all ? 1 : 0
var ns = document.layers ? 1 : 0
if(ns){doc = "document."; sty = ""}
if(ie){doc = "document.all."; sty = ".style"}

Geeeez....
Ummm, you should read that FAQ, especially section:

Any idea?

Trash your code, buy a book, and start over.

Thanks!

Welcome.
