help with function

[Key Bohn]

var NN4 = document.layers? true : false; //Netscape Navigator 4.x.
var IE4 = document.all? true : false; // IE version 4 and above.
var agent = navigator.userAgent.toLowerCase();

function display(flash) {
if (IE4) {
document.all[flash].style.visibility = "visible";
}
if (agent.indexOf("mac") != -1)
{
document.layers[flash].visibility = "hide";
}

else if(NN4) {
document.layers[flash].visibility = "hide";
}
}
This is being used to detect a user's browser and platform and show or hide
a layer containing a small flash movie depending. It's supposed to show in
IE for PC (which works) hide in Netscape for PC (also works) and hide for
IE MAcintosh. That last one does not work and it shows the layer. Can
anyone tell me why?

It works in Netscape 4, which is close to extinct (not close *enough*,
but close), but not in Netscape 6/7 (or other browsers based on Mozilla)
and hide for IE MAcintosh. That last one does

I have a guess, without having a Macintosh. You should also be aware
that the Safari browser is quickly gaining marketshare on the Macintosh,
and there is yet another browser wher your code doesn't work.

So, for the solution to your problem:
if (agent.indexOf("mac") != -1)
{
document.layers[flash].visibility = "hide";
}
IE doesn't have document.layers. This should be a copy of the IE line,
not the Netscape line, i.e.,
document.all[flash].style.visibility = "hidden";

(it is "hidden", not "hide", although both works in Netscape 4).
Why do you want your page to only work on IE in windows, when
it is fairly easy to make it work in all browsers?

}
if (agent.indexOf("mac") != -1)
{

Are you sure this is the exact spelling in the user agent? This is case-
sensitive. Mac != mac.
