script works with IE, but not with FF

[JohnnyBeta]

I have a menu which stays in the middle of the screen when the page is scrolled down or up,
which is what I want.

It works with IE 6 or 7, but not with Moz or FF2.

Why does it not work with FF ?

Here's the script:

function setVariables() {
if (navigator.appName == "Netscape") {
v=".top=";
dS="document.";
sD="";
y="window.pageYOffset";
}
else {
v=".pixelTop=";
dS="";
sD=".style";
y="document.body.scrollTop";
}
}
function checkLocation() {
object="object1";
yy=eval;
eval(dS+object+sD+v+yy);
setTimeout("checkLocation()",10);
}

Thanks for any help.

I'll tell you why it doesn't work in FF if you can tell me why it DOES work in IE.

It probably doesn't work because that code looks like something out of the dark ages with all that old-hat browser detection from the late 1990s (well before FF was released).

Re-writing it to use modern DOM methods would be a far better bet.

If you need further help, perhaps posting the menu code in question would be helpful?

Hope this helps,

I had a feeling it was an oldie.
I'm not a programmer, you see. HTML and CSS is as far as my competence goes.

As for the menu code, what I posted is pretty much it.

There's some CSS bits, and an event handler like
onclick="loadStyleSheets(4,0)"
but no more.

I checked QuirksMode (which is waaaaay over my head anyways), and my very wild guess is that my script doesn't recognize FF2, or any FF's for that matter.

It also does not work with some older versions of Moz.

Instead of us breaking down the script for you to get it more cross browser compatible, it would probably be in your best interest to just go find a different script that suits your needs. Dan is correct, that script is a fossil. And when you're looking for a new cross-browser compatible script, a good rule of thumb is to not use anything that has a line in it like this:

if (navigator.appName == "Netscape") {

Browser sniffing is very clunky and unreliable.

So if there's no HTML portion at all, where are the menu items written to the page?
