[tsongwei]

I can't fiture out what's wrong with my code.
I wrote something like this:

if (document.layers){
alert("NN");
}else if(document.getElementById){
alert("IE");
}else{
alert("others");
}


It works with IE, but not for Netscape, does anyone know what's wrong in my code?

thx

document.getElementById works fine in newer versions of NN

Thanks

But what's best way to tell if the browser is IE or NN?

[brendandonhue]

whats wrong with
alert(navigator.appName)
?

But what is wrong with my code?

so if the browser is NN, do I get certain object by calling:
obj = document.layers("objName");
obj.value...........

Is this cool?
