Topic awaiting preservation: does this work? (layers) (Page 1 of 1)

hi, I'm trying to pass layernames in a function, and that function will set the layer to visible

if (N)

	{

	var h="hide";

	var v="show";

	}

else 	{

	var h="hidden";

	var v="visible";

	}



function zeigen()

{

args=zeigen.arguments.length;

for (j=0;j<args;j++)

	{

		if (DOM)document.getElementById(zeigen.arguments[j]).style.visibility=v;

		if (I)	zeigen.arguments[j].style.visibility=v;

		if (N)	zeigen.arguments[j].style.visibility=v;

	}

		

}

for DOM it works, but for IE and N < 6? I'm asking, because I cant test it (don't have the old browsers anymore).
I would call the function like this:
zeigen("layername","secondlayer");

thank you in advance

It might work for earlier version of IE depending on what "zeigen.arguments" is.

IE 4 uses:
document.all['layerId'].style.visibility = value

But it won't work for netscape. Your setting:
YourReference.style.visibility = value

Netscape 4 doesn't use the .style bit. The NN4 property for visibility is:
document.layers['layerId'].visibility = value

Edit: Oh and you can still download Netscape 4 from www.netscape.com . But it's user stats are aparently below 1% nowadays so why bother.


You can also pass the visibility setting if coded the function more like this:

<BLOCKQUOTE><FONT face="Verdana, Arial">code:</font><HR><pre>function layerVisibility (id, vis) { // vis can be 'show', 'hide', or 'switch'

if (ns4) {obj = document.layers[id]}
else if (ie4) {obj = document.all[id].style}
else if (dom) {obj = doucment.getElementById(id).style}

if (vis=='show') {(ns4)? null : vis = 'visible'}
if (vis=='hide') {(ns4)? null : vis = 'hidden'}
if (vis=='switch') {(obj.visibility == ('visible'

oh, I had a typo in the code. the Netscape section should have been:
window.document.zeigen.arguments[j].visibility=v;

but, this won't work - what I actually assumed.

hm. The ID, do you mean the layer number, or just the ID (layername)?
e.g. will this work in NS 4?
if (ns4) {obj = document.layers[id]}

Is it possible to use the layer numbers instead of the names? (especially for DOM)

window.document.[arguments[j]].visibility=v;


will work for NN. ('layers' isn't necessary, btw.)
