Netscape compatibility

Hi,

I need help : I found the simplest and most precise way to open and close
submenu layers. it works perfectly with IE, but for some odd reason NS won't
recognize it.

Can anyone tell me why ?

And is there a way around the problem ?

I really like the elegance of this code and would like to keep using it.

Thanks in advance.

Leaving out the question of the code elegance... I feel you came here for a
quick-n-dirty solution and not for a JavaScript lessons:

<script language="Javas cript"`>
<!--
function Pop(name){
document.getEle mentById(name). style.visibilit y='visible';
}

function Wop(name){
document.getEle mentById(name). style.visibilit y='hidden';
}
//-->
</script>

WHY??
Because document.all is an Explorer's proprietary collection, other browsers
do not support it.

LATER MAY LOOK HERE:
http://www.dynamicdrive.com/dynamicindex1/index.html
(of course there are many similar places with even better code)

Yes. documemt.all is IE. Here's a test for Netscape 6 and above I believe:

ns6 = (!document.all && document.getEle mentById);
//ns6 = true if Netscape 6+

Netscape 4 is this:

ns4 = (document.layer s);
//ns4 = true if Netscape 4

ie4 = (document.all && !document.getEl ementById);
// ie4 = true Internet Explorer 4

ie5 = (document.all && document.getEle mentById);
// ie5 = true Internat Explorer 5 and up

I'm not sure how to integrate Firefox and Opera in this scheme.

Finally yes the scripting is fine for IE. You might consider fixing the CSS. Attributes are all lower case.
Also the relative ../images may be able to change to /images. The trouble is that in new Microsoft web
servers they have disabled relative adddressing without overhauling the new security relative addressing will no
longer work.

Browser detection, whether by interpretation of the user agent string, or
object inference, is fundamentally flawed. You don't *need* to know what
browser you're using, just what it's capable of doing.

Obviously you haven't read FAQ entry, 4.26.

You don't.

The FAQ, and links to it, are posted three times a week. It exists in the
signatures of several regular posters, and is mentioned plenty of times in
responses to posts.

You've posted to this group longer than I have. I shouldn't need to tell
you where to find the article.
Actually this came from soneone else on the Internet it is not mine.
So?
In any case how is it flawed?


It isn't reliable and can, in some instances, entirely fail to identify
the intended browser. Furthermore, scripts based on this technique often
fail to work, or take advantage of new features, in future browser
versions.

That also matches Opera 6 (unless identifying as IE) and Opera 5, and
possibly also Safari and Konqeror (unless they decided to support
document.all as well).
Netscape 4 is this:

ns4 = (document.layer s);
//ns4 = true if Netscape 4
Also matches OmniWeb.
ie4 = (document.all && !document.getEl ementById);
// ie4 = true Internet Explorer 4
Also matches WebTV.
ie5 = (document.all && document.getEle mentById);
// ie5 = true Internat Explorer 5 and up
Also matches Opera 7, and Opera 6 when identifying as IE.
I'm not sure how to integrate Firefox and Opera in this scheme.


FireFox is based on the Mozilla project, just as the Mozilla Browser
Suite and Netscape 6+. They act identically.

Opera 7 is not distinguishable from IE 6 using only document.all and
document.getEle mentById.
Since there are many different browsers, and always more than an
author expects, trying to recognize specific browsers is rarely
a good idea. Because some people have tried doing it anyway, and
have made pages that refuse to show themselves to some browsers,
the users of those browsers frequently make their browser detect
as another one, making detection even more impossible.

If the existence of document.all/document.getEle mentById is releveant,
because script is going to use those specific properties, then it
makes sense to test for their presence. In that case, it doesn't
matter what browser it is anyway.

well here we go. I went to the link and looked under 4.26: Here was their example that I assume is the way it is supposed to be done:

if (document.getEl ementById &&
document.getEle mentById('el') &&
document.getEle mentById('el'). style ) {
// We know that this browser supports getElementByID and has
// a style object, so we can set a style property.
document.getEle mentById('el'). style.color="re d";
}

That looks pretty familiar.

I didn't see anything about fundamentally flawed of what I presented earlier. Oh well thanks for the liink.

It's a way. It could be made more efficient by saving the references
obtained rather than repeated look-up.
if (document.getEl ementById &&
document.getEle mentById('el') &&
document.getEle mentById('el'). style ) {
// We know that this browser supports getElementByID and has
// a style object, so we can set a style property.
document.getEle mentById('el'). style.color="re d";

That looks pretty familiar.

Hmmm.
