Hiding CSS class from Netscape 4.x

[TravelMan]

I'm trying to do a show/hide of several elements on a page and can't
get it working in Netscape 4.x. All other Windows browsers are
working.

My elements all have the same class name. <div
class="myClassN ame">stuff</div>
I cannot use ID because I don't know how many will appear as they are
dynamic recordsets. Netscape seems to work OK with IDs but not CSS
classes.

For Netscape 4.x I have coded in my JavaScript:
document.myClas sName.visibilit y = "hide"; to hide it and
document.myClas sName.visibilit y = "show"; to show it.

My CSS for this function is:

<style type="text/css">
..myClassName {visibility:hid den;}
</style>

When I use the toggle I get this error: document.myClas sName has no
properties.

Any suggestions? Right now we are considering having standards-aware
browsers use client-side show/hide ( via
document.getEle mentsByTagName( ) ) and forcing Netscape 4.x to reload
the page, but would prefer to do it all in the browser.

Why not hide all CSS from Netscape 4.x and provide Structural Markup?
You can't support buggy browsers for ever...

Sorry, but I really doubt that the below is working with *any* user agent.

Is the `..' a typo? If not, remove one dot.

You cannot reference CSS classes like objects. Instead, iterate
through the collection of DIV elements (use document.getEle mentsByName,
document.getEle mentsByTagName or document.layers , depending on the DOM[1])
and change the `className' property of each element to the name of a
CSS class where the `visibility' property has the value of `show'.

Why is that better than using JavaScript to change the CSS property?
I'm just curious because I saw that method elsewhere [on the MSDN] and found
it quite interesting. Is it really better? You're still using JavaScript
either way.

Thanks,

Are those <div> elements positioned absolutely or statically with CSS?
If not forget about manipulating them with script as NN4 only makes
positioned elements available in its DOM.
If the <div>s are positioned then they should appear in
document.layers
and you can loop through document.layers
for (var i = 0; i < document.layers .length; i++)
document.layers[i].visibility = 'hide';
However if you wanted to check the class attribute of such a layer you
can't so you need to use other means to identify that a layer belongs to
a class, some way is to use an id attribute of the form
<div id="myClass01" >
then you can check
document.layers[i].id.indexOf('my Class') == 0
to find out whether a layer belongs to your class.

Of course it is doubtful whether Netscape 4 is still worth the efforts,
some static functioning HTML page should suffice for Netscape 4 users.

How do you get a handle on the className for a DIV when
getElementsByTa gName doesn't work in NN4.x? Is there another way to
get the className for a DIV or a layer?

It is called attribution _line_.

See above. The document.layers[...] collection allows for referencing
positioned layers.

Sorry, NS4-DOM seems not to provide a className property,
so referenceToLaye r.visibility is the only way.

Can you recommend any good books on the DOM and DOM scripting? I'm new
to using that and already am impressed by the power of what it offers.
Thanks.

just be sure you ensure your pages work in UAs without script support e.g.
googlebot.
