Layer Visibility Based on Previous Link

Hello All:

Say I have a page that contains several layers, and I have many different
links to this page throughout my site. Is it possible to have the visibility
of a layer dependent upon the link that's used? For example, if you use Link
A, then the page will load with Layer A visible; if you click Link B, the
page will load with Layer B visible, etc.

This sounds like a job for SSI and a database........

You could create a URL parameter on the links and then write an IF statement
around the visible tag of the layer.

The exact code would depend on the server language used.

I think this can all be done on the client side without need of a serve
language at all. As has been suggested, have each link to the page with a
unique querystring appended to the url, and have the target page read the
querystring (location.search is a handy way to get at it) and have
conditional code on the page that sets the visiblilty of the layers based on
the value in the querystring.

Thanks for your help!

I'm not quite clear though, do you mean assign the URL a name? For example:

<a name="LinkA" href="the_page.htm">Link A</a>

then in "the_page":

<div id="LayerA" style="position:absolute;
if (Link A) visibility:visible; ....>

This is just basic html code and I'm not sure how to do what you're
suggesting.

Mick can tell you how to do this very easily with a bit of client-side
javascript, e.g.,

<a href="page2.html?a>Link for layer1</a>
<a href="page2.html?b>Link for layer2</a>
<a href="page2.html?c>Link for layer3</a>

where page2 parses the a, b, or c from the command line and show-hides the
appropriate layer.

Oh I see... I would have to write a JavaScript function.

Nothing's happening....

So I have the following in the body of my target page, pretty much as Mick
described:

<script language="JavaScript">
var thelayer= (location.search)? location.search.substring(1):"default";
MM_showHideLayers(thelayer,'','show')
</script>

I gathered from his posting that the variable declaration is supposed to be
in the head, but that created errors so I did the above.

There are no errors now, but either thelayer is not becoming "default", or
showHideLayers is not working.

I appended ?layerid to my links, but the target page still loads without
effect.

What am I missing?
