Vinny,
Thanks for the response. Can you point me to an example where I can see what you're talking about in action?
thanks,

Question
dhtml layers with php
Hello,
I am downloading a few rss feeds using some php functions. As the feeds are
downloaded they are parsed into dynamically assigned layer id's. Once all
the feeds are downloaded and parsed. The first feed is displayed on screen
with links to display the other feeds when clicked upon. Clicking on a feed
link hides the current layer id and shows the layer id of the link clicked.
Pretty straight forward stuff I would imagine.
At any rate the problem I am experiencing is that the first layer id is
being positioned correctly but the subsequent layers are being positioned as
if they were below the first layer. I am explicitly placing all layers
at a 0,0 position relative to the container layer yet it still doesn't work.
To see what I am talking about click on this link
http://rise4peace.com/devi
Register, or Macromedia Dreamweaver links on the left hand menu.
The only reason I can see why this would not work is because the css has
already been loaded by the browser before all the layer id's have been
created. Even if this was the case I would think that when I assign the
layer location within the container it would still work.
Any suggestions would be greatly appreciated.
cheers,
devin

Hi devin:
I'll make it easier for you:
<html>
<head>
<script type="text/javascript" language="javascript">
function swapContent(divID, srcDivID)
{
document.getElementById(di
}
</script>
<style type="text/css">
</style>
</head>
<body>
<a href="#" onclick="swapContent('theD
<a href="#" onclick="swapContent('theD
<a href="#" onclick="swapContent('theD
<div id='theDiv'>default content</div>
<div id='lyr1' 'display:none'>layer 1 content</div>
<div id='lyr2' 'display:none'>layer 2 content</div>
<div id='lyr3' 'display:none'>layer 3 content</div>
content outside of the divs
</body>
</html>
With the above you don't have to change the way you get your source, simply:
1) add the function
2) change the menus so they reflect the above
3) change your current divs to stay hidden.
What I meant before essentially would involve placing your feeds into arrays or divs (as above) until they were needed. then the replacement would be approx the same.
Vinny
document.getElementById is version 5+ compatible.
if you need IE4:
function swapContent(divID, srcDivID)
{
var divObj1 = (document.getElementById) ? document.getElementById(di
var divObj2 = (document.getElementById) ? document.getElementById(sr
divObj1.innerHTML = divObj2.innerHTML;
}
notes:
1) no code for NN4 -- it would involve too much (absolute positioning; additional code) and unless you really absolutely need it...don't bother
2) the first line assigns to ver5+ browsers first, then IE4 -- (IE5+ recognizes doc..all, but so what :)
3) I threw out the second test in the second line because I know only ver5+ & IE4 are left
Vinny
Vinny,
I made the proper changes to my code and it's working really well.
The only other question I have is why would the scrollbars show when there's no content to be displayed?
http://www.rise4peace.com/
I checked through the source code and I can't see any place where this should happen. Is this something dhtml has a hard time handling?
many thanks,
devin

Hi,
The easiest fix would be:
1) have one layer
2) replace the one layer's innerHTML instead of having 3 layers and swapping their visibility.
