ajax chat over entire site

[Guest]

I have a ajax chat script but the page that i want to use it on is regular html so when i click on a link the chat either has to refresh or goes away. I need a way to laer the site so the ajax is always on top and the content can change.

 

I thought of doping frames but I cant find a way to put two ontop each other i dont think you can.

 

I thought of making the page ajax and using the xml request to get the page content that works but then I loose the back button. I started studying gmail and couldn't figure it out. Can someone tell me how the #inbox and #spam I have made the links like

 

<a href="#mainpage" onclick="javascript:changecontent('mainpage')">mainpage</a>

 

The back button shows the different pages but when i click then the url changes but everything just stays the same. Can someone help me figure out how to change the pages with the back button?

If im not misunderstanding your problem. Its extremely hard to see what you are talking about without actually seeing a example or the coding. However, if you used a z-index for your divs you can stack them up.

mmm, your issue sounds more like css/html, even though it's to incorporate ajax chat (js). As XoSilenceoX states, you should be looking at layers (<div>)...
