You can write parts of a page with JavaScript like this:
<SCRIPT LANGUAGE=JavaScript>
if (userName == "")
{ document.writeln("<H3>Welcome, new user.</H3>");
}else
{ document.writeln("<H3>Welcome, " + userName + ".</H3>");
}
</SCRIPT>
This code is generated before the page gets displayed to the user. If
you want to change things after the page is loaded, you can do it by
either altering the source of graphics
(document.images["imageName"].src="images/something.gif";) or changing
the text of a defined division of the HTML. That last option requires
that the user be using a browser that can handle DHTML, such as Netscape
4 or IE4. I forget exactly how to do it, but it can be done. If it's
something you want to try, do a search for DHTML tutorials and you'll
find examples.
