I personally find it is pretty easy to use javascript with Zope.  Basically, 
if I want to use javascript (like mouse-overs), I create a dtml document 
containing the javascript I want

Then, I modify the "standard_html_header" method and add something like 
this:

<dtml-if js_Rollover_Insert>
  <dtml-var js_Rollover>
</dtml-if>

Then, whatever DTML document I want to insert the javascript code for the 
mouse-over (ie "index_html"), I add a property called "js_Rollover_Insert".  
The value is not necessary, I use "Yes" for clarity.

What then happens is that whenever that "index_html" is called, the property 
js_Rollover_Insert is added to the namespace.

Then, as Zope goes through the namespace rendering objects, you eventually 
hit standard_html_header.  Since the property js_Rollover_Insert is in the 
namespace, the <dtml-if> statement will evaluate to true and render whatever 
is in the object "js_Rollover".

Hope I haven't confused you...

Just as a side note, I started out using IIS/Delphi to write a web 
application for the LAN group I was in at the time.  I did a pretty good job 
of writing the site; however, once I discovered Zope, and got through the 
learning curve, I was able to rewrite the site in less than 1/2 the time it 
took me to write the CGI scripts/ISAP DLL's.  It was also a *lot* easier to 
go back and add functionality as it was needed.

If you are considering using a DB to store your data in, Zope will *really* 
outshine writing CGI/ISAPI in Delphi.


Hope this helps,

Andrew Williams
