A guestbook is not something what I call interactive.
No, JavaScript can't do it (to save datas).
But JavaScript can call a file on server that can do it.
Ask Google : XMLHttpRequest
In "normal" JavaScript
you can program some actions looking like interactivity
(small game, diaporama, questions and answers, ... )
HTML is interactive : you click ... something happens

Why have people fallen into the trap of thinking that the XMLHttpRequest
Object is the answer to all questions when it rarely is? You can send
data to the server with a simple new Image() and set it's src property
as shown in the group FAQ. After the image has loaded you can redirect
to an updated view of the guestbook page.

I think a lot of people hear Ajax and think one of two things:
Server interaction
DHTML
Of course, one of those is a flawed perception.
Anyway, I still prefer to use FAQ 4.37 ( http://jibbering.com/faq/index.html#FAQ4_37 ) if
JavaScript is available.
The object trick (FAQ 4.34) just seems weird to me.
Also, would it help if XHR was not mentioned alongside FAQ 4.34? The way I read it is
that you have two options, set a new Object to handle your script or use an XHR.
Of course, this may be the desired effect. *shrugs*

because it's tooooo cooool ! :-)

Way of doing reserved to grand fathers !
too much easy,
not enough exiting,
not enough problems with cross domains,
and so on :-)
I think some browsers flash between old an new page,
and it's smoother when you just innerHTML a div.

I've been using pylab's plot function, but I'm finding it a bit
cumbersome.
It works, but if I switch from the interactive window to the plot window
and back, the plot window gets trashed.
