Re: AJAX...

So, do you return XML and then convert that to HTML?  

Seems like extra work to me.  :)

Have you found any ways to debug AJAX such as view the
source returned on the page, etc?  IT stinks that you can't
even save the page with the dynamic information inserted
and see the *ML that was sent back from the app.  That's
the main thing that's holding me back on implementing it
more.

I had a huge shopping application for a customer set up
with AJAX but decided to go back to standard scripts
because I was finding debugging a pain.  Not that I insert
any bugs into code mind you.  :)

Brad,
Yes, Ajax, i.e., the XMLHttpRequest object supports
receiving "data". 
The "default" or "normal" or "usual" or "original" intent
was to return XML to
the browser, but it allows you to return anything,
including HTML, raw data,
Javascript or XML. 
I tend to use XML in my AJAX apps, but that' doesn't mean
everyone does or
should.
Sorry for being a be too specific, I tend to do that
lately. <tic>

Bob,

I've only used AJAX in a few projects now, but I've
always
returned HTML and I am curious as to this statement that
it
should be XML.

In fact, I found AJAX was what I've wanted for years.
 It's
fairly easy to convert your dymamic SSI to AJAX and make
the pages more seamless (as SSI was the closest to AJAX
that I could get before, and I use it for almost
everything).

AJAX really is just returning data to the page, so making
XML then converting that to HTML really seems like an
extra
unneeded step in most web applications, but I am
interested
in hearing the whos, whats and whys behind this
statement.
 :)

But, I'm shying away from AJAX the more I use it.  It
seems
to make debugging and error tracking, not to mention flow
a
little more difficult.  But it's still pretty cool.
