Re: How do I create a web page that....

[Pete Helgren <Pete@xxxxxxxxxx>]

Charles,

There are tons of examples on the Web.  Bob produced one not too long 
ago ( http://www.mcpressonline.com/mc/.6b33f863 )

It depends how comfortable you are with HTML, Javascript and basic web 
concepts.  I found it pretty easy to build an AJAX application and put 
one together, last minute, for my Common presentation. I think you will 
find the server-side stuff the biggest challenge.  I did my stuff with 
Java Servlets but CGILIB or CGIDEV2 would be alternatives.  The "magic" 
with AJAX is that the mechanism for requesting and retrieving the server 
data is fairly well encapsulated in just a few Javascript methods so the 
real work is on the server side application that receives, processes and 
returns the data. There are plenty on this list that can help you with 
that.  AJAX is pretty straightforward.

I'd start with the server side routines that will take the data you 
submit, process it and return the "history" records.  At that point the 
AJAX side is pretty simple in calling the XMLHttpRequest and response 
methods.
