Re: RPG and AJAX was->RE: How do I create a web pagethat....

Just keep in mind that the "A" in AJAX stands for "asynchronous", and adding 
records to a file and refreshing the list on the screen doesn't require an 
asynchronous request / response.
 
The general idea of AJAX is making a request to the server and processing a 
response, in the background, without interrupting the current activity on the 
screen.  One of the best uses I've seen for AJAX was having the "onblur" event 
of a Zip Code field trigger an asynchronous request to automatically fill in 
City and State fields, while the user continues filling in other form data.
 
This isn't to say that I'd be against using AJAX to post database changes and 
update the list, but it's not clear to me how the added complexity would 
improve the user interface.
 
I just started using Yahoo's Mail BETA, which evidently is Yahoo's answer to 
Google's Gmail client, and I like the user interface, but when I.E. prompts me 
to debug JavaScript errors, a 680K Javascript file is presented in the 
debugger.  It's interesting to see that Yahoo Mail BETA uses AJAX extensively.  
But I ask myself, is all this JavaScript necessary?

Joe,

Good points, however in this case I do want the server to validate the
input and in fact return a few extra fields from the server.

Ajax seems to be a possible solution, or perhaps JSF and Java beans.

Thanks,
