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

You've nailed it on the head Nathan.  There are some definite uses where
AJAX makes a better fit. Too bad it has to be cornered into those specific
uses because of technology inadequacy. Though some users have come to accept
the browsers downfalls and are "willing to wait" for things to be
accomplished.

I tried Yahoo's Mail BETA also and like it much better than their standard
interface, but oddly enough the best feature I like is I don't get prompted
to log in every time I go there :-)

One site that has done quite the job of using AJAX is zimbra.com. They have
a live demo you can try out that is quite impressive.

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,

Charles Wilt
