Hi,
Hi!
I imagine that if I wanted just a simple field on a page that updated
with a % then I would have Javascript make an AJAX get and obtain a
value from the server. However, as I'm a complete newbie to AJAX, an
example of how to do this would be extremely helpful.
The AJAX part itself is completely Tapestry-unrelated and there are many
examples in the Internet, maybe even in this mailing list archives. I
answered something similar yesterday. The AJAX Prototype documentation is
here: http://api.prototypejs.org/ajax/Ajax/Request/.
Example silly
questions: does my field have to be in a Zone?
No, as long as you write your own JavaScript code to do and handle an AJAX
request and then update the page DOM.
Also, would the % value updated by my process just be held in a @Persist
field?
Absolutely no. Just get the % value when handling the request. You don't
even need a field for that.
