Tapestry AJAX call on submit
Fellow Tapestry Users,
I have a form that when submitted needs to
make a call to an external service (calling a URL that will return a
value of type string) which i will then add to the form data and do the
actual submit.
What is the best way to handle this in Tapestry?
So for e.g
@Log
Object onSubmitFromTestForm() {
//need to make some form of AJAX or javascript call here to the URL provided
//that will return a value
String key = $.ajax... //not sure how to call the URL in tapestry that will get me the value
.. continue with regular process with key obtained and do the submit
return ConfirmedPage.class;
}
Thanks for your help!

Try a Tapestry AJAX Form with two Submits: one visible and one hidden. Add JavaScript that listens to the click of the visible submit, stops the event propagating, does the call to the external service and, on success, sets the value of the form field (which might be a hidden field) and clicks the hidden submit.
Here's a standard AJAX Form:
T5.4: http://jumpstart.doublenegative.com.au/jumpstart7/examples/ajax/form
T5.3: http://jumpstart.doublenegative.com.au/jumpstart/examples/ajax/form
Here's some JavaScript that listens to something:
T5.4: http://jumpstart.doublenegative.com.au/jumpstart7/examples/javascript/robust
T5.3: http://jumpstart.doublenegative.com.au/jumpstart/examples/javascript/robust

Did you miss my response? Much better than trying to handle the final submit yourself. Here it is again...

Thank you for that clarification again.
So just to be clear, once i have javascript handle the call to the external url, and process the data. Once i do form.submit() in javascript, my OnSubmitForm event in Tapestry will still get triggered?

You're still confused here. The Tapestry submit event is triggered by the
web server receiving the form submission, so you do *not* want to invoke
the external URL as part of the Tapestry submit event. You want to do
stuff *before* the form submission, so before the Tapestry submit event.
> So was looking for a way using AJAX and JavaScript to do it.
So you're asking in the wrong place. This is a Tapestry mailing list and
your question isn't Tapestry-related. It's a pure JavaScript question.

Sorry about the confusion and I appreciate your feedback .
I would like to invoke the external URL as part of the onSubmit event. So before the form is submitted . So was looking for a way using AJAX and JavaScript to do it.

In the same way you'd do without Tapestry: using some JavaScript to make
the call to the external service, then changing some field values to
reflect the result, them programatically submitting the form.

I'm confused: do you want to call the external service before the form
submission, through AJAX and JavaScript or after (onSubmit is after the
form submission, looking at the HTML side, as it's processing the form
submission), server-side. If after (server-side), just use something like
Apache HttpClient to do the request. This isn't affected by being done in
a Tapestry page or component class at all.

This is just about jQuery, not being related to Tapestry at all.
