Fellow Tapestry Users,
Hi!
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?
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.
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
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.
String key = $.ajax... //not sure how to call the URL in tapestry that
will get me the value
This is just about jQuery, not being related to Tapestry at all.
