A little background: I need to wire-up some custom JavaScript to be launched
when the Submit button of my form is clicked. I now believe that the best
way to do this with Tapestry5 is to use the Event.observer for this purpose.
Unfortunately my knowledge of client-side javascript, scriptaculous, etc, is
limited, and I can't make this work. The issue seems to be that my form is
within a t:block that gets injected into a t:zone dynamically.
So, even if I do this in my JS file:
Event.observe(window, 'load', function()
{
Event.observe('formTranslator', 'submit', function()
{
// some onsubmit actions
});
});
this will fail, because apparently, the my form named formTranslator doesn't
exist at the point the document is loaded (the form gets reinjected into the
t:zone whenever a new object to translate is selected by the user). The
JavaScript error that I see in my JS console is this:
"element is null" -> scriptaculous/prototype.js Line:3936
I guess I somehow need to have the Event.observer called everytime the form
is reinjected into the t:zone, but how? Are my assumptions correct at all?
Thanks for any ideas in advance!
