> Key: TAPESTRY-735
> URL: http://issues.apache.org/jira/browse/TAPESTRY-735
> Project: Tapestry
> Issue Type: New Feature
> Components: Framework
> Affects Versions: 4.0
> Environment: Tapestry 4.0-beta-12
> Reporter: Leonardo Quijano Vincenzi
> Fix For: 4.1
>
>
> I implemented a SubmitScript component that works in a similar way to
> LinkSubmit. The only difference is that it doesn't render any links, just the
> JavaScript function that submits a form and calls a listener
> It can be used on a page, like this:
> <span jwcid="[EMAIL PROTECTED]" action="listener:changeName" />
> And on the field...
> <input jwcid="[EMAIL PROTECTED]"
> onchange="ognl:components.changeName.href" />
> It only generates a JavaScript in the BODY component, like this:
> function changeName_id() {
> var form = Tapestry.find('Form');
>
> if (form.events.onsubmit_handler()) {
> Tapestry.find('changeName').value = "T";
> form.onsubmit = null;
> form.submit();
> }
> }
> And it'll call a listener in the component:
> public void changeName(IRequestCycle cycle) {
> .. // do something
> }
> This is mostly the functionality of Link, but far more flexible. I'm using it
> to attach listeners to 'onchange' and 'onclick' javascript events, and it
> could also be used to provide form submission to @DirectLink or @PageLink
> (LinkSubmit would get deprecated by this).
> This is already implemented, but it still has some app-specific stuff. If
> people are interested I can remove those things and submit it here.
