Why don't you just add a listener to the 'submit' function of the form
using Prototype's Element.observe() or the similar function in jQuery?
Anyway, adding onXXX attributes to attach listeners to HTML elements isn't
recommended at all.

The form tag automagically renders a javascript handler for the onSubmit

onclick handler in MarkupConstants.WAIT_FOR_PAGE
<http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/MarkupConstants.html>
[2] described in [3].
How could I contribute my own javascript snippet to onSubmit attribute
of forms? How can I override this setting?
The problem is that this is no setting and therefore cannot be
overwritten.
One solution is to override the default JavaScriptStack of Tapestry and
provide another implementation of the onSubmit handler:
1. copy CoreJavaScriptStack
2. change tapestry.js in array to a modified copy in your project
3. contribute the overridden configuration
public static void
contributeJavaScriptStackSource(MappedConfiguration<String,
JavaScriptStack> configuration)
{
configuration.overrideInstance(InternalConstants.CORE_STACK_NAME,
MyCoreJavaScriptStack.class);
}
Has anybody a better idea?
