So you mean the JavaScript should store the path to the component in the
hidden field and the form reads this out (if present) looks-up the
component and calls some (interface) method on the component. This would
be at least JavaScript wise the best solution - I don't know how older
browser behave when the name of the input field is changed.
A problem with this aproach is that Form.onFormSubmitted() is final and
I
don't realy know how to parse the path back because the component ids
can
be any string - AFAIK.
However also with the current aproach which stays with the 'normal' form
and button behaviour, you can bypass the Form.process().
In the following example there is a DropDownChoice with which you can
either reset or submit the form. You wouldn't need a roundtrip for that.
Anyway important is that the default fromprocessing is turned off, so
that
JSButton's onSubmit is called directly without involving the
form-component and that you can use the same aproach for any tag or
component in the page for any JS event.
class ChoiceForm extends JSForm {
String choice = "save";
String value = "";
public ChoiceForm(String id) {
super(id);
setModel(new CompoundPropertyModel(this));
add(new RequiredTextField("value"));
final DropDownChoice dChoice = new DropDownChoice("choice",
Arrays
.asList(new String[] { "save", "reset" }));
add(dChoice);
JSSubmit sub = new JSSubmit("jssubmit") {
protected void onSubmit() {
dChoice.updateModel();
if ("reset".equals(choice)) {
value = "";
} else {
process();//call Form's regular processing
}
};
};
sub.setDefaultFormProcessing(false);//!!
add(sub);
//add the JS to the choice onChange
dChoice.add(new AttributeModifier("onChange", true, new
Model(sub
.getTriggerJavaScript())));
}
//setter/getters
}
What I do not know is how to implement a WebMarkupContainer like
JSButton
so that it does not need a tag in the page-templat.
