Yes, I think the AbstractDefaultAjaxBehavior could look to something like:
public void renderHead(Component component, IHeaderResponse response)
{
super.renderHead(component, response);
response.renderJavaScript("function boup(id) { " +
this.getCallbackScript() + " }", "my-script-id");
//TODO: <input type="checkbox" onclick="boup(10);" /> where (id = 10)
}
protected CharSequence getCallbackScript()
{
return this.generateCallbackScript("wicketAjaxGet('" +
this.getCallbackUrl() + "&id=' + id"); //warning, do not close script with
")"!
}
protected void respond(AjaxRequestTarget target)
{
final IRequestParameters parameters =
RequestCycle.get().getRequest().getQueryParameters();
int id = parameters.getParameterValue("id").toInt();
//TODO: do something with id
}
