Hi Johannes,
I haven't used it, but something like below will move you in the right
direction:
(You might need to do something in the decorateScript method to
prevent the onclick from bubbling)
public class ConfirmationLink extends AjaxFallbackLink
{
public ConfirmationLink(String id)
{
super(id);
}
@Override
public void onClick(AjaxRequestTarget target)
{
if(null == target) {
setResponsePage(new AreYouSurePage(getModel()));
}
// else you know javascript works and they really want this
}
@Override
protected IAjaxCallDecorator getAjaxCallDecorator()
{
return new AjaxCallDecorator() {
@Override
public CharSequence decorateScript(CharSequence script)
{
return "if(confirm('Are you sure?')) { " + script + "};";
}
};
}
}
best,
jim
