link with confirm dialog
Hi all,
how can I change the code so that the confirm-dialog is called when the #onClick method is executed and not at constructor-time?
I would like to change the dialog text based on some runtime variable.
Thanks, Chris
Link link = new AjaxFallbackLink("link") {
@Override
public void onClick(AjaxRequestTarget target) {
setResponsePage(new Page());
}
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes attributes) {
super.updateAjaxAttributes(attributes);
AjaxCallListener ajaxCallListener = new AjaxCallListener();
ajaxCallListener.onPrecondition("return confirm('...');");
attributes.getAjaxCallListeners().add(ajaxCallListener);
}
}
};

Hi,
'confirm' is a JavaScript method.
It is executed *before* the Ajax call that would lead to execution of
AjaxFallbackLink's onClick().
If 'confirm' returns false then the Ajax call won't be made at all.
To accomplish what you need you have to introduce a step in the middle.
When the user clicks on the Ajax link you have to open a dialog/modal
window with your question and buttons OK/Cancel. If OK is clicked then go
to page Page, otherwise do nothing.
