JSConfirmPanel

or JSAlertPanel

But if you know that delete is not allowed, why show the button/
link at all?
Performance! If you have 200+ rows and have to validate which
actions (possibly many) to allow, then the performance of the page
can be very slow. There are times when you have to weigh performance
vs UI completeness.
