Why don't you do this check on the page you are submitting to? If they
selected delete, you can display the item with another set of buttons to
Confirm or Cancel the delete.

This method has two big benefits. First, they get the option of viewing
whatever it is that they are deleting, so they don't accidentally delete
something because of a typo. Secondly, it will work for non-JavaScript
people.

This should be pretty simple if your posting to the same page, you'll just
have four if blocks. One if nothing is submitted (display form), 1 for
Delete button (show confirm page), 1 for Delete Confirmed (delete record)
and 1 for Edit record.
