Create a button and edit the "Optional URL Redirect" parameters.

Set the "target is a" to "URL"

Set the the "URL Target" to :

javascript:confirmDelete('Are you sure you want to delete that record?','DELETE');

DELETE is the request value passed to the page. This can be used to conditionally trigger a process which will carry out the delete. In order to do this create a process and set the condition type to "Request = Expression 1" and type DELETE into the Expression 1 text box.




This technique can be used for any button where a confirmation is required from the user.
