Javascript confirm box inside PHP Echo function
提问by user3156271
I have a link inside PHP Echo function called "Delete". When user clicks on it, the delete.php page is called and the selected book is deleted from the database. So, I would like to insert a confirmation box asking user if he is sure to delete the book but I don't know how to do it.
