Definition and Usage
The confirm() method displays a dialog box with a specified message, along with an OK and a Cancel button.
A confirm box is often used if you want the user to verify or accept something.
Note: The confirm box takes the focus away from the current window, and forces the
browser to read the message. Do not overuse this method, as it prevents the user
from accessing other parts of the page until the box is closed.
The confirm() method returns true if the user clicked "OK", and false otherwise.
