Window confirm()

Examples

Try it Yourself »

Confirmation box with line-breaks:

confirm("Press a button!\nEither OK or Cancel.");

More examples below.


Definition and Usage

The confirm() method displays a dialog box with a message, an OK button, and a Cancel button.

The confirm() method returns true if the user clicked "OK", otherwise false.


Note

A confirm box is often used if you want the user to verify or accept something.

A confirm box takes the focus away from the current window, and forces the user to read the message.

Do not overuse this method. It prevents the user from accessing other parts of the page until the box is closed.
