How to use JavaScript to show a confirm message?
A confirmation dialog box is mostly used to take user's consent on any option. It displays a dialog box with two buttons: Cancel.
If the user clicks on the OK button, the window method confirm() will return true. If the user clicks on the Cancel button, then confirm() returns false.
Example
You can try to run the following code to implement confirmation dialog box in JavaScript:
