Question

How to create a yes/no/cancel alert box instead of ok/cancel alert box in Javascript?

Answer 1

You can't.

Instead, you can use a fake dialog library, such as jQuery UI Dialog.

These libraries create HTML elements that look and behave like a dialog box, allowing you to put anything you want (including form elements or video) in the dialog.
