JavaScript confirm box with custom buttons

Question

Can I write a custom confirm box in JavaScript that, instead of the default OK and CANCEL button, shows a SAVE and DELETE

Answer 1

Not with the native JavaScript confirm box. You could use one of the many JavaScript UI components that emulate modal dialogs to do this instead.

Here's an example: https://jqueryui.com/dialog/#modal-confirmation

I've never used this so use at your own risk.
