press escape if you do not want to clear form

I'm using Acrobat 2017 pro Windows

I have a button at the very end of my form that performs a form reset (button properties> actions>run a javascript> mouse up> reset form). Everything works fine.

Instead of immediately clearing the form, I would like to have a popup warning that all data is going to be cleared. If you want to continue press Ok. If not press escape.

Is this possible?

Thank you! I'm learning a lot from this forum.
