Age Calculator

I created a DATEPICKER BOX and a TEXT BOX. I need that when a user inserts his birth date in DATEPICKER BOX automatically appears his age in the TEXT BOX. How can I do it?

Thanks 😀

This will need a JavaScript function to calculate the age, I think you can find something on google.
