country onChange option (client)

hey there!


I'm currently integrating a payment page, and I want to use the country and state fields for displaying the price (VAT etc.).

I know that I can get the country and state fields from the callback page, but the issue is that I want to display a change in price whenever a user selects a different country inside the iframe.


I've tried every solution I found, but with no success and I know this might be problemtic and have security issues, but I wonder if there's a way to get a sort of onChange on this kind of event.


thanks in advance!
