How to checkout on Modx (minishop2) via Ajax?

Question

MODX

Good afternoon!

I made a website where the shopping cart and the checkout form appear in a pop-up window on any page. All this works, loads and orders are sent well.

But when placing an order, the page reloads and there is no message "Thank you for the order" and "?msorder=34" is added to the url

How to make this order form via ajax - without reloading the page?
And how to remove the order parameter in the url ?
