Как сделать ajax обновление цены от количества товаров в мини корзине?

Question

[MisTFoR]

Здравствуйте!
Есть мини-корзина, хочу сделать обновление цены от количества товаров. Как это сделать?
Код мини корзины:

<?php
/**
 * Mini-cart
 *
 * Contains the markup for the mini-cart, used by the cart widget.
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/cart/mini-cart.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see     https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce\Templates
 * @version 5.2.0
