Измените местоположение параметров доставки оплаты WooCommerce, разрешив обновление ajax

Недавно я переместил часть формы оформления заказа (wc_cart_totals_shipping_html()) из review-order.php в form-billing.php в своей настройке WooCommerce. Раньше я использовал jQuery('body').trigger('update_checkout'); в form-shipping.php для динамического обновления методов доставки, но в form-billing.php это больше не работает.

Может ли кто-нибудь подсказать мне, как динамически запускать обновление методов доставки (wc_cart_totals_shipping_html()) в form-billing.php с помощью jQuery или AJAX? Я хочу, чтобы раздел доставки обновлялся в зависимости от изменений платежных реквизитов (например, выбора страны).

<?php if ( WC()->cart->needs_shipping() && WC()->cart->show_shipping() ) : ?>
        <?php do_action( 'woocommerce_review_order_before_shipping' ); ?>
        <?php wc_cart_totals_shipping_html(); ?>
        <?php do_action( 'woocommerce_review_order_after_shipping' ); ?>
    </div>
<?php endif; ?>

Недавно я переместил часть формы оформления заказа WooCommerce, связанной с доставкой (wc_cart_totals_shipping_html()), из form-shipping.php в form-billing.php в шаблонах WooCommerce моей темы. Раньше я использовал jQuery('body').trigger('update_checkout'); успешно в form-shipping.php для динамического обновления методов доставки на основе действий пользователя
