Custom plus and minus quantity buttons in Woocommerce 3
问题 I’m building custom WordPress and WooCommerce theme and adding custom plus and minus buttons to Product page quantity field . The buttons do update quantity input's value and I also receive "Item has been added to your cart" notification (on Product page) when I submit Add to Cart. But the cart page doesn’t show any items, neither says the cart is empty. I can not work out which WooCommerce JS function I’m suppose to hook into, neither how to hook into it. Could I ask for help please?! Thanks
