How to change the appearance of the shopping cart in the storefront theme?

Question

WordPress

Good day! Can you tell me how to change the appearance of the shopping cart in the storefront theme?
I go into the storefront/inc/woocommerce/storefront-woocommerce-template-functions.php theme file and try to fix the storefront_cart_link() function to display the cart differently on the page, but nothing changes, even the banal characters "(" and ")" inserting fails, they appear for a second and then disappear or are overwritten somewhere, what could it be?

Answer 1

It uses a WooCommerce cart, which is also updated by Ajax (hence the overwrite). There is a templates folder in the WooCommerce plugin folder. Copy it to your theme folder and name it woocommerce. And there already edit all the templates as much as you like. If I understand correctly, you need a template templates/cart/mini-cart.php

Answer 2

All observers for changes in the users array are registered in observers, so when adding / removing (possibly also during other operations) an element of the array, the usersAddedOrRemoved method is called, which contains information about changes: indexSplices - an array of objects that have the following properties: index, removed, addedCount, object, type.
In this code , the changeRecord.indexSplices.forEach(function(s) {value of s contains the properties listed above, i.e. this is an element of the indexSplices array (read the forEach documentation if it's not clear https://developer.mozilla.org/ru/docs/Web/JavaScri... )
