Shopify Ajax Cart Callback

shop.js

// Create a global function that handles all cart-related JS
initCart = function (obj) {
    // Do all cart things here
    
    // If running as the ajax cart callback, an object is returned
    if (obj.is_visible) {
        // the cart is shown
    } else {
        // the cart was hidden
    }
};

// From your general JS file, run initCart() on your /cart page
initCart();

// In your theme.liquid file, initialize the ajax cart.
// Pass initCart as the callback function to onToggleCallback
// This will run the initCart function each time the cart is shown/hidden, passing an object back.
jQuery(function($) {
  ajaxifyShopify.init({
    method: 'drawer',
    onToggleCallback: initCart
  });
});

You're fantastic, thanks!
