This section shows the complete code of the shopping cart function of JavaScript development shopping cart.
By referencing the 4 JS files we created, all functions of the shopping cart are fully implemented on the page.
We created the list.php file for product display, the cookie.js file operates cookies, the
index.js file operates the list page, and the server .js operates local data module.
The cart.php file displays the shopping cart page, and the cart.js file operates the shopping cart.
Complete product list page list.php code:
