How can I add custom code to prevent someone from adding more than 1 item to their cart in Webflow?

To add custom code to prevent someone from adding more than one item to their cart in Webflow, you can follow these steps:

1. Open your Webflow project in the Designer.

2. Navigate to the page where your cart is located.

3. Click on the page's head tag element in the Navigator panel.

4. In the right-hand panel, go to the Custom Code tab.

5. In the Header Code section, add the following JavaScript code:

<script>document.addEventListener('DOMContentLoaded', () => {  const addToCartBtns = document.querySelectorAll('.add-to-cart-button');    addToCartBtns.forEach(btn => {    btn.addEventListener('click', (event) => {      const cartItemsCount = localStorage.getItem('cartItemsCount');            if (cartItemsCount && parseInt(cartItemsCount) >= 1) {        event.preventDefault();        alert('You can only add one item to your cart.');      } else {        const updatedCartItemsCount = parseInt(cartItemsCount || 0) + 1;        localStorage.setItem('cartItemsCount', updatedCartItemsCount);      }    });  });});</script>

This code uses JavaScript to select all the "add to cart" buttons on the page and adds a click event listener to each button. The listener checks if the user already has an item in their cart by checking a localStorage variable. If the user has one or more items, the code prevents the default behavior (adding the item to the cart) and displays an alert message. Otherwise, it increments the value of the cartItemsCount variable in the local storage by one.

1. Save and publish your project.

By adding this custom code, you will prevent users from adding more than one item to their cart in Webflow.

Note: This code assumes that you are using Webflow's default cart feature. If you are using a third-party eCommerce integration, you may need to modify the code according to the specific implementation.
