Custom JavaScript events

Advanced

Theme retirement Ira is no longer available on the Shopify theme store. Theme support and updates for current users will end after May 18, 2024. Learn more here.

We do not support code customizations. This guide offers a basic reference for advanced users familiar with HTML and CSS. Always test code changes on a duplicated, unpublished version of your theme. For assistance, we recommend finding a professional developer through Shopify Experts ↗ or Task Husky ↗.

For Ira, we've introduced custom events so developers can easily add their own functionality to the theme without needing to edit the theme's JavaScript files.

Use the custom-events.js file included in the theme to add all your custom scripts in one place and effortlessly hook into Ira's JavaScript.

For intermediate developers, Ira also includes an unminified**theme.js** file that can be enabled to edit the theme JavaScript directly.

Enable custom events

To enable custom events, you need to update the theme-globals.liquid to import the custom-events.js file that you'll be using for your scripts.

STEPS

  1. Open the theme-globals.liquid file in the Snippets folder.

  2. Find the useCustomevents variable and set it to true.

    

{% assign useCustomEvents = false %}
{% if useCustomEvents %}
  <script src="{{ 'custom-events.js' | asset_url }}" ></script>
{% endif %}

Add scripts to custom-events.js

Once you've enabled custom events, you can start adding your custom scripts to the custom-events.js file.

STEPS

  1. Open the custom-events.js in the Assets folder

  2. Add your scripts using the available exposed events or start from scratch and use this file to create something new.

Use exposed events

We've listed all exposed events within the custom-events.js file so you can easily use and edit them there.

The following exposed events are available to use as a blueprint to get started:

Item added to cart

This event fires when an item is added to the cart. The AJAX cart must be enabled for this event to be exposed. The product object is passed within the detail object.

document.addEventListener('flu:cart:item-added', function (evt) {
  console.log('Item added to the cart', evt.detail.product);
});

Cart updated

This event fires when the cart has been updated. The AJAX cart must be enabled for the event to be exposed. The cart object is passed within the detail object.

document.addEventListener('flu:cart:updated', function (evt) {
  console.log('Cart updated', evt.detail.cart);
});

Cart error

This event fires when an error occurs with adding an item to the cart. This error typically occurs when a product is unavailable due to insufficient stock. The error message is passed within the detail object.

document.addEventListener('flu:cart:error', function (evt) {
  console.log(evt.detail.errorMessage, 'Cart error');
});

Quick cart opened

This event fires when the quick cart is opened. The AJAX cart must be enabled for the event to be exposed. The cart object is passed within the detail object.

document.addEventListener('flu:quick-cart:open', function (evt) {
  console.log('Quick cart opened', evt.detail.cart);
});

Quick cart closed

This event fires when the quick cart is closed. The AJAX cart must be enabled for the event to be exposed.

document.addEventListener('flu:quick-cart:close', function () {
  console.log('Quick cart closed');
});

Product variant changed

This event fires when an a variant product is selected. A Variant selector block must be enabled on the product template or featured product section for the event to be exposed. The selected variant object is passed within the detail object.

document.addEventListener('flu:product:variant-change', function (evt) {
  console.log('Product variant changed', evt.detail.variant);
});

Product quantity updated

This event fires when the product quantity is updated. A Quantity selector block must be enabled on the product template or featured product section for the event to be exposed. The quantity and selected variant objects are passed within the detail object.

document.addEventListener('flu:product:quantity-update', function (evt) {
  console.log(
    'Product quantity updated',
    evt.detail.quantity,
    evt.detail.variant
  );
});

Quick view modal loaded

This event fires when the Quick view modal is opened. The 'Enable quick shop' feature (Theme settings > Cart) must be enabled for the event to be exposed.

document.addEventListener("quickview:loaded", function () {
  console.log("Quickview loaded");
});
