Where could I find an exhaustive list of javascript events defined by WooCommerce. ( Events like "woocommerce_variation_has_changed" )

On a hunt for the same I took a little dive into the JS source files.

Woocommerce Javascript events

Woocommerce Checkout JS events

$( document.body ).trigger( 'init_checkout' );
$( document.body ).trigger( 'payment_method_selected' );
$( document.body ).trigger( 'update_checkout' );
$( document.body ).trigger( 'updated_checkout' );
$( document.body ).trigger( 'checkout_error' );
$( document.body ).trigger( 'applied_coupon_in_checkout' );
$( document.body ).trigger( 'removed_coupon_in_checkout' );

Woocommerce cart page JS events

$( document.body ).trigger( 'wc_cart_emptied' );
$( document.body ).trigger( 'update_checkout' );
$( document.body ).trigger( 'updated_wc_div' );
$( document.body ).trigger( 'updated_cart_totals' );
$( document.body ).trigger( 'country_to_state_changed' );
$( document.body ).trigger( 'updated_shipping_method' );
$( document.body ).trigger( 'applied_coupon', [ coupon_code ] );
$( document.body ).trigger( 'removed_coupon', [ coupon ] );

Woocommerce Single product page JS events

$( '.wc-tabs-wrapper, .woocommerce-tabs, #rating' ).trigger( 'init' );

Woocommerce Variable product page JS events

$( document.body ).trigger( 'found_variation', [variation] );

Woocommerce Add to cart JS events

$( document.body ).trigger( 'adding_to_cart', [ $thisbutton, data ] );
$( document.body ).trigger( 'added_to_cart', [ response.fragments, response.cart_hash, $thisbutton ] );
$( document.body ).trigger( 'removed_from_cart', [ response.fragments, response.cart_hash, $thisbutton ] );
$( document.body ).trigger( 'wc_cart_button_updated', [ $button ] );
$( document.body ).trigger( 'cart_page_refreshed' );
$( document.body ).trigger( 'cart_totals_refreshed' );
$( document.body ).trigger( 'wc_fragments_loaded' );

Woocommerce Add payment method JS events

$( document.body ).trigger( 'init_add_payment_method' );

To bind listener to these events, use:

jQuery('<event_target>').on('<event_name>', function(){
    console.log('<event_name> triggered');

F. ex.

jQuery('body').on('init_checkout', function(){
    console.log('init_checkout triggered');
    // now.do.whatever();
  • Thank you for your answer, this is what I was looking for, I will come back here if I find other events.

    This is not working for me. I suspect my script needs to be made dependent on the woocommerce scripts, but I don't know what they're registered as.

  • @Badger what more specifically isn't working? Which page are you working on, and have you checked that the woocommerce scripts are being loaded?

    Nothing is logged to the console when I add something to the basket on the product page using the following code: jQuery(function() { // Product added to basket jQuery('body').on('added_to_cart', function(){ console.log('Item was added to cart'); }); }); The scripts appear to be loading. I have enqueued my script to be dependent on 'woocommerce'

    @Badger sorry I totally forgot to answer you. For others who might experience the same issue, by default Woocommerce does a full page reload upon add-to-cart event, hence the JS event never takes place. If you enable add-to-cart with AJAX in WC settings, you'll get the JS event too.

To find a complete list of all events (and stay updated on any new ones added) you can consult the .js files in the directory: /wp-content/plugins/woocommerce/assets/js/frontend

Below I report other events (in addition to @jgangso's answer):


  • hide_variation triggered when displayed variation data is reset
  • show_variation triggered when a variation has been found which matches all attributes
  • woocommerce_variation_select_change triggered when an attribute field changes
  • woocommerce_variation_has_changed triggered when variation selection has been changed
  • check_variations triggered:
    • when an attribute field changes
    • when reload variation data from the DOM
  • woocommerce_update_variation_values triggered when variations have been updated
  • woocommerce_gallery_reset_slide_position reset the slide position if the variation has a different image than the current one
  • woocommerce_gallery_init_zoom sets product images for the chosen variation


  • wc_fragments_refreshed triggered when refreshing of cart fragments via Ajax was successful
  • wc_fragments_ajax_error triggered when refreshing of cart fragments via Ajax has failed
  • wc_fragment_refresh refresh when page is shown after back button (safari)
  • wc_fragments_loaded triggered after the cart fragments have been loaded


  • country_to_state_changed triggered when the country changes from the select field
  • country_to_state_changing and wc_address_i18n_ready handle locale


  • wc-product-gallery-before-init triggered before initializing all the galleries on the page
  • wc-product-gallery-after-init triggered after initializing all the galleries on the page


  • price_slider_updated triggered after price slider updated
  • price_slider_create triggered after price slider create
  • price_slider_slide triggered after price slider slide

In addition to the full list references, you can go the interactive way and paste the below into your JS console and do the actions on the store, which you want to target, watch the console to see the effected events getting logged.

  "init_checkout payment_method_selected update_checkout updated_checkout checkout_error applied_coupon_in_checkout removed_coupon_in_checkout adding_to_cart added_to_cart removed_from_cart wc_cart_button_updated cart_page_refreshed cart_totals_refreshed wc_fragments_loaded init_add_payment_method wc_cart_emptied updated_wc_div updated_cart_totals country_to_state_changed updated_shipping_method applied_coupon removed_coupon",
  function (e) {

If you want to use the params in your code then here is an example

jQuery(document.body).on("wc_cart_button_updated", function (e, $button) {
