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.

  • 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
