Trim Trailing Zeros in WooCommerce Product Addons Price Display

Perhaps you are using the woocommerce_price_trim_zeros as suggested in this thread: https://wordpress.org/support/topic/about-price-displaying/ and you have noticed that filter has no effect on product addon price displays. This is due to an unresolved issue with the accounting.js library here: https://github.com/openexchangerates/accounting.js/issues/93

There is a workaround, however. The workaround requires a bit of JavaScript trickery to achieve. Fortunately, Product Addons has a custom event registered named updated_addons so some custom JavaScript can be created to trim the trailing zeros when that event is triggered. The JavaScript would look something like this:

If you’re unclear on how to get that bit of JavaScript loaded on your site, this can be done with the WordPress wp_enqueue_script() function. And if that still isn’t clear, I have created a very basic plugin that can serve as an example. Click here to download.
