Prevent ajax adding_to_cart conditionally #25759

// Trigger event.
$( document.body ).trigger( 'adding_to_cart', [ $thisbutton, data ] );
While generally simple products require no validation, there are times when plugins (like Name Your Price) might add fields that need validating, yet still want to take advantage of ajax add to cart.
In PHP we could use apply_filters to validate the product (and you do use that validating via woocommerce_add_to_cart_validation). I'd like to propose a JS alternative.
Describe the solution you'd like

Some kind of condition/flag that will prevent the add to cart ajax call from firing. I'm proposing the same thing in One Page Checkout and it could make sense if you both used the same condition.
