Eine Lösung besteht darin, ein Mixin für die Funktion catalogAddToCart ajaxSubmit zu schreiben. Normalerweise sind die von Ihnen benötigten Daten hier nicht verfügbar. Dies kann jedoch durch Ändern des Checkout / Cart / Add-Controllers behoben werden, um die Daten zurückzugeben. Vollständige Lösung unten, derzeit werden nur die Daten angezeigt, die Sie für den Erfolg des Warenkorbs benötigen.
