Back callbacks

vuEPG invokes a global or component callback for the BACK action.

Global callback

Configure at any time through setConfig:

const router = useRouter;

epg.setConfig({
  defBackHandler: () => {
    router.go(-1);
  },
});

Component callback

WARNING

• Active while the Vue component is Mounted/Activated, inactive when Deactivated/Unmounted.
• While a component callback is active, the global callback is not invoked.

Type

const onBack: (func: Function) => void;
