Retrieve the Router 6 useFetcher method in the form

Question

I have no choice but to call the getter's submit method in the handler. It's accessing the correct action method in the router, but I can't pass that method to the action, which is method='POST defined in the form. How do I access the fetch.Form method inside the handler?

const fetcher = useFetcher()

const handlerLogin = useCallback(async () => {
  console.log(fetcher.formMethod) //-> outputting undefined
  fetcher.submit({ value: 'social' }, { method: fetcher.formMethod })
},[])
    
return (
  <Card className={styles.loginCard}>
    <fetcher.Form method='POST' action='/'>
      ..............

Answer 1

Try this solution, passing the method to the handlerLogin function:

const fetcher = useFetcher();

const handlerLogin = useCallback(async (formMethod) => {
  fetcher.submit({ value: 'social' }, { method: formMethod });
}, []);

return (
  <Card className={styles.loginCard}>
    <fetcher.Form
      method='POST'
      action='/'
    >
      {/* other parts ... */}
      <button onClick={() => handlerLogin(fetcher.formMethod)}>
        Submit
      </button>
    </fetcher.Form>
  </Card>
);
