React Hooks Form : undefined values on submit
With v7 the usage of register changed as noted in the comments. If you still need to use v6, you have to write it like this:
function App() {
const { register, handleSubmit, watch, formState: { errors } } = useForm();
const onSubmit = data => console.log(data);
console.log(watch("example"));
return (
<form onSubmit={handleSubmit(onSubmit)}>
<input defaultValue="test" name="example" ref={register} />
<input type="submit" />
</form>
);
}
