您应该使用yup 和@hookform/resolvers 进行验证定义以便轻松配置它。

  const formSchema = Yup.object().shape({
    password: Yup.string()
      .required("Password is required")
      .min(4, "Password length should be at least 4 characters")
      .max(12, "Password cannot exceed more than 12 characters"),
    cpassword: Yup.string()
      .required("Confirm Password is required")
      .min(4, "Password length should be at least 4 characters")
      .max(12, "Password cannot exceed more than 12 characters")
      .oneOf([Yup.ref("password")], "Passwords do not match")
  });

const {
    register,
    handleSubmit,
    formState: { errors },
    reset,
    watch,
    getValues
  } = useForm({
    mode: "onTouched",
    resolver: yupResolver(formSchema)
  });

并将register 调用更改为仅包含归档的名称。

<input
    ...
    ...
    {...register("password")}
></input>

<input
    ...
    ...
    {...register("cpassword")}
></input>
