如何在validate.js中訪問Reduce形式的reducer

Question

所以我想從我的reducer訪問一些數據，以便可以在我的validate.js中使用它進行我的redux-form驗證

const validate = (values, props) => {
  const errors = {};
     state.get('deposits').depositMethod // this is what I want to achieve
  return errors;
};

class VisaDeposit extends React.Component {
    render() {
        const {
            /* eslint-disable react/prop-types */
            handleSubmit,
            pristine,
            reset,
            submitting,
            selectedCard,
        } = this.props;

        return (
            <form onSubmit={handleSubmit}>
                <div className={s.newField}>
                    <div>
                        <Field
                            id="numberOnCard"
                            label="Card number"
                            name="numberOnCard"
                            component={renderField}
                            type="text"
                            placeholder="Card number"
                        />
                    </div>
                </div>
                <button
                    type="submit"
                    disabled={pristine || submitting}
                    className={s.submit}
                    >Submit
                </button>
            </form>
        );
    }
}

const selector = formValueSelector('accountDeposits');

const Form = reduxForm({
  form: 'accountDeposits',
  destroyOnUnmount: false,
  forceUnregisterOnUnmount: true,
  validate,
})(VisaDeposit);

const StyledForm = withStyles(s)(Form);

function mapStateToProps(state) {
  return {
    selectedCard: selector(state, 'selectedCard'),
  };
}

function mapDispatchToProps(dispatch) {
  return {
    loadRegisteredCards: bindActionCreators(loadRegisteredCards, dispatch),
  };
}

export default connect(mapStateToProps, mapDispatchToProps)(StyledForm);

如何訪問狀態，以便可以從我的減速器獲取數據？ 我嘗試研究文檔以及其他所有內容，但似乎找不到找到狀態的方法。

我嘗試使用this.state但它返回的值未定義。

您需要檢查這些values ，就像這樣-

const validate = values => {
  const errors = {};
  if (!values.numberOnCard) {
    errors.numberOnCard = 'Required';
  }
  return errors;
};

我建議瀏覽一下文檔
