如何访问类函数内部的状态？

Question

I need to access the redux state inside that function, so I can call Translator.init(data) wherever I want to use that. But I couldn't access the state like this. I'm not familiar with class components, What's wrong here?

    import { connect } from 'react-redux';
    import { createStructuredSelector } from 'reselect';
    import { makeSelectNumber } from './selectors';

      class Translator {
          init(data) {
            const sum = data + this.props.num
            return sum;
         }
    }

const mapStateToProps = createStructuredSelector({
  num: makeSelectNumber(),
});

export default connect(mapStateToProps)(Translator);

export const TranslatorService = new Translator();

Answer 1

Did you imported the correct selector?. You are importing makeSelectLocale and calling makeSelectNumber inside mapStateToProps?
