reactjs - 如何获取Reactjs中单选按钮(react-radio-buttons)的值？

Question

如何获取单选按钮的值，如果我在RadioGroup中调用updateRadioButton，会导致错误。我需要使用(react-radio-buttons)在控制台中打印为男性或女性。单选按钮打印正确，但我无法获取该值。提前谢谢您。

 class CreateUserComponent extends React.Component {
        constructor(props) {
        super(props); 
        this.state={radio:''}
    }

    updateRadioButton(e) {
        this.setState({ radio: e.target.value });
    }

    <RadioGroup horizontal>
            <RadioButton value="Male">Male</RadioButton>
            <RadioButton value="Female">Female</RadioButton>
        </RadioGroup>

好吧，根据DOCS在此库中，RadioGroup 有一个 onChange 属性处理程序，您可以传递该处理程序，该处理程序将返回选定的值，然后您可以将其设置在状态中或将其传递。

这是您的代码的小型运行示例:

debugger
const RadioGroup = ReactRadioButtonsGroup.ReactRadioButtonsGroup;
const RadioButton = ReactRadioButtonsGroup.ReactRadioButton;

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {};
  }

  onRadiochange = value => {
    console.log(value);
  };

  render() {
    return (
      <div>
        <RadioGroup horizontal onChange={this.onRadiochange}>
          <RadioButton value="Male">Male</RadioButton>
          <RadioButton value="Female">Female</RadioButton>
        </RadioGroup>
      </div>
    );
  }
}

ReactDOM.render(<App />, document.getElementById("root"));
