在React.js中重置RadioGroup值

import React, { Component } from 'react';

class RadioGroup extends Component {
  constructor(props) {
    super(props);
    this.state = {
      selectedValue: null
    };
  }

  handleRadioChange = (event) => {
    this.setState({
      selectedValue: event.target.value
    });
  }

  render() {
    const { data } = this.props;
    const { selectedValue } = this.state;

    return (
      <div>
        {data.map((item) => (
          <label key={item.value}>
            <input
              type="radio"
              value={item.value}
              checked={selectedValue === item.value}
              onChange={this.handleRadioChange}
            />
            {item.label}
          </label>
        ))}
      </div>
    );
  }
}

export default RadioGroup;

import React, { Component } from 'react';
import RadioGroup from './RadioGroup';

class App extends Component {
  resetRadioGroup = () => {
    this.radioGroupRef.setState({
      selectedValue: null
    });
  }

  render() {
    const radioData = [
      { value: 'option1', label: 'Option 1' },
      { value: 'option2', label: 'Option 2' },
      { value: 'option3', label: 'Option 3' }
    ];

    return (
      <div>
        <RadioGroup ref={(ref) => this.radioGroupRef = ref} data={radioData} />
        <button onClick={this.resetRadioGroup}>Reset</button>
      </div>
    );
  }
}

export default App;
