React将属性传递给其他组件以从状态数组中删除

class ParentComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      data: ['item1', 'item2', 'item3']
    };
  }

  render() {
    return <ChildComponent data={this.state.data} />;
  }
}

class ChildComponent extends React.Component {
  render() {
    const { data } = this.props;

    return (
      <div>
        {data.map(item => (
          <div key={item}>{item}</div>
        ))}
      </div>
    );
  }
}

class ParentComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      data: ['item1', 'item2', 'item3']
    };
  }

  handleDelete = item => {
    const newData = this.state.data.filter(i => i !== item);
    this.setState({ data: newData });
  };

  render() {
    return <ChildComponent data={this.state.data} onDelete={this.handleDelete} />;
  }
}

class ChildComponent extends React.Component {
  render() {
    const { data, onDelete } = this.props;

    return (
      <div>
        {data.map(item => (
          <div key={item}>
            {item}
            <button onClick={() => onDelete(item)}>删除</button>
          </div>
        ))}
      </div>
    );
  }
}
