Question

dev->cdev.ops = &scull_fops

当我打开index.html并且chrome的调试告诉我时，我没有查看任何内容：＆＃34; 未公开的正则表达式＆＃34;

您应该使用react-dom代替。

ReactDOM.render(<Lamp color="green" />, document.body)

class Lamp extends React.Component {
  constructor() {
    super()

    this.state = {
      active: false,
    }

    this.toggleActive = this.toggleActive.bind(this)
  }

  toggleActive() {
     this.setState({ active: !this.state.active })
  }

  render() {
    return (
      <div
        style={{ backgroundColor: this.state.active ? 'green' : 'red' }}
      >
        lampada
        <button onClick={this.toggleActive}>on/off</button>
       </div>
    )
  }
}

ReactDOM.render(
  <Lamp />,
  document.getElementById('root')
)
