setState bug

[showzyl]

componentDidMount 里 setState render 不执行。

class Page109 extends Component {
  constructor(props) {
    super(props);
    this.state = {
      show: false
    }
  }

  componentDidMount() {
    this.setState({
      show: true
    }, () => {
      console.log(`componentDidMount here: `)
      console.log(`this.state: `, this.state)
    })
  }
  
  render() {
    let img = utils.isSupportWebp() ? require('./assets/1.webp') : require('./assets/1.jpg')
    console.log(`render state: `, this.state)
    return (
      <div className="page109">
        <img className="imgs" src={img} alt=""/>
        <div className="box">
          <img src={require('./assets/2.jpg')}/>
          {this.state.show ? <ul className="">
            我是内容
          </ul> : ""}
        </div>
      </div>
    )
  }
}

export default Page109
