React子组件怎么改变父组件的state

 

1.父组件

class Father extends React.Component {

    construtor(props){
        super(props);
        this.state={
            isRed: 0
        }
    }
    onChangeState(isTrue){
        this.setState(isTrue)
    }
    render(){
        <p>颜色：{this.state.isRed}</p>
        <Child onClicked={this.onChangeState.bind(this)}/>
    }
}

　　

2.子组件

class Child extends React.Component {
    render(){
        <Button onClicked={()=>this.props.onClicked({isRed: 1})}/>
    }
}
