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(){        
颜色：{this.state.isRed}
        
     
          }}
     

　　

2.子组件

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