react高階組件包裹的組件如何操作高階組件內(nèi)的state?

向子組件傳遞方法，然后在子組件里面調(diào)用該方法。

const fn=(Com)=>{
    return class A extends Component{
        state={
            list
        }
        handleList = () => {
           // to do ...
           this.setState({
             list: ...
           })
        }
        return <Com handleList={this.handleList} {...this.props}/>
    }
}

class Com extends Components {
    state = {}
    handleList = () => this.props.handleList()
    
    return (
        ....
    )
}

普通組件怎么操作，高階組件就怎么操作

const fn=(Com)=>{
    return class A extends Comonents{
        state={
            list
        }
        componentDidMount(){
            fetch('/XXX')
            .then(res=>{
                ...
                this.setState({...});
            })
        }
        render(){
            return <Com  {...this.props}/>
        }
    }
}

const NewCom = fn(Com);

生命周期?props?

const fn=(Com)=>{
    return class A extends Comonents{
        state={
            list
        }
        return <Com list={this.state.list} {...this.props}/>
    }
}
