reactjs 怎样实现多个按钮中，每次点击其中任意一个按钮，只会改变其背景色？

各位大神好：

    我想用reactjs实现一个效果，在多个按钮中，每次点击其中任意一个按钮，只会改变其背景色。（效果图已上传，请参考

class Quesitons2 extends React.Component{
    state = {
        currentQuestion: {},
        active: false
    }

    selectQuesion = (question) => {
        this.setState({
            currentQuestion: question,
            active: true
        })
    }

    render(){
        const _class = {
            true: 'question active',
            false: 'question'
        }

        return(
            <div className="questions">
                <div className="columns is-multiline is-desktop ">
                    <div className="panel-container">
                        <Panel currentQuestion={this.state.currentQuestion}/>
                    </div>

                    {questions.map( q => {
                        return(
                            <button
                                className = {_class[this.state.active]}

                                key={q.id}
                                onClick={() => this.selectQuesion(q)}
                            >
                                {q.name}
                            </button>
                        )
                    })}
                </div>
            </div>
        )
    }
}

重新上传效果图

class Quesitons2 extends React.Component{
    state = {
        currentQuestion: {},
        active: false
    }
 
    selectQuesion = (e, question) => {
              e.stopPropagation();
              e.target.style.background = 'red';
        this.setState({
            currentQuestion: question,
            active: true
        })
    }
 
    render(){
        const _class = {
            true: 'question active',
            false: 'question'
        }
 
        return(
            <div className="questions">
                <div className="columns is-multiline is-desktop ">
                    <div className="panel-container">
                        <Panel currentQuestion={this.state.currentQuestion}/>
                    </div>
 
                    {questions.map( q => {
                        return(
                            <button
                                key={q.id}
                                onClick={e => this.selectQuesion(e, q)}
                            >
                                {q.name}
                            </button>
                        )
                    })}
                </div>
            </div>
        )
    }
}

e.stopPropagation(); // 阻止点击事件的冒泡
e.target.style.background = 'red'; // 改变背景色
