react 如何銷毀組件并觸發(fā)離場事件？比如以下代碼。javascript :const ComBox = () => {    const HideAni = () =>{        //這里如何觸發(fā)銷毀？？？？     }    return (        <div>             <div onClick={()=> HideAni()}>銷毀按鈕</div>             <ReactCSSTransitionGroup                  transitionName="example"                 transitionLeaveTimeout={300}             >                 <p>我是要銷毀的內(nèi)容</p>             </ReactCSSTransitionGroup>             {box}        </div>     ) }CSS :.example-leave {    opacity: 1; }.example-leave.example-leave-active {    opacity: 0.01;    transition: opacity 300ms ease-in; }當(dāng)我點(diǎn)擊 銷毀按鈕 的時(shí)候，如何才能銷毀下面的內(nèi)容，并觸發(fā)離場動(dòng)畫？
