React 快速检测用户是否离开

2026/03/05

在主 class 中直接调用函数，函数实现细节如下

const useLeave = (event: Event) => {
    const customEvent = event as CustomEvent;
    if (customEvent.detail.url != ' path that you need to put here '){
        // do the action that you want
    }

    useEffect(()=&gt;{
        document.addEventListener('oxg-header--navigate',leave);
        return ()=&gt;document.removeEventListenser('oxg-header--navigate',leave);
    },[]);

    return null;
}

export default useLeave;
