React Hooks下使用antd Modal监听键盘事件，图片预览组件

因为项目中使用了antd.业务上有个需求，需要预览图片。想到了antd里面有个modal.稍作修改就只需要处理前后翻页的业务逻辑就行。
1，可以通过前一张，后一张按钮来进行翻页，图片右上角有退出预览按钮
2，键盘的左右按钮可以前后翻页，ESC按钮可以退出预览

代码如下：

interface IpicPreviewProps{
    index:number; // 第几张图片索引值
    pic:any[];  // 图片链接数组，存储图片地址
    modalShow:boolean; // modal显示和隐藏
    setModalShow:(v:boolean) => void; // 回调
}

function PicturePreview(props:IpicPreviewProps) :JSX.Element {
    const {modalShow,index,pic} = props;
    const [current,setCurrent] = useState('');  // 用于存放当前显示图片地址
    const [currentIndex,setCurrentIndex] = useState(0); // 用于存放当前播放图片在数组中索引值
    
    useEffect(()=>{
        document.addEventListener('keyup',upHandle);
        retrurn ()=>{
            document.removeEventListener('keyup',upHandle);
        }
    },[currentIndex]);
    
    useEffect(()=>{
        setCurrent(pic[index]);
        setCurrentIndex(index);
    },[idnex,pic]);
    
    const leftClick = useMemo(()=>
        ()=>{
            if(currentIndex !== 0){
                setCurrentIndex((prev:number) => prev-1);
                sestCurrent(pic[currentIndex-1]);
            }
        },[currentIndex,pic]);
    
    const rightClick = useMemo(()=>
        () =>{
            const length = pic.length;
            if(currentIndex !== length -1){
                setCurrentIndex((prev:number) =>prev +1);
                setCurrent(pic[currentIndex +1]);
            }
        },[currentIndex,pic]);
        
     const upHandle = useMemo(()=>
        (e:any) =>{
            if(e.keyCode === 37){ // left
                leftClick();
            } else if(e.keyCode === 39){ // right
                rightClick();
            } else if(e.keyCode === 27){ // esc
                props.setModalShow(false);
            }
        },[leftClick,rightClick,props.setModalShow]);
      
      return (
        
            

                

                

                    
                    {props.setModalShow(false)}}/>
                 
                 

             
          
      )
        
}

export default Memo(PicturePreview);
