我做了一个材料 ui popper 我添加了一个按钮 (x( 来关闭波普尔。
我添加了一个按钮和一个 const 句柄关闭，应该在单击时关闭波普尔，但这不起作用(什么也没发生(每个波普尔都有自己的类
这是我的经历，我的波普尔是在创建的地方
const Experiences = memo(
(props) => {
const { className } = props;
const classes = useStyles(props);
const [anchorEl, setAnchorEl] = React.useState(null);
const handleClick = (event) => {
setAnchorEl(event.currentTarget);
};
// const open = Boolean(anchorEl);
const handleClose = () => {
setAnchorEl({
open: false
});
};
const experience = (img, title, id, popoverCategory) => (
<div
className="experience"
aria-describedby={id}
id={id}
onClick={handleClick}
onKeyDown={handleClick}
role="button"
tabIndex="0"
>
<img
data-sizes="auto"
className="lazyload"
data-src={img}

<div className="experience-title">

<Popper
