我的方法不同,每个工具提示都保持自己的状态。它使用IntersectionObserver 来确定@987654325@ 组件是否可见。当组件不再可见时,它将隐藏Popper(工具提示弹出窗口),方法是通过PopperProps 上的sx 属性将CSS 设置为display: 'none'。
代码沙盒示例:Here
这是修改后的文件FileDownloadButton.jsx:
import React from "react";
import FileDownloadIcon from "@mui/icons-material/FileDownload";
import { ButtonGroup, Tooltip } from "@mui/material";
export default function FileDownloadButton() {
const tipRef = React.useRef(null);
const [inView, setInView] = React.useState(false);
const cb = (entries) => {
const [entry] = entries;
entry.isIntersecting ? setInView(true) : setInView(false);
};
React.useEffect(() => {
const options = {
root: null,
rootMargin: "0px"
};
const ref = tipRef.current;
const observer = new IntersectionObserver(cb, options);
if (ref) observer.observe(ref);
return () => {
if (ref) observer.unobserve(ref);
};
}, [tipRef]);
return (
<ButtonGroup>
<div>
<Tooltip
ref={tipRef}
title="Download record "
arrow
componentsProps={{
tooltip: {
sx: {
bgcolor: "#a3a3a3",
"& .MuiTooltip-arrow": {
color: "#a3a3a3"
}
}
}
}}
PopperProps={{
sx: { display: inView ? "block" : "none" },
modifiers: [
{
name: "offset",
options: {
offset: [0, -8]
}
}
]
}}
>
<FileDownloadIcon />
</Tooltip>
</div>
</ButtonGroup>
);
}
