[英]Material-UI: classes isn't working with external SVG icons?
我創建了一個 Material-UI 持久抽屜,其中有一個列表項組件,旨在在用戶單擊列表項時更改圖標顏色。 但我的樣式僅適用於 Material-UI 圖標,不適用於外部 SVG。
這是同一項目的代碼框鏈接,可以更好地理解它。
這是呈現我的 listItem 組件的AppBarDrawer.js
父組件。 工作正常,可以忽略

沒有給出期望的主文件DrawerList.js
這里真正的問題是,每當我點擊它時,我的外部圖標顏色都不會變為白色,但是最后一個名為ExitToAppOutlined
的圖標是 Material-UI 圖標,點擊時效果很好。
import React, { useState } from "react";
import ListItem from "@material-ui/core/ListItem";
import Link from "@material-ui/core/Link";
import ListItemIcon from "@material-ui/core/ListItemIcon";
import { ExitToAppOutlined } from "@material-ui/icons";
import ListItemText from "@material-ui/core/ListItemText";
import { useStyles } from "./DrawerListStyle";
import Typography from "@material-ui/core/Typography";
import Box from "@material-ui/core/Box";
import { SvgIcon } from "@material-ui/core";
import { ReactComponent as Appointment } from "../../assets/Appointment.svg";
import { ReactComponent as Customers } from "../../assets/manage customers 2.svg";
const itemList = [
{
text: "Book Appointment",
icon: (
<SvgIcon>
{/* external icons as svg */}
<Appointment />
</SvgIcon>
)
},
{
text: "Manage",
icon: (
<SvgIcon>
{/* external icons as svg */}
<Customers />
</SvgIcon>
)
},
{
text: "Logout",
// Material Icons
icon: <ExitToAppOutlined />
}
];
const DrawerList = () => {
const [selectedIndex, setSelectedIndex] = useState(0);
const classes = useStyles();
const ListData = () =>
itemList.map((item, index) => {
const { text, icon } = item;
return (
<ListItem
button
key={text}
component={Link}
selected={index === selectedIndex}
onClick={(e) => handleListItemClick(e, index)}
style={selectedIndex === index ? { backgroundColor: "#6A2CD8" } : {}}
>
<ListItemIcon
className={classes.iconStyle}
style={selectedIndex === index ? { color: "#fff" } : {}}
>
{icon}
<ListItemText>
<Typography
component="div"
className={classes.iconTitle}
style={selectedIndex === index ? { color: "#fff" } : {}}
>
<Box fontWeight={500} fontSize={13.5}>
{text}
</Box>
</Typography>
</ListItemText>
</ListItemIcon>
</ListItem>
);
});
const handleListItemClick = (e, index) => {
setSelectedIndex(index);
};
return (
<div className={classes.root}>
<ListData />
</div>
);
};
export default DrawerList;
DrawerListStyle.js
只是一個 stylejs 文件,可以忽略
import { makeStyles } from "@material-ui/core";
const useStyles = makeStyles((theme) => ({
root: {
marginTop: theme.spacing(2)
},
iconStyle: {
margin: theme.spacing(0, 0, 1, 0),
color: "#6A2CD8"
},
iconTitle: {
margin: theme.spacing(0, 0, 0, 1),
color: "#555458"
}
}));
export { useStyles };
Material-UI 在選擇ListItemIcon
時設置ListItem
的color
,但是因為您的自定義svg
圖標已經將fill
屬性設置為另一種顏色,它會覆蓋 MUI 中的color
。 修復很簡單,使用makeStyles
在您的自定義 svg 中再次覆蓋fill
屬性:
const useStyles = makeStyles((theme) => ({
{...}
listItem: {
"&.Mui-selected": {
"& path": {
fill: "white"
}
}
}
}));
<ListItem className={classes.listItem}
您還可以使用SVGR
構建自己的圖標。
您可以按照以下步驟操作:
1-使用安裝 svgr
npm install --save-dev @svgr/cli
# or use yarn
yarn add --dev @svgr/cli
2-在public/icons
3-創建一個名為svgr.config.js
的文件並將其放在項目的根目錄中
module.exports = {
icon: true,
dimensions: false,
expandProps: false,
replaceAttrValues: {
'#000': 'currentColor',
'#292D32': 'currentColor',
'#292d32': 'currentColor',
'#55BB9D': 'currentColor',
'#FFBC50': 'currentColor',
'#A7A7A7': 'currentColor'
}
};
4- 在 package.json "svg": "svgr --ext=jsx -d src/@share/icons public/icons"
中添加腳本
5 運行yarn svg
。
一旦你運行上面的命令 svgr 抓取公共文件夾中的所有圖標,並根據你提供的配置在src/@share/icons
文件夾中生成 React 組件。 並將 svg 的每個顏色文本替換為當前顏色。 在這種情況下,將replaceAttrValues
中的每個鍵替換為currentColor
。
然后在您的反應組件中,您可以簡單地執行以下操作:
import { MyIcon } from '@share/icons';
import { SvgIcon } from '@mui/material';
function MyComponent() {
return <p><SvgIcon component={MyIcon} /> check this icon </p>
};
export default MyComponent;
這樣,您可以像更改p
元素的文本顏色一樣更改顏色。
