如何在 ReactJS 中将具有属性的 CSS 转换为 MaterialUI 样式
How to convert CSS with properties to MaterialUI Styles in ReactJS
我有以下 CSS:
[contentEditable=true]:empty:not(:focus):before{
content:attr(data-text)
}
允许在内容可编辑 div 没有内容时显示占位符。我正在使用 Material-UI 样式,所以我需要这样的东西:
const styles = theme => ({
div[contentEditable=true]:empty:not(:focus):before: {
content:attr(data-text)
}
});
我怎样才能做到这一点?有什么想法吗?
谢谢。
下面是一些语法选项,具体取决于您是想直接在 div (editableDiv
) 上还是在祖先元素 (container
上指定 class ).两者之间的唯一区别是当定位后代时 &
之后的 space。
import React from "react";
import ReactDOM from "react-dom";
import { makeStyles } from "@material-ui/core/styles";
const useStyles = makeStyles({
container: {
"& [contentEditable=true]:empty:not(:focus):before": {
content: "attr(data-text)"
}
},
editableDiv: {
"&[contentEditable=true]:empty:not(:focus):before": {
content: "attr(data-text)"
}
}
});
function App() {
const classes = useStyles();
return (
<div>
<div className={classes.container}>
<div contentEditable data-text="Click here to edit div 1" />
<div contentEditable data-text="Click here to edit div 2" />
</div>
<div
className={classes.editableDiv}
contentEditable
data-text="Click here to edit div 3"
/>
</div>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
