[英]How can style the backdrop of a MaterialUI modal?
我設置了一個 MUI 模式,它目前正在運行,但背景顯示為黑色。 我有適當的樣式,但由於某種原因,背景沒有更新並且仍然是黑色。
我的代碼在下面,屏幕截圖也在打開模式時看到的屏幕截圖。 請讓我知道如何解決此問題。
import { Box, Modal, Typography } from "@material-ui/core";
import React from "react";
import { makeStyles } from "@material-ui/core/styles";
const useStyles = makeStyles((theme) => ({
modalStyle: {
position: "absolute",
top: "50%",
left: "50%",
transform: "translate(-50%, -50%)",
width: 300,
bgcolor: "background.paper",
boxShadow: 24,
p: 4,
backgroundColor: "white",
borderRadius: "10px",
},
}));
const PopupModal = ({ postModalOpen, handleClose, children }) => {
const classes = useStyles();
return (
<Modal open={postModalOpen} onClose={handleClose}>
<Box className={classes.modalStyle}>
ModalText
<Typography
id="modal-modal-title"
variant="h6"
component="h2"
style={{
fontSize: "14px",
marginLeft: "5px",
}}
>
{children}
</Typography>
</Box>
</Modal>
);
};
export default PopupModal;
如果您想為背景設置樣式,您的 styles 必須直接傳遞給Modal
組件:
例如:
const useStyles = makeStyles((theme) => ({
/** Changed modalStyle */
modalStyle: { backgroundColor: "rgba(255, 0, 0, 0.5)" },
/** Moved content styling to new class */
contentStyle: {
/** Also removed some invalid attributes **/
position: "absolute",
top: "50%",
left: "50%",
transform: "translate(-50%, -50%)",
width: "300px",
backgroundColor: "white",
borderRadius: "10px"
}
}));
const PopupModal = ({ postModalOpen, handleClose, children }) => {
const classes = useStyles();
return (
// Note the changed className props with your sample code
<Modal
open={postModalOpen}
onClose={handleClose}
className={classes.modalStyle}
>
<Box className={classes.contentStyle}>
<Typography
id="modal-modal-title"
variant="h6"
component="h2"
style={{
fontSize: "14px",
marginLeft: "5px"
}}
>
{children}
</Typography>
</Box>
</Modal>
);
};

這就是我自定義 MUI 背景的方式 (MUI v5)
<Backdrop open={isOpen} sx={{ backgroundColor: 'rgba(0, 0, 0, 0.25)', zIndex: 1 }} onClick={handleCloseMenu} />
