Material UI 的 Toggle Button 组件是一种非常直观和用户友好的控件,允许用户在两种状态之间进行切换。它常用于开关功能、选项选择等场景。本文将详细介绍 Toggle Button 的使用,包括基本用法、所有属性和方法的详细解释,以及与其他组件的结合示例。
确保您已经安装了 Material UI。如果还没有,可以通过以下命令进行安装:
npm install @mui/material @emotion/react @emotion/styled
下面是一个简单的 Toggle Button 示例,展示了如何使用该组件。
import React, { useState } from 'react';
import { ToggleButton, ToggleButtonGroup } from '@mui/material';
const ToggleButtonExample = () => {
const [alignment, setAlignment] = useState('left');
const handleAlignment = (event, newAlignment) => {
if (newAlignment !== null) {
setAlignment(newAlignment);
}
};
return (
<ToggleButtonGroup
value={alignment}
exclusive
onChange={handleAlignment}
aria-label="text alignment"
>
<ToggleButton value="left" aria-label="left aligned">
左对齐
</ToggleButton>
<ToggleButton value="center" aria-label="center aligned">
居中
</ToggleButton>
<ToggleButton value="right" aria-label="right aligned">
右对齐
</ToggleButton>
</ToggleButtonGroup>
);
};
export default ToggleButtonExample;
将 Toggle Button 与 Checkbox 结合,允许用户选择多个选项。
import React, { useState } from 'react';
import {
ToggleButton,
ToggleButtonGroup,
Checkbox,
Typography,
Box,
} from '@mui/material';
const ToggleButtonWithCheckbox = () => {
const [alignment, setAlignment] = useState('left');
const [checkedItems, setCheckedItems] = useState([true, false, false]);
const handleAlignment = (event, newAlignment) => {
if (newAlignment !== null) {
setAlignment(newAlignment);
}
};
const handleCheckboxChange = (index) => {
const updatedItems = [...checkedItems];
updatedItems[index] = !updatedItems[index];
setCheckedItems(updatedItems);
};
return (
<Box>
<Typography variant="h6">选择对齐方式</Typography>
<ToggleButtonGroup
value={alignment}
exclusive
onChange={handleAlignment}
aria-label="text alignment"
>
<ToggleButton value="left" aria-label="left aligned">
左对齐
</ToggleButton>
<ToggleButton value="center" aria-label="center aligned">
居中
</ToggleButton>
<ToggleButton value="right" aria-label="right aligned">
右对齐
</ToggleButton>
</ToggleButtonGroup>
<Box mt={2}>
<Typography variant="h6">选择项目</Typography>
{['项目 A', '项目 B', '项目 C'].map((item, index) => (
<Box key={item}>
<Checkbox
checked={checkedItems[index]}
onChange={() => handleCheckboxChange(index)}
/>
{item}
</Box>
))}
</Box>
</Box>
);
};
export default ToggleButtonWithCheckbox;
将 Toggle Button 嵌入到 Form 中,允许用户提交选项。
import React, { useState } from 'react';
import {
Box,
Button,
TextField,
ToggleButton,
ToggleButtonGroup,
Typography,
} from '@mui/material';
const ToggleButtonForm = () => {
const [alignment, setAlignment] = useState('left');
const [name, setName] = useState('');
const handleAlignment = (event, newAlignment) => {
if (newAlignment !== null) {
setAlignment(newAlignment);
}
};
const handleSubmit = (event) => {
event.preventDefault();
alert(`选择的对齐方式: ${alignment},姓名: ${name}`);
};
return (
<form onSubmit={handleSubmit}>
<Typography variant="h6">选择对齐方式</Typography>
<ToggleButtonGroup
value={alignment}
exclusive
onChange={handleAlignment}
aria-label="text alignment"
>
<ToggleButton value="left" aria-label="left aligned">
左对齐
</ToggleButton>
<ToggleButton value="center" aria-label="center aligned">
居中
</ToggleButton>
<ToggleButton value="right" aria-label="right aligned">
右对齐
</ToggleButton>
</ToggleButtonGroup>
<Box mt={2}>
<TextField
label="姓名"
variant="outlined"
value={name}
onChange={(e) => setName(e.target.value)}
/>
</Box>
<Button variant="contained" color="primary" type="submit" sx={{ mt: 2 }}>
提交
</Button>
</form>
);
};
export default ToggleButtonForm;
您可以通过使用 sx
属性或者自定义 CSS 类来修改 Toggle Button 的样式。例如:
<ToggleButton
value="left"
aria-label="left aligned"
sx={{ borderRadius: '20px', bgcolor: alignment === 'left' ? 'primary.main' : 'grey.200' }}
>
左对齐
</ToggleButton>
当用户选择 Toggle Button 后,显示 Snackbar 提示。
import React, { useState } from 'react';
import {
ToggleButton,
ToggleButtonGroup,
Snackbar,
Button,
Typography,
Box,
} from '@mui/material';
const ToggleButtonWithSnackbar = () => {
const [alignment, setAlignment] = useState('left');
const [open, setOpen] = useState(false);
const handleAlignment = (event, newAlignment) => {
if (newAlignment !== null) {
setAlignment(newAlignment);
setOpen(true);
}
};
const handleClose = () => {
setOpen(false);
};
return (
<Box>
<Typography variant="h6">选择对齐方式</Typography>
<ToggleButtonGroup
value={alignment}
exclusive
onChange={handleAlignment}
aria-label="text alignment"
>
<ToggleButton value="left" aria-label="left aligned">
左对齐
</ToggleButton>
<ToggleButton value="center" aria-label="center aligned">
居中
</ToggleButton>
<ToggleButton value="right" aria-label="right aligned">
右对齐
</ToggleButton>
</ToggleButtonGroup>
<Snackbar
open={open}
autoHideDuration={3000}
onClose={handleClose}
message={`您选择了 ${alignment} 对齐方式`}
action={
<Button color="inherit" onClick={handleClose}>
关闭
</Button>
}
/>
</Box>
);
};
export default ToggleButtonWithSnackbar;
