## zh-CN
|
|
|
|
滑块左右可以设置图标来表达业务含义。
|
|
|
|
## en-US
|
|
|
|
You can add an icon beside the slider to make it meaningful.
|
|
|
|
```tsx
|
|
import { FrownOutlined, SmileOutlined } from '@ant-design/icons';
|
|
import { Slider } from 'antd';
|
|
import React, { useState } from 'react';
|
|
|
|
interface IconSliderProps {
|
|
max: number;
|
|
min: number;
|
|
}
|
|
|
|
const IconSlider: React.FC<IconSliderProps> = props => {
|
|
const { max, min } = props;
|
|
const [value, setValue] = useState(0);
|
|
|
|
const mid = Number(((max - min) / 2).toFixed(5));
|
|
const preColorCls = value >= mid ? '' : 'icon-wrapper-active';
|
|
const nextColorCls = value >= mid ? 'icon-wrapper-active' : '';
|
|
|
|
return (
|
|
<div className="icon-wrapper">
|
|
<FrownOutlined className={preColorCls} />
|
|
<Slider {...props} onChange={setValue} value={value} />
|
|
<SmileOutlined className={nextColorCls} />
|
|
</div>
|
|
);
|
|
};
|
|
|
|
const App: React.FC = () => <IconSlider min={0} max={20} />;
|
|
|
|
export default App;
|
|
```
|
|
|
|
```css
|
|
.icon-wrapper {
|
|
position: relative;
|
|
padding: 0px 30px;
|
|
}
|
|
|

.icon-wrapper .anticon {
|
|
position: absolute;
|
|
top: -2px;
|
|
width: 16px;
|
|
height: 16px;
|
|
color: rgba(0, 0, 0, 0.25);

font-size: 16px;

line-height: 1;

.icon-wrapper .icon-wrapper-active {

}
|
|
|

.icon-wrapper .anticon:last-child {
|
|
right: 0;
|
|
}
|
|
```
|
|
|
|
<style>
|
|
[data-theme="dark"] .icon-wrapper .anticon {
|
|
color: rgba(255, 255, 255, 0.25);
|
|
}
|
|
[data-theme="dark"] .icon-wrapper .icon-wrapper-active {
|
|
color: rgba(255, 255, 255, .45);
