|

## 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.
|
|
|
|
````jsx
|
|
import { Slider, Icon } from 'antd';
|
|
|
|
class IconSlider extends React.Component {
|
|
state = {
|
|
value: 0,
|
|
}
|
|
handleChange = (value) => {
|
|
this.setState({ value });
|
|
}
|
|
render() {
|
|
const { max, min } = this.props;
|
|
const { value } = this.state;
|
|
const mid = ((max - min) / 2).toFixed(5);
|
|
const preColor = value >= mid ? '' : 'rgba(0, 0, 0, .45)';
|
|
const nextColor = value >= mid ? 'rgba(0, 0, 0, .45)' : '';
|
|
return (
|
|
<div className="icon-wrapper">
|
|
<Icon style={{ color: preColor }} type="frown-o" />
|
|
<Slider {...this.props} onChange={this.handleChange} value={value} />
|
|
<Icon style={{ color: nextColor }} type="smile-o" />
|
|
</div>

);
