zh-CN

当 Slider 的值发生改变时，会触发 onChange 事件，并把改变后的值作为参数传入。在 onmouseup 时，会触发 onAfterChange 事件，并把当前值作为参数传入。

en-US

The onChange callback function will fire when the user changes the slider's value. The onAfterChange callback function will fire when onmouseup fired.

import { Slider } from 'antd';

function log(value) {
  console.log(value);
}

ReactDOM.render(
  <div>
    <Slider defaultValue={30} onChange={log} />
    <Slider range step={10} defaultValue={[20, 50]} onChange={log} />
    <Slider defaultValue={30} onAfterChange={log} />
  </div>
, mountNode);
