Disabled:

Basic slider. When range is true, display as dual thumb mode. When disable is true, the slider will not be interactable.

import { Slider, Switch } from 'antd';

class Demo extends React.Component {
  state = {
    disabled: false,
  };

  handleDisabledChange = (disabled) => {
    this.setState({ disabled });
  }

  render() {
    const { disabled } = this.state;
    return (
      <div>
        <Slider defaultValue={30} disabled={disabled} />
        <Slider range defaultValue={[20, 50]} disabled={disabled} />
        Disabled: <Switch size="small" checked={disabled} onChange={this.handleDisabledChange} />
      </div>
    );
  }
}

ReactDOM.render(<Demo />, mountNode);

You can add an icon beside the slider to make it meaningful.

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>
    );
  }
}

ReactDOM.render(<IconSlider min={0} max={20} />, mountNode);
.icon-wrapper {
  position: relative;
  padding: 0px 30px;
}

.icon-wrapper .anticon {
  position: absolute;
  top: -2px;
  width: 16px;
  height: 16px;
  line-height: 1;
  font-size: 16px;
  color: rgba(0, 0, 0, .25);
}

.icon-wrapper .anticon:first-child {
  left: 0;
}

.icon-wrapper .anticon:last-child {
  right: 0;
}

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 onChange(value) {
  console.log('onChange: ', value);
}

function onAfterChange(value) {

  <div>
    <Slider defaultValue={30} onChange={onChange} onAfterChange={onAfterChange} />
    <Slider range step={10} defaultValue={[20, 50]} onChange={onChange} onAfterChange={onAfterChange} />

Synchronize with InputNumber component.

class IntegerStep extends React.Component {
  state = {
    inputValue: 1,
  }

  onChange = (value) => {

Use tipFormatter to format content of Toolip. If tipFormatter is null, hide it.

import { Slider } from 'antd';

function formatter(value) {
  return `${value}%`;
}

ReactDOM.render(
  <div>
    <Slider tipFormatter={formatter} />
    <Slider tipFormatter={null} />
  </div>,
  mountNode

Using marks property to mark a graduated slider, use value or defaultValue to specify the position of thumb. When included is false, means that different thumbs are coordinative. when step is null, users can only slide the thumbs onto marks.

import { Slider } from 'antd';

const marks = {
  0: '0°C',
  26: '26°C',
  37: '37°C',
  100: {
    style: {
      color: '#f50',
    },
    label: <strong>100°C</strong>,
  },
};

ReactDOM.render(
  <div>
    <h4>included=true</h4>
    <Slider marks={marks} defaultValue={37} />
    <Slider range marks={marks} defaultValue={[26, 37]} />

    <h4>included=false</h4>
    <Slider marks={marks} included={false} defaultValue={37} />

    <h4>marks & step</h4>
    <Slider marks={marks} step={10} defaultValue={37} />

    <h4>step=null</h4>
