import { Slider, Icon } from 'antd';

const IconSlider = React.createClass({
  getInitialState() {
    const max = this.props.max;
    const min = this.props.min;
    const mid = ((max - min) / 2).toFixed(5);

    return {
      preIconClass: this.props.value >= mid ? '' : 'anticon-highlight',
      nextIconClass: this.props.value >= mid ? 'anticon-highlight' : '',
      mid,
      sliderValue: this.props.value
    };
  },

  handleChange(v) {
    this.setState({
      preIconClass: v >= this.state.mid ? '' : 'anticon-highlight',
      nextIconClass: v >= this.state.mid ? 'anticon-highlight' : '',
      sliderValue: v
    });
  },

  render() {
    return (
      <div className="iconWrapper">
        <Icon className={this.state.preIconClass} type={this.props.icon[0]} />
        <Icon className={this.state.nextIconClass} type={this.props.icon[1]} />
        <Slider {...this.props} onChange={this.handleChange} value={this.state.sliderValue} />
      </div>
    );
