1.多个选项卡如何实现？
2.平级的 通过操作number 所有的都开始联动了!
3.我的需求是 只向那一个选项卡 那一个选项卡开始切换

export default class Floor extends React.Component {
  constructor() {
    super();
    this.state = {
      floor: [],
      current:0,
      number:0
    };
  }

  onMouseEnter(e) {

    this.setState({
      current: e.target.getAttribute("data-index")
    })
  }

<div className="keywords">
