React组件内事件传参实现tab切换的示例代码

import 'babel-polyfill';
import React from 'react';
import ReactDOM from 'react-dom';
import './index.scss'

class TabButton extends React.Component {

    constructor(props) {
      super(props);
      this.state = {
        markArray: [0, 0, 0, 0], 
        itemClassName:'tab-button-item'
      };
      this.activateButton = this.activateButton.bind(this);
    }

    // 根据参数id, 来确定激活四个item中的哪一个
    activateButton(id) {
      let tmpMarkArray = [0, 0, 0, 0]
      tmpMarkArray[id] = 1;
      this.setState({markArray: tmpMarkArray});
    }

    render() {
      return ( 

        


        
 零 
 
        
 壹 
 
        
 贰 
 
        
 叁 

        
)
      }

    }

    ReactDOM.render(  , document.getElementById("root"));
