如何访问子女组件中的父组件方法，例如以下示例

Question

//this is the parent component in ibios.js file
import  React from 'react';
import ReactDOM from 'react-dom';
import axios from 'axios';
class ibios extends React.Component{
  constructor(){
        super();
        this.sate={};
        this.get = this.get.bind(this);
    }
 get(ur,apiurl,prametars){
  prametars=prepareHeaderRequest;
    return axios.get(url+apiUrl,{params:prametars})
            .then(function(response){
                console.log(response.data);
            });
    }
    render(){
        return(
            <p>hi...</p>
            );
   }
}
//this is the child component chart component.js file
import React from 'react';
import ibios from '../ibios/IBIOS';
import ChartComponent from './chartcomponents';
class BarChartComponent extends ChartComponent{
  constructor(props){
        super(props)
        this.state={};  
    }
   componentDidMount(){
      //example
       var url="http://localhost:9090",apiUrl="/reports",prametrs={xyz:ramki};
     var retriveResponse=this.ibios.get(url,apiUrl,prametrs)
     console.log(retriveResponse);
   }
  render(){
     return(<p>hi......</p>);
  }
}

Answer 1

class First extends React.Component {
  first() {
    alert("First")
  }
  render() {
    return <div>sdfsdf</div>
  }
}
class Second extends First {
  second() {
    alert('Second')
  }
  render() {
    return <div>dsfsdfsdf</div>
  }
}
class Third extends Second {
  onButtonClick() {
    super.second()
    super.first()
  }
  render() {
    return <button onClick={() =>     {this.onButtonClick()}}>Hello</button>;
  }
}
ReactDOM.render(
  <Third />,
  document.getElementById('container')
);

You should extend 'ibios' class instead of Chart Component in your child component and use keyword 'super' to use parent methods.  Otherwise you can send it as props and use it
    class BarChartComponent extends Ibios{
      constructor(props){
            super(props)
            this.state={};  
        }
       componentDidMount(){
          //example
           var url="http://localhost:9090",apiUrl="/reports",prametrs={xyz:ramki};
         var retriveResponse=super.get(url,apiUrl,prametrs)
         console.log(retriveResponse);
       }
      render(){
         return(<p>hi......</p>);
      }
    }
