16.3.0之前的设置方法为

var HelloMessage = React.createClass({    childMethod: function(){        alert("组件之间通信成功");    },    render: function() {        return 
      
 
       
Hello {
    this.props.name}
  
       子组件
      
    }});// 父组件var ImDaddyComponent = React.createClass({    getDS: function(){        // 调用组件进行通信        this.refs.getSwordButton.childMethod();    },    render: function(){        return (                
      
                    
                           
       父组件                
      
        );    }});ReactDOM.render(        
      ,        document.getElementById('correspond'));

import React, {Component} from 'react';export default class Parent extends Component {    render() {        return(            
      
                
                       
       click            
      
        )    }    onRef = (ref) => {        this.child = ref    }    click = (e) => {        this.child.myName()    }}class Child extends Component {    componentDidMount(){        this.props.onRef(this)    }    myName = () => alert('xiaohesong')    render() {        return ('woqu')    }}
