React.js refs 和props传递数据

import React from 'react';
import { Button} from 'antd';

///子组件
var HelloMessage = React.createClass({
  childMethod: function(){
    alert("组件之间通信成功");
  },
  render: function() {
    return <div> <h1>Hello {this.props.name}</h1> <Button onClick={this.childMethod}>子组件</Button></div>
  }
});

//父组件
var ImDaddyComponent = React.createClass({
  getDS: function(){
    //调用组件进行通信
    this.refs.getButton.childMethod();
  },
  render: function(){
    return (
      <div>
        <HelloMessage name="John" ref="getButton" />
        <Button onClick={this.getDS}>父组件</Button>
      </div>
    );
  }
});

export default class Home extends React.Component {
  render() {
    return (
      <ImDaddyComponent/>
    );
  }
}

点击父组件按钮可以调用到子组件的方法，

<HelloMessage name="John" ref="getButton" />

通过{this.props.name}，name被传递到了HelloMessage上

运行结果：
