複製代碼
這種方式在新版本react是走不通的,須要像下面這種操做javascript
import React, {Component} from 'react';
export default class Parent extends Component {
render() {
return(
<div> <Child onRef={this.onRef} /> <button onClick={this.click} >click</button> </div> ) } 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') } } 複製代碼
