1、創(chuàng)建PropsChildren組件，代碼如下：

import React from 'react'

export default class PropsChildrenextends React.Component {
????state = {
????????x: 0,
????????y: 0
????}

????moveMouse = ?e => {
????????this.setState({
????????????x: e.clientX,
????????????y: e.clientY
????????})
????}

????componentDidMount() {
????????window.addEventListener('mousemove', this.moveMouse)
????}

????componentWillUnmount() {
????????window.removeEventListener('mousemove', this.moveMouse)
????}

????render() {
????????return this.props.render(this.state)
????}
}

2、組件運(yùn)用

import React from 'react'
import PropsChildren from './components/move-mouse/PropsChildren'

function App() {
????return (
????????<div className="App">
????????????<PropsChildren>
????????????????{
????????????????????move => {
????????????????????????return (<p>鼠標(biāo)當(dāng)前坐標(biāo)：{move.x}，{move.y}</p>)
????????????????????}
????????????????}
????????????</PropsChildren>
????)
}

export default App
