【React学习】—React中的事件绑定（八）
一、原生JS
<body><button id="btn1">按钮1</button><button id="btn2">按钮2</button><button onclick="demo()">按钮3</button><script>const btn1 = document.getElementById("btn1");btn1.addEventListener("click", () => {alert("按钮1被点击了");});const btn2 = document.getElementById("btn2");btn2.onclick = () => {alert("按钮2被点击了");};function demo() {alert("按钮3被点击了");}</script></body>
二、React中的事件绑定
<script type="text/babel">class Weather extends React.Component {constructor(props) {super(props);this.state = { isHot: false };}render() {return (<h1 onClick={demo}>今天天气很{this.state.isHot ? "炎热" : "凉爽"}</h1>);}}ReactDOM.render(<Weather />, document.getElementById("test"));function demo() {console.log("标题被点击了");}</script>
