首先按照官方文档一分钟用上React以及快速尝试JSX，如果你不需要JSX，可以按照这个Demo去实现

我们在页面上放入这三个cdn：

代码语言：javascript复制
<script crossorigin src="https://unpkg.com/react@16/umd/react.production.min.js"></script>
<script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/babel-standalone@6/babel.min.js"></script>

然后新建一个script标签并指定type="text/babel"，例如：

代码语言：javascript复制
<script src="ruben.js" type="text/babel"></script>

然后我们编写代码

代码语言：javascript复制
<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8" />
    <title>Add React in One Minute</title>
  </head>
  <body>

    <h2>Add React in One Minute</h2>
    <p>This page demonstrates using React with no build tooling.</p>
    <p>React is loaded as a script tag.</p>

    <!-- We will put our React component inside this div. -->
    <div id="like_button_container"></div>

    <div id="filterable_product_table"></div>

    <!-- Load React. -->
    <!-- Note: when deploying, replace "development.js" with "production.min.js". -->
    <script src="https://unpkg.com/react@17/umd/react.development.js" crossorigin></script>
    <script src="https://unpkg.com/react-dom@17/umd/react-dom.development.js" crossorigin></script>
    <script src="https://unpkg.com/babel-standalone@6/babel.min.js" crossorigin></script>

    <!-- Load our React component. -->
    <script src="ruben.js" type="text/babel"></script>
  </body>
</html>

ruben.js：

代码语言：javascript复制
'use strict';

function LikeButton() {
    const [liked, setLiked] = React.useState(false)
    if (liked) {
        return 'You liked this.';
    }
    return (
        <button onClick={() => setLiked(true)} >
            Like
        </button>
    );
}
ReactDOM.render(<LikeButton />, document.querySelector('#like_button_container'))

然后就可以预览看看效果啦！

点击按钮后，state变为了true，且页面也发生了对应变化
