React html中使用react的兩種方式

Posted on by

基本使用

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>hello</title>
</head>

<body>
  <div id="app">

  </div>
  <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>
  <script type="text/babel">
    // 虛擬dom
    const str = 'hello react'
    const vDom = <h1>{str}</h1>
    // const vDom = <pppp>hello react</pppp>
    // 把虛擬dom轉化成真實的dom
    ReactDOM.render(vDom,document.getElementById("app"))
  </script>
</body>

</html>

創建虛擬dom的兩種方式

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>hello</title>
</head>

<body>
  <div id="app">

  </div>
  <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>
  <script>
    // 第一種純js創建(一般不用)
    // 虛擬dom
    const str = 'hello react'
    const vDom = React.createElement('h1', {
      id: 'myId'
    }, str)
    // const vDom = <pppp>hello react</pppp>
    // 把虛擬dom轉化成真實的dom
    ReactDOM.render(vDom, document.getElementById("app"))
    // 
  </script>
</body>

</html>
<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>hello</title>
</head>

<body>
  <div id="app">

  </div>
  <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>
  <script type="text/babel">
    // 第一種純js創建(一般不用)
    // [] ul li 用forEach實現
    var names = ['張飛','關羽','趙雲']
    const ul = <ul>
      {
        names && names.map((name,index)=>
          <li key={index}>
            {name}
          </li>
        )
      }
    </ul>
    ReactDOM.render(ul,document.getElementById("app"))
    // 
  </script>
</body>

</html>

知識點擴展：

React pwa的配置

在到webpack配置文件中添加插件

const WorkboxWebpackPlugin = require('workbox-webpack-plugin')
plugins: [
    new MiniCssExtractPlugin({
      filename: '[name].css'
    }),
    new WorkboxWebpackPlugin.GenerateSW({
      clientsClaim:true,
      skipWaiting:true
    })
  ],
