- 本文通过案例场景分析给大家介绍在 HTML 页面中使用 React的代码,react组件不是按需加载,只适合小型应用,本文给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友参考下吧
复制代码
该方案使用场景:在html页面中使用react,主js文件index.js和其它非react功能使用js模块化的方式开发,适合轻量级中小型应用
index.html代码:
引入react、react-dom、babel、moment、antd等
- <!DOCTYPE html>
- <html lang='zh-CN'>
- <head>
- <title>React in HTML</title>
- <meta charset="utf-8" />
- <meta http-equiv="X-UA-Compatible" content="IE=edge">
- <meta name="viewport" content="width=device-width, initial-scale=1">
- <link rel="stylesheet" href="libs/antd/antd.min.css">
- <link rel="stylesheet" href="css/index.css">
- <style type="text/css">
- </style>
- <script type="text/javascript" src="libs/jquery-1.9.1.js"></script>
- <script type="text/javascript" src="libs/react/react.production.min.js"></script>
- <script type="text/javascript" src="libs/react/react-dom.production.min.js"></script>
- <script type="text/javascript" src="libs/babel/babel.min.js"></script>
- <script type="text/javascript" src="libs/moment/moment-with-locales.min.js"></script>
- <script type="text/javascript" src="libs/antd/antd-with-locales.min.js"></script>
- </head>
- <body>
- <input id='btn' type="button" class="index-btn" value="显示React组件" />
- <script type="text/babel" src="components/HelloReact.jsx"></script>
- <script type="module" src="index.js"></script>
- </body>
- </html>
复制代码
index.js代码:
- import { ReactComponentContainer } from './ReactComponentContainer.js'
- let isShow = true;
- let helloReactContainer;
- $('#btn').on('click', function () {
- if (isShow) {
- helloReactContainer = new ReactComponentContainer('helloReact', HelloReact, { name: 'React' });
- helloReactContainer.show();
- isShow = false;
- $(this).val('隐藏React组件');
- } else {
- helloReactContainer.hide();
- isShow = true;
- $(this).val('显示React组件');
- }
- });
复制代码
ReactComponentContainer.js代码:
该模块用于在html中显示隐藏react组件
- class ReactComponentContainer {
- component
- componentProps
- componentContainerId
- constructor(componentContainerId, component, componentProps) {
- if ($('#' + componentContainerId).length == 0) {
- $('body').append('<div id="' + componentContainerId + '"></div>');
- }
- this.componentContainerId = componentContainerId;
- this.component = component;
- this.componentProps = componentProps;
- }
- render(isShow) {
- ReactDOM.render(
- React.createElement(
- antd.ConfigProvider,
- {
- locale: antd.locales.zh_CN
- },
- React.createElement(this.component, Object.assign({ isShow: isShow }, this.componentProps))
- ),
- document.getElementById(this.componentContainerId)
- );
- }
- show() {
- this.render(true);
- }
- hide() {
- this.render(false);
- }
- }
- export { ReactComponentContainer }
复制代码
HelloReact.jsx代码:
- class HelloReact extends React.Component {
- dateFormat = 'YYYY-MM-DD'
- timeFormat = 'HH:mm:ss'
- constructor(props) {
- super(props);
- let now = new Date().valueOf();
- this.state = {
- dateStr: moment(now).format(this.dateFormat),
- timeStr: moment(now).format(this.timeFormat)
- }
- this.onChangeDate = this.onChangeDate.bind(this);
- this.onChangeTime = this.onChangeTime.bind(this);
- this.updateDatePickerAndTimePicker = this.updateDatePickerAndTimePicker.bind(this);
- }
- onChangeDate(date, dateString) {
- this.setState({ dateStr: dateString });
- }
- onChangeTime(time, timeString) {
- this.setState({ timeStr: timeString });
- }
- updateDatePickerAndTimePicker() {
- let now = new Date().valueOf();
- this.setState({
- dateStr: moment(now).format(this.dateFormat),
- timeStr: moment(now).format(this.timeFormat)
- });
- }
- render() {
- return <div style={{ display: this.props.isShow ? '' : 'none' }}>
- <h1>Hello {this.props.name}, Now is {this.state.dateStr} {this.state.timeStr}</h1>
- <antd.DatePicker onChange={this.onChangeDate} value={moment(this.state.dateStr, this.dateFormat)} />
-
- <antd.TimePicker onChange={this.onChangeTime} value={moment(this.state.timeStr, this.timeFormat)} />
- <br />
- <antd.Button type="primary" size="default" style={{ marginTop: '10px' }} onClick={this.updateDatePickerAndTimePicker} >更新日期时间控件值</antd.Button>
- </div>;
- }
- }
复制代码
效果图:
浏览器按F12弹出DevTools,在Sources选项卡中可以看到组件代码,方便打断点调试
遇到的问题:
无法使用es6的import语法导入react组件,es6的import和require.js都不认识jsx
react组件不是按需加载,只适合小型应用
