在 HTML 页面中使用 React

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</>

    meta charset="utf-8" />
    http-equiv="X-UA-Compatible" content="IE=edge"name="viewport"="width=device-width,initial-scale=1"link rel="stylesheet" href="libs/antd/antd.min.css"="css/index.css"style type="text/css"stylescript ="text/javascript" src="libs/jquery-1.9.1.js"></script="libs/react/react.production.min.js"="libs/react/react-dom.production.min.js"="libs/babel/babel.min.js"="libs/moment/moment-with-locales.min.js"="libs/antd/antd-with-locales.min.js"bodyinput id='btn' ="button" class="index-btn" value="显示React组件" />

    ="text/babel"="components/HelloReact.jsx"="module"="index.js"html>

View Code

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 = this).val('显示React组件');
    }
});

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 },1)">this.componentProps))
            ),document.getElementById(.componentContainerId)
        );
    }

    show() {
        this.render();
    }

    hide() {
        );
    }

}

export { ReactComponentContainer }

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(.dateFormat),timeStr: moment(now).format(.timeFormat)
        }

        this.onChangeDate = this.onChangeDate.bind();
        this.onChangeTime = this.onChangeTime.bind(this.updateDatePickerAndTimePicker = this.updateDatePickerAndTimePicker.bind();
    }

    onChangeDate(date,dateString) {
        .setState({ dateStr: dateString });
    }

    onChangeTime(time,timeString) {
        .setState({ timeStr: timeString });
    }

    updateDatePickerAndTimePicker() {
        let now =  Date().valueOf();
        .setState({
            dateStr: moment(now).format(.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,1)">this.dateFormat)} />
            &nbsp;
            <antd.TimePicker onChange={this.onChangeTime} value={moment(this.state.timeStr,1)">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>;
    }
}

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
