我想知道我们是否可以在HTML中添加多个react组件而不用通常通过npm下载相关文件,或者是否将其添加到普通HTML中,但是我们尝试为聊天应用添加某个组件,这是一个很长的示例:
<html lang="en">
<head>
<script src="https://unpkg.com/babel-standalone@6/babel.min.js"></script>
<script crossorigin src="https://unpkg.com/react@16/umd/react.development.js"></script>
<script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>
</head>
<body>
<div id="app"></div>
<script type="text/babel">
class App extends React.Component{
state={
messages:[
{ }
],
userId:''
}
addMessage=(message)=>{
message.num = Math.random();
message.id=this.state.messages.id;
let messages = [...this.state.messages, message];
this.setState({
messages })
}
addId=(userId)=>{
this.setState({
userId
})
}
render() {
return (
<div className="appContainer">
<User userId={this.addId} />
<TopSection Users={this.state.userId}/>
<Messages userId = {this.state.userId} messages={this.state.messages}/>
<AddMessage addMessage={this.addMessage} />
</div>
);
}
}
}
const Messages = ({messages, userId}) =>{
const messageList= (messages.length)? (messages.slice(1).map(message=>{
return(
<div className="message" key={message.num}>
<span key={userId.num}>{message.content?(userId):(null)}</span>
<p>{message.content}</p>
</div>
)
})) : (null);
return(
<div className="textContainer">
{messageList}
</div>
)
}
ReactDOM.render(<App />, document.getElementById('app'));
</script>
</body>
</html>
请让我知道是否有足够的空间使它工作。

您的意思是将组件添加到不同的dom节点吗?
import {render} from 'reactDOM'
import React from 'react'
import AppOne from './appOne'
import AppTwo from './appTwo'
render(<AppOne />, document.getElementById('appOne'));
render(<AppTwo />, document.getElementById('appTwo'));
