は、私は、次のエラーを取得：複数のエラー
bundle.js:1079 Warning: render(): Rendering components directly into document.body is discouraged, since its children are often manipulated by third-party scripts and browser extensions. This may lead to subtle reconciliation issues. Try rendering into a container element created for your app.printWarning @ bundle.js:1079warning @ bundle.js:1103_renderSubtreeIntoContainer @ bundle.js:11201render @ bundle.js:11271181../components/LoginForm/index.jsx @ bundle.js:20603s @ bundle.js:1e @ bundle.js:1(anonymous function) @ bundle.js:1
bundle.js:1079 Warning: render(): Target node has markup rendered by React, but there are unrelated nodes as well.

bundle.js:1079 Warning: React attempted to reuse markup in a container but the checksum was invalid. This generally means that you are using server rendering and the markup generated on the server was not what the client was expecting. React injected new markup to compensate which works but you have lost many of the benefits of server rendering. Instead, figure out why the markup being generated is different on the client or server:

私は私はかなり貧弱であると言わなければならない反応チュートリアルhttps://facebook.github.io/react/tutorial/tutorial.htmlに従うことをしようとしています。また、ネット上に存在するチュートリアルには、廃止されたメソッドなどを使用するいくつかの異なるバージョンが混在しています。それはジャングルです！ index.jsファイル内
'use strict';
import React from 'react';
export default class LoginForm extends React.Component {
constructor(props) {
super(props);
this.state = { isToggleOn: true };
this.submitFormClick = this.submitFormClick.bind(this);
}
submitFormClick(e) {
e.preventDefault();
this.setState(prevState => ({
isToggleOn: !prevState.isToggleOn
}));
}
render() {
return (
<div>{this.state.isToggleOn ? 'TRUE TOGGLE' : 'FALSE TOGGLE'}
<form role="form" onSubmit="">
<input type="text" name="username" />
<br />
<input type="password" name="password" />
<br />
<button onClick={this.submitFormClick}>Login</button>
</form>
</div>
);
}
}
入場方法：
方法をレンダリング
ReactDOM.render(<App />, document.getElementById('root'));
main.htmlと：
<html>
<head>
<meta charset="utf-8" />
<title>index.html</title>
</head>
<body>
<div id="root"></div>
<script src="static/bundle.js"></script>
</body>
</html>
私はそれをサーバー側レンダリング方法：
をconst App = React.createFactory(AppComponent);
const html = ReactDOMServer.renderToString(App({}));
res.setHeader('Content-Type', 'text/html; charset=utf-8');
res.status(200)
.send(html);
