【问题描述】：
我正在用 React 开发一个应用，我想使用 sidenav 组件http://materializecss.com/side-nav.html
问题是我收到了这个错误：
Sidebar.js:8 Uncaught TypeError: __WEBPACK_IMPORTED_MODULE_2_jquery___default(...)(...).sideNav is not a function
at HTMLDocument.<anonymous> (Sidebar.js:8)
at mightThrow (jquery.js:3534)
at process (jquery.js:3602)
我对导入组件、库的方式感到很困惑。它们有很多，并且有很多配置方法。
我所做的是：
-
使用
创建应用程序创建反应应用程序
-
通过 npm 安装实现
npm install materialize-css@next
创建反应应用
这是我正在使用的代码：
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta name="theme-color" content="#000000">
<link rel="manifest" href="%PUBLIC_URL%/manifest.json">
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
<title>React App</title>
</head>
<body>
<noscript>
You need to enable JavaScript to run this app.

<div id="root"></div>
<script type="text/javascript" src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script type="text/babel" src="js/materialize.min.js"></script>
</body>
</html>
App.js
import React from 'react'
import {BrowserRouter, Route} from 'react-router-dom';
import Sidebar from './Sidebar'
const Dashboard = () => <h2>Dashboard</h2>
const Survey = () => <h2>Survey</h2>
const Landing = () => <h2>Landing</h2>
const Home = () => <h2>Home</h2>
const App = () => {
return (
<div>
<BrowserRouter>
<div>
<Sidebar />
<Route exact path="/" component={Home} />
<Route path="/surveys" component={Dashboard} />
</div>
</BrowserRouter>
Hi There!
</div>
)
}
export default App;
Sidebar.js
import React, {Component} from 'react';
import 'materialize-css/dist/css/materialize.min.css';
import $ from 'jquery';
class Sidebar extends Component {
componentDidMount() {
$(document).ready(function(){
$('.sidenav').sideNav();
});
}
render() {
return (
<ul id="slide-out" className="sidenav">
<li><a href="#!"><i className="material-icons">cloud</i>First Link With Icon</a></li>
<li><a href="#!">Second Link</a></li>
</ul>
);
}
}
export default Sidebar;
package.json
{
"name": "support-tools",
"version": "0.1.0",
"private": true,
"dependencies": {
"jquery": "^3.3.1",

"scripts": {

"test": "react-scripts test --env=jsdom",

}
}
我尝试在 index.js 上使用两个版本的 jQuery
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
和
<script type="text/javascript" src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
但我可以让 sidenav 运行。我能做什么？
