导入无法实现CSS JS响应

Good morning everyone,

大家早上好!

I've been struggling to get materialize css to work on my react-app, specifically, the Javascript files.

我一直在为实现css而努力，特别是Javascript文件。

I've tried multiple ways, but this is the one I think i've gotten farther.

我尝试了多种方法，但这是我认为我走得更远的方法。

In my 'landingpage.js' file:

在我的“landingpage。js文件:

import React, { Component } from 'react';
import './styles/css/custom.css';
import $ from 'jquery';
import 'materialize-css'; // It installs the JS asset only
import '../node_modules/materialize-css/js/modal';

The objective is to open a simple popup (so I can test if the JS is being imported correctly)

目的是打开一个简单的弹出窗口(这样我可以测试JS是否被正确导入)

            <div>
            <a class="waves-effect waves-light btn modal-trigger" href="#modal1">Modal</a>
            <div id="modal1" class="modal">
                <div class="modal-content">
                <h4>Modal Header</h4>
                <p>A bunch of text</p>
                </div>
                <div class="modal-footer">
                <a href="#!" class="modal-close waves-effect waves-green btn-flat">Agree</a>
                </div>
            </div>    
        </div>

So, as soon as the component mounts:

因此，一旦组件安装:

   componentDidMount() {
    $('.modal').modal();
}

When I click the button, it's supposed to open a popup, however:

当我点击按钮时，它应该会弹出:

ReferenceError: Component is not defined

This error occurs on the JS file i'm trying to import.

这个错误发生在我要导入的JS文件上。

I tried importing in many different ways and the app would not even recognize anything. I've been trying to import this for two days and searched the web a lot, I'm doing this for a School Final project, trying to self learn react.

我尝试了很多不同的导入方式，但这个应用甚至什么都认不出来。我花了两天的时间尝试导入它，在网上搜索了很多东西，我在学校的期末项目中做这个，尝试着自我学习反应。

Here's the link to the framework i'm trying to import:

Thank you for your time.

谢谢您的时间。

You need to add your full path from npm module into your entry point file for webpack to utilize your css...

您需要将npm模块的完整路径添加到您的入口点文件中，以便webpack使用您的css…

here is an example in a typical create-react-app using Index.js or what ever your calling it if you are doing your own react boilerplate.

下面是一个典型的创建-反应-应用程序使用索引的例子。如果你在做你自己的反应样板，你会怎么称呼它。

Index.js

Index.js

import React from 'react';
import ReactDOM from 'react-dom';
import 'materialize-css/dist/css/materialize.min.css'; // <---

import App from './components/App';

ReactDOM.render(<App />, document.getElementById('root'));

Once this is done your components will be able to have access to the css properties. I also recommend you install the npm i -S materialize-css@next so you can use JS components without needing JQuery

完成之后，您的组件将能够访问css属性。我还建议您安装npm I -S materialize-css@next，以便不需要JQuery就可以使用JS组件

using jquery with react is not recommended at all if you trying to use material how about using a library like

如果您试图使用类似库的材料，那么完全不建议使用jquery和react

material-ui install it by using

材料-ui通过使用来安装

npm i material-ui --save

and you can follow the example here for dialog which is basically a modal dialog in material ui

你可以按照这里的例子进行对话它基本上是一个模态对话框
