未定义 React 中的 Jquery

Hi I just want to receive ajax request, but the problem is that jquery is not defined in React. React version is 14.0

 Uncaught ReferenceError: $ is not defined

我有两个文件:

import React from 'react'; 
import { render } from 'react-dom';
import App from './containers/App';  

const root = document.getElementById('root');  

render( 
  <App source='https://api.github.com/users/octocat/gists' />, 
  root
);

app.js

import React, { Component } from 'react';

export default class App extends Component {

    componentDidMount() {
        const { source } = this.props;

        console.log($); // throws error
    }

    render() {
        return (
            <h1>Hey there.</h1>
        );
    }
}

推荐答案

尝试将 jQuery 添加到您的项目中，例如

npm i jquery --save

bower i jquery --save

import $ from 'jquery';
