React项目中的Bootstrap需要jQuery [英] jQuery needed for Bootstrap in React project

问题描述

我正在开发一个React.js项目，而不是使用React-Bootstrap，我将Bootstrap的CSS加载到我的项目中。我现在需要导入jQuery，以便我可以使用下拉菜单等。

I am developing a React.js project where instead of using React-Bootstrap, I am loading the CSS of Bootstrap into my project. I am now needing to import the jQuery so that I can use dropdown menus etc.

入口点文件（index.js） - 希望它能正常工作

Entry point file (index.js) - in the hope it would work

'use strict'
import React from 'react'
import { Route, Router, IndexRoute, browserHistory } from 'react-router'
import { render } from 'react-dom'

// Pages
import Main from './pages/main/main'
import Home from './pages/home/home'
import About from './pages/about/about'
window.jQuery = window.$ = require('jquery/dist/jquery.min')
import '../node_modules/bootstrap/dist/css/bootstrap.min.css'
import '../node_modules/bootstrap/dist/js/bootstrap.min.js'

render((
  <Router history={browserHistory}>
    <Route name='home' path='/' component={Main}>
      <IndexRoute component={Home} />
      <Route name='about' path='about' component={About} />
    </Route>
  </Router>), document.getElementById('app'))

Webpack文件

'use strict'
const path = require('path')
const webpack = require('webpack')

module.exports = {
  entry: [
    './browser/index'
  ],
  output: {
    path: path.join(__dirname, 'public', 'js'),
    filename: 'bundle.js',
    publicPath: '/public/js/'
  },
  plugins: [
    new webpack.ProvidePlugin({
      $: 'jquery',
      jQuery: 'jquery'
    }),
    new webpack.NoErrorsPlugin()
  ],
  module: {
    loaders: [
      { test: /\.js$/,
        loader: 'babel-loader',
        query: {
          presets: [ 'es2015', 'react' ]
        },
        include: path.join(__dirname, 'browser')
      },
      { test: /\.css$/, loader: 'style-loader!css-loader' },
      {test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: 'file'},
      {test: /\.(woff|woff2)$/, loader: 'url?prefix=font/&limit=5000'},
      {test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=application/octet-stream'},
      {test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=image/svg+xml'},
      { test: require.resolve('jquery'), loader: 'imports?jQuery=jquery' }
    ]
  }
}

Chrome Dev工具中出现错误：'Bootstrap的Javascript需要jQuery'。我想知道是否我在webpack文件中的加载器方面缺少某些东西，或者在条目文件中需要import语句？

The error appears in Chrome Dev tools: 'Bootstrap's Javascript requires jQuery'. I'm wondering whether perhaps I am missing something in terms on loaders in the webpack file, or need an import statement in the entry file?

推荐答案

请确保已安装'imports-loader'，（npm install --save imports-loader）。在module.exports中试试这个：

Please make sure you have installed 'imports-loader', (npm install --save imports-loader). And in module.exports try this:

{ test: /bootstrap.+\.(jsx|js)$/, loader: 'imports?jQuery=jquery,$=jquery,this=>window' }
