Vue项目中使用bootstrap

一、安装jQuery

Bootstrap需要依赖jQuery，所以引用Bootstrap之前要先引用jQuery，使用下面的命令引用jQuery：

npm install jquery --save

二、引入Bootstrap

1、使用命令安装

npm install bootstrap --save

2、下载Bootstrap文件

直接去Bootstrap下载bootstrap包，把下载好的文件放到src/assets目录下面：

三、配置使用jQuery

1、添加webpack

在build/webpack.base.conf.js文件的顶部添加下面的代码：

const webpack=require("webpack")

2、修改webpack.base.conf.js

在build/webpack.base.conf.js文件中，在整个配置对象的末尾增加plugins配置：

// 配置全局使用 jquery
plugins: [
    new webpack.ProvidePlugin({
    $: "jquery",
    jQuery: "jquery",
    jquery: "jquery",
    "window.jQuery": "jquery"
})]

build/webpack.base.conf.js完整代码如下：

'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
const webpack=require("webpack")
function resolve (dir) {
  return path.join(__dirname, '..', dir)
}

// const createLintingRule = () => ({
//   test: /\.(js|vue)$/,
//   loader: 'eslint-loader',
//   enforce: 'pre',
//   include: [resolve('src'), resolve('test')],
//   options: {
//     formatter: require('eslint-friendly-formatter'),
//     emitWarning: !config.dev.showEslintErrorsInOverlay
//   }
// })

module.exports = {
  context: path.resolve(__dirname, '../'),
  entry: {
    app: './src/main.js'
  },
  output: {
    path: config.build.assetsRoot,
    filename: '[name].js',
    publicPath: process.env.NODE_ENV === 'production'
      ? config.build.assetsPublicPath
      : config.dev.assetsPublicPath
  },
  resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: {
      'vue$': 'vue/dist/vue.esm.js',
      '@': resolve('src')
    }
  },
  module: {
    rules: [
      // 关闭eslint编码规范验证
      // ...(config.dev.useEslint ? [createLintingRule()] : []),
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: vueLoaderConfig
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')]
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('media/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
        }
      }
    ]
  },
  node: {
    // prevent webpack from injecting useless setImmediate polyfill because Vue
    // source contains it (although only uses it if it's native).
    setImmediate: false,
    // prevent webpack from injecting mocks to Node native modules
    // that does not make sense for the client
    dgram: 'empty',
    fs: 'empty',
    net: 'empty',
    tls: 'empty',
    child_process: 'empty'
  },
  // 配置全局使用 jquery
  plugins: [
    new webpack.ProvidePlugin({
    $: "jquery",
    jQuery: "jquery",
    jquery: "jquery",
    "window.jQuery": "jquery"
  })]
}

四、在main.js中引用

// 引入jQuery
import $ from 'jquery'
// 引用bootstrap
import './assets/bootstrap-3.3.7-dist/css/bootstrap.css'
import './assets/bootstrap-3.3.7-dist/js/bootstrap.js'

五、测试

<template>
  <div>
      <p class="col-md-6">
         <button class="btn btn-primary">测试按钮</button>
      </p>
  </div>

</template>

<script>
export default {
  name:"test",
}
</script>
