如何在Vue.js Webpack CLI项目中包含jQuery? [英] How to include jquery in a vuejs webpack cli project?

问题描述

您好，我曾经使用vuejs cli生成项目( https://github.com/vuejs/vue-cli ). cli使用webpack，在vue文件内部使用jquery时遇到问题.我总是得到一个.

Hello there i used to vuejs cli to generate a project (https://github.com/vuejs/vue-cli). The cli uses webpack and im having trouble using jquery inside of the vue files. Im always getting a.

http://eslint.org/docs/rules/no-undef  '$' is not defined

我尝试编辑我的webpack.dev.config以包括如下所示的provider插件块:

I have tried editing my webpack.dev.config to include the provide plugin block as follows:

var utils = require('./utils')
var webpack = require('webpack')
var config = require('../config')
var merge = require('webpack-merge')
var baseWebpackConfig = require('./webpack.base.conf')
var HtmlWebpackPlugin = require('html-webpack-plugin')
var FriendlyErrorsPlugin = require('friendly-errors-webpack-plugin')

// add hot-reload related code to entry chunks
Object.keys(baseWebpackConfig.entry).forEach(function (name) {
  baseWebpackConfig.entry[name] = ['./build/dev-client'].concat(baseWebpackConfig.entry[name])
})

module.exports = merge(baseWebpackConfig, {
  module: {
    rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap })
  },
  // cheap-module-eval-source-map is faster for development
  devtool: '#cheap-module-eval-source-map',
  plugins: [
    new webpack.DefinePlugin({
      'process.env': config.dev.env
    }),
    // https://github.com/glenjamin/webpack-hot-middleware#installation--usage
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin(),
    // https://github.com/ampedandwired/html-webpack-plugin
    new HtmlWebpackPlugin({
      filename: 'index.html',
      template: 'index.html',
      inject: true
    }),
    new FriendlyErrorsPlugin(),
    new webpack.ProvidePlugin({
      $ : "jquery",
      jQuery : "jquery"
    })
  ]
})

但是，当尝试使用jquery时，我一次又一次遇到相同的问题.我不反对为此使用CDN，无论我尝试什么，我真的都无法使这个想法包括jquery.

However when trying to use jquery i run into the same issues time and time again. Im not against using a cdn for this i really just cant get this think to include jquery no matter what i try.

如果vue文件很有帮助，我会尝试在脚本块内这样console.log $

If the vue file is helpful its i try to console.log $ like so inside the script block

<script>
export default {
  name: 'how_can_we_help_you',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  }
}
console.log($)
</script>

请帮助我，我非常困惑，并且一直在设法解决此问题.预先感谢.

Please help im very stuck and have been trying to fix this for quite a wile now. Thanks in advance.
