使用来自typescript的javascript,使用webpack进行捆绑。运行时错误

我有一个简单的javascript函数:

function alphanum(a, b) {
  function chunkify(t) {
    var tz = [], x = 0, y = -1, n = 0, i, j;

    while (i = (j = t.charAt(x++)).charCodeAt(0)) {
      var m = (i == 46 || (i >=48 && i <= 57));
      if (m !== n) {
        tz[++y] = "";
        n = m;
      }
      tz[y] += j;
    }
    return tz;
  }

  var aa = chunkify(a);
  var bb = chunkify(b);

  for (x = 0; aa[x] && bb[x]; x++) {
    if (aa[x] !== bb[x]) {
      var c = Number(aa[x]), d = Number(bb[x]);
      if (c == aa[x] && d == bb[x]) {
        return c - d;
      } else return (aa[x] > bb[x]) ? 1 : -1;
    }
  }
  return aa.length - bb.length;
}

这是在alphanum.js。

我想在打字稿文件中使用它。所以我做了以下事情:

declare function alphanum(param1: any, param2: any): number;
require("./../utils/alphanum.js");

我正在使用webpack将所有内容捆绑在一起。这似乎很好,没有错误,没有问题。

当我尝试使用该功能时,我在客户端上出现错误:

EXCEPTION: ReferenceError: alphanum is not defined

我觉得我错过了一些非常明显的东西。我是否在使用webpack做错了什么并且要求?

编辑:

这是我的webpack配置:

webpack.common.js:

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var helpers = require('./helpers');

module.exports = {
  entry: {
    'polyfills': './src/polyfills.ts',
    'vendor': './src/vendor.ts',
    'app': './src/main.ts'
  },

  resolve: {
    extensions: ['', '.js', '.ts'],
    root: [
      helpers.root('./src'),
      helpers.root('node_modules')
    ],
     alias: {
      // bind version of jquery-ui
      "jquery.ui.core": "jqueryui/jquery-ui.min.js",     
      "jquery.ui.widget": "jqueryui/jquery-ui.min.js"
     }
  },

  module: {
    loaders: [
      {
        test: /\.ts$/,
        loaders: ['ts', 'angular2-template-loader']
      },
      {
        test: /\.html$/,
        loader: 'html'
      },
      {
        test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
        loader: 'file?name=assets/[name].[hash].[ext]'
      },
      {
        test: /\.css$/,
        exclude: helpers.root('src', 'app'),
        loader: ExtractTextPlugin.extract('style', 'css?sourceMap')
      },
      {
        test: /\.css$/,
        include: helpers.root('src', 'app'),
        loader: 'raw'
      }
    ]
  },

  plugins: [
    new webpack.optimize.CommonsChunkPlugin({
      name: ['app', 'vendor', 'polyfills']
    }),

    new HtmlWebpackPlugin({
      template: 'src/index.html'
    }),

    new webpack.ProvidePlugin({
      jQuery: 'jquery',
      $: 'jquery',
      jquery: 'jquery',
      "window.jQuery":"jquery"})
  ]
};

webpack.dev.js:

var webpackMerge = require('webpack-merge');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var commonConfig = require('./webpack.common.js');
var helpers = require('./helpers');

module.exports = webpackMerge(commonConfig, {
  devtool: 'source-map',
  debug: true,

  output: {
    path: helpers.root('dist'),
    publicPath: 'http://localhost:8080/',
    filename: '[name].js',
    chunkFilename: '[id].chunk.js'
  },

  plugins: [
    new ExtractTextPlugin('[name].css')
  ],

  devServer: {
    historyApiFallback: true,
    stats: 'minimal'
  }
});

tsconfig.json:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": true,
    "suppressImplicitAnyIndexErrors":true,
    "outDir": "dist"
  },
  "exclude": [
    "node_modules",
    "typings/main",
    "typings/main.d.ts"
  ]
}

这是一个Angular2应用程序,如果有帮助,webpack配置主要来自:https://angular.io/docs/ts/latest/guide/webpack.html

ReferenceError:未定义alphanum

默认情况下,webpack会将每个文件视为模块。您将其用作global

修复

如果你仍然希望它全球化,你会:

function alphanum(a, b) {
  function chunkify(t) {
    var tz = [], x = 0, y = -1, n = 0, i, j;

    while (i = (j = t.charAt(x++)).charCodeAt(0)) {
      var m = (i == 46 || (i >=48 && i <= 57));
      if (m !== n) {
        tz[++y] = "";
        n = m;
      }
      tz[y] += j;
    }
    return tz;
  }

  var aa = chunkify(a);
  var bb = chunkify(b);

  for (x = 0; aa[x] && bb[x]; x++) {
    if (aa[x] !== bb[x]) {
      var c = Number(aa[x]), d = Number(bb[x]);
      if (c == aa[x] && d == bb[x]) {
        return c - d;
      } else return (aa[x] > bb[x]) ? 1 : -1;
    }
  }
  return aa.length - bb.length;
}

// THIS IS WHERE THE MAGIC HAPPENS
global.alphanum = alphanum;

您缺少从alphanum.js导出您的函数,这就是为什么它未定义。

export function alphanum(a, b) { 

来自你的alphanum.js它应该可以工作。
