jquery.wordexport.js依赖jquery；
首先npm i jquery file-saver --save；
引入jquery
首先在根目录下创建vue.config.js
vue.config.js

const webpack = require('webpack')
module.exports = {
    //lintOnSave: false,
    configureWebpack: {
        //支持jquery
        plugins: [
            new webpack.ProvidePlugin({
                $: "jquery",
                jQuery: "jquery",
                "windows.jQuery": "jquery"
            })
        ]
    },
};

创建FileSaver.js和jquery.wordexport.js两个文件，一般放到assets下面的js目录下；
