目录第一步：安装依赖：Jquery 和file-saver第二步：新增jquery.Wordexport.js第三步：组件使用Vue导出Word文件（模板方式）vue导出word文档
jquery.wordexport.js，通过该插件可以导出文本和图片，图片通过canvas的形式绘制，文本则需要依赖FileSaver.js插件。
FileSaver.js插件则主要通过H5的文件操作新特性new Blob()和new FileReader()来实现文本的导出。
npm install jquery file-saver --save在src下的assets中新增js文件夹，新增jquery.wordexport.js文件

</script>4.创建test.docx文档模板。注：使用vue-cli2的时候，放在static目录下；使用vue-cli3的时候，放在public目录下。
模板参数名需与字段一致，普通字段：{字段名}，图片字段：{%字段名}
