前言：

项目开发中遇到了需要将HTML页面的内容导出为一个word文档，所以有了这边随笔。

当然，项目开发又时间有点紧迫，第一时间想到的是用插件，所以百度了下。下面就介绍两个导出word文档的方法。

法一：通过jquery.wordexport.js导出word

备注：兼容IE9以上

大概浏览了下jquery.wordexport.js插件的代码，了解到了通过该插件可以导出文本和图片，而图片首先通过canvas的形式

绘制，文本则需要再依赖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。

直接调用wordExport()接口就可以导出word文档，传的参数为导出的word文件名。

补充：

通过我们常规写的外联样式设置样式是无效的，通过个人的实践发现需要写内联样式才能生效，而单位也需要按照word的配置

单位pt设置。

而jquery.wordexport.js插件是要配置了个style样式让我们补充样式设置的：

但是个人实践了下，设置的样式却无法生效，只能通过内联设置才生效。

法二：通过百度js模板引擎生成word文档

主要是通过js模板设置对应的标签，然后XDoc.to(baidu.template())导出word，而通过百度js模板引擎的好处是也可以导出PDF文件。

这里我通过renderTemplate函数叫js模板渲染到HTML中，实现了文本的展示和导出内容的结合。而因为这里导出的word文档是需要特别设置样式的，所以在页面样式展示下我们可以通过添加.class的方式设置。

附部分导出word文档样式设置：
