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。
插件源码：

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。
完整demo：
1 <!DOCTYPE html> 2 <html> 3 <head> 4
<meta charset="UTF-8"> 5
<script type="text/javascript" src="www.xdocin.com/xdoc.js?1.1.11"></script> 6
<script type="text/javascript" src="http://www.xdocin.com/baiduTemplate.js?1.1.11"></script> 7
<style> 8 .head{ 9 font-size: 29px;10 display: block;11 }12 .content{13 display: block;14 }15 </style>16 </head>17 <body>18 <input type="button" onclick="gen('pdf')" value="生成PDF"/>19 <input type="button" onclick="gen('docx')" value="生成Word"/>20 <br/>21 <script id="tmpl" type="text/html">22 <xdoc version="A.3.0">23 <body>24 <para heading="1" lineSpacing="28">25 <text class="head" valign="center" fontName="标宋" fontSize="29"><%=title%></text>26 </para>27 <para>28 <img src="<%=img%>" sizeType="autosize"/>29 </para>30 <para lineSpacing="9">31 <text class="content" fontName="仿宋" fontSize="18"><%=content%></text>32 </para>33 </body>34 </xdoc>35 </script>36 <script src="https://cdn.bootcss.com/jquery/2.2.4/jquery.js?1.1.11"></script>37 <script type="text/javascript">38 var type="docx";//pdf39 var data = {40 title: "导出"+type+"文件",41 img: "",42 content: "我这样就可以导出"+type+"格式的文件了，是不是很方便",43 };44 function renderTemplate(){45 var template=$("#tmpl").html();46 var html=template.replace(/<%=title%>/,data.title)47 .replace(/<%=img%>/,data.img)48 .replace(/<%=content%>/,data.content);49 $("body").append(html);50 }51 renderTemplate();52 function gen(type) {53 XDoc.to(baidu.template('tmpl', data), type, {}, "_blank");54 }55 console.log('');56 </script>57 </body>58 </html>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：
