站长资讯网前言：
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。
插件源码：

插件调用：
1 <!DOCTYPE html> 2 <html> 3 <head lang="en"> 4 <meta charset="UTF-8"> 5 <title>生成word文档</title> 6 </head> 7 <body lang=ZH-CN style='tab-interval:21.0pt'> 8 <p class="word"> 9 <p align="center" style="font-size:20pt;font-weight:bold;">JS导出Word文档</p> 10 </p> 11 <input type="button" value="导出word"> 12 <script src="https://cdn.bootcss.com/jquery/2.2.4/jquery.js?1.1.11"></script> 13 <script type="text/javascript" src="js/FileSaver.js?1.1.11"></script> 14 <script type="text/javascript" src="js/jquery.wordexport.js?1.1.11"></script> 15 <script> 16 $(function(){ 17 $("input[type='button']").click(function(event) { 18 $(".word").wordExport('生成word文档'); 19 }); 20 }) 21 </script> 22 </body> 23 </html>
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。
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";//pdf 39 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：
