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：

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。

41 img: "",

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);

53 xdoc.to(baidu.template('tmpl', data), type, {}, "_blank");

55 console.log('');

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：
