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:
