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。
