本文主要是介绍Wabacus结合PDF.js实现在线文档预览，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
首先，我们需要了解一下什么是在线预览，能够实现文档在线预览的工具有很多，简单举一两个例子：
OpenOffice
该工具是实现了真正意义上的文档在线预览打印，因为它支持Office全部类型，包括图片在内。在预览的过程中，需要SWFTools将文件转换Adobe Flash文件（SWF文件），最终展示出来。虽然它展示的效果非常好，但个人觉得插件有点多，使用时还必须开启服务，整体来说比较麻烦。
启动OpenOffice服务：
C:cd C:\Program Files (x86)\OpenOffice 4\programsoffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizardOpenOfficeUnoServernetstat -anp tcp
WebOffice
支持全部Office菜单，支持Office2000(2003/2007/2010/2013/2016)以上版本的打印预览，也是一个非常不错的控件。
PDF.JS
相对于以上两种工具，PDFJS是在线预览PDF的一款神器。 对于PC端浏览器，一般直接提供pdf文件，iframe一下就可以直接预览PDF文档。
LibreOffice 6.1
LibreOffice是一款非常不错的文档转换工具，主要将不同类型的文档转换成PDF文件，可作为PDF.JS的辅助工具来使用。
