在Html页面直接展示pdf文件

使用js文件

js文件下载链接：https://github.com/pipwerks/PDFObject/
样例：

1. Create a container to hold your PDF

<div id="example1"></div>

2. Tell PDFObject which PDF to embed, and where to embed it

<script src="/js/pdfobject.js"></script>
<script>PDFObject.embed("/pdf/sample-3pp.pdf", "#example1");</script>
