用pdf.js试试吧
pdf.js怎么用,能给个小例子么
@gnail_oug:
直接使用的例子
<html> <body> <div> <button id="prev" onclick="goPrevious()">Previous</button> <button id="next" onclick="goNext()">Next</button> <span>Page: <span id="page_num"></span> / <span id="page_count"></span></span> </div> <div> <canvas id="the-canvas" style="border:1px solid black"></canvas> </div> <!-- Use latest PDF.js build from Github --> <script type="text/javascript" src="https://raw.github.com/mozilla/pdf.js/gh-pages/build/pdf.js"></script> <script type="text/javascript"> // // NOTE: // Modifying the URL below to another server will likely *NOT* work.

@gunsmoke: 请问这个用远程地址的pdf文件就加载不上,你这边行吗?
在Android和PC浏览器中都不行,如果是本地的pdf文件是可以的。但以http开头的不行。
@简单--生活: 代码用 firefox 本地或远程都可以,但用 chrome 都不行。但http://mozilla.github.io/pdf.js/web/viewer.html 两个浏览器都用。
