PDF online preview, compatible with IE and CHROME

Http://files.cnblogs.com/w519/PDFViewSolution.rar

My PDF Online Preview DEMO uses pdfobject. js and adobe Reader.

Because PDFobjcet. js is not compatible with IE, pdfobjcet. js is used to open PDF in chrome, while adobe Reader is used to open PDF in IE.

Problem: expiration and other end extensions, which are downloaded by default and cannot be redirected to the page.

Method: you can remove the file extension in the url without downloading it!

1. Check the browser on the Default. aspx page. If it is IE and whether adobe Reader is installed, go to the preview view. aspx page and output a PDF file in the background. If chrome is used, use pdfobject. js to output a PDF file on this page.

Default. aspx code
