Dynamically assign PDF file paths to the viewer

[msepahvand]

I was wondering of there is any way for me to dynamically change the path of the PDF file referenced inside viewer.js? Inside my viewer.js right now I have:

var DEFAULT_URL = './MyPDFs/test1.pdf';

Obviously this is the link to the PDF I'm displaying. My question is: can I dynamically change that link (DEFAULT_URL) server side? I'm trying to implement a functionality whereby the user clicks on an entry in a table, I then retrieve the PDF related to that entry from the database, make a copy of it server side and assign the URL of that newly created PDF to the viewer.

Is this possible? If so how would I go about doing it? Thanks for any help, this project is so awesome.

pass it as the '?file=' param, e.g. http://mozilla.github.com/pdf.js/web/viewer.html?file=http%3A%2F%2Fasync5.org%2Fmoz%2Fpdfjs.pdf

Hi, Can anyone of you be more descriptive about the solution. Will this method work with local storage url too?

Will this method work with local storage url too?

How would you pass a base64 data instead of the url within javascript?
"data:application/pdf;base64,JVBERi0x..";

[yurydelendik]

@henry-mac see http://stackoverflow.com/questions/12092633/pdf-js-rendering-a-pdf-file-using-a-base64-file-source-instead-of-url

[henry-mac]

Thanks yurydelendik, I saw that link earlier. However, it only produces one page similar to the helloworld example. I want to be able to use all the features and functionality such as zoom,print,pages, of the http://mozilla.github.io/pdf.js/web/viewer.html.

[yurydelendik]

btw, http://mozilla.github.io/pdf.js/web/viewer.html?file=data:application/pdf;base64,JVBERi0xLjcKCjEgMCBvY...U9G works for me in Firefox.

Also, I know that some browsers (e.g. Internet Explorer) truncate long URLs so you will be able to send only small PDFs.

[henry-mac]

This is great, I see it works in firefox now too. But it doesn't work in chrome which I do most of my development in because I have "-args --allow-file-access-from-files --disable-xss-auditor --disable-web-security". Also, I hope this will work on the ipad. Thanks for your help yurydelendik.

Please guide me.

This is PDF.js, not ViewerJS. For ViewerJS support go to https://github.com/kogmbh/ViewerJS.

Hello guys I've been searching around for a solution to my issue but I can't find anything I can use.The tool works great when I point to an existing pdf file. However, I'm having issues when I call a .net MVC controller to return a dynamically generated File of type "pdf". For Example: /web/viewer.html?file=URL (to my asp.net controller) Any suggestions would be greatly appreciated.

[whadla]

Tim thanks for pointing us to ViewerJS. I found my solution here: webodf/ViewerJS#27

"ViewerJS 0.5.5 got released today, and it improves situation around content type detection. It both tries to query to server for the mimetype initially and also can be passed the type as argument in the passed url, e.g. /ViewerJS/index.html?type=pdf#http://mypage.com/service/createpdf
That should solve this problem, so closing this issue." -kossebau

Hopefully this will help anyone that's facing the same issue.
