Pass pdf url to pdf.js in query string

Try adding ?file=document.pdf to the viewer url. See also https://github.com/mozilla/pdf.js/issues/2496

It will require some changes in the viewer.js:

Move parseQueryString: function pdfViewParseQueryString(query) outside var PDFView so it's a standalone function: function pdfViewParseQueryString(query)
Replace all occurences of PDFView.parseQueryString(..) to pdfViewParseQueryString(..)
Change var DEFAULT_URL = '' to var urlParm = pdfViewParseQueryString(document.location.search.substring(1)); var DEFAULT_URL = urlParm.url;
You should now be able to call the viewer with somethin like $("actualViewer").src = 'pdfViewer?url=' + encodeURIComponent(pathToFile);

On a further note, it is important to know that the file=document.pdf argument must come before the hash sign:
