I'm using PDF.Js to embed PDF file for preview, and I removed the script of download and open files from the viewer.js , but when I test the page and PDF file try to show, the Internet Download Manager download it and abort the preview .. after search I found that using object instead of iframe may solve the problem, but it didn't work the pdf viewer appeared white, what can I do to prevent auto download ? or using another way (Plugin) to show PDF file content.

<iframe 

  class=pdf 

  webkitallowfullscreen= 

  mozallowfullscreen= 

  allowfullscreen= 

  frameborder=no 

  width='.$width.' 

  height='.$height.' 

  src='.$baseurl.'/assets/pdf/web/viewer.html?file='.urlencode($pdf_url).' 

  data-src='.$pdf_url.'>

  '.$pdf_url.'

</iframe>

This is not something related to developing issue , this is something related to user specific environement.

The Issue :

Using IDM ,any URL that ends with a media extension (e.g *.JPG , *.PNG , *.MP4 , *.WMV , *.PDF ..etc ) will be downloaded automatically , However on the other hand if the user doesnt have IDM installed , the file will be viewed immediately in browser window.

Possible Solutions :

Remove PDF extension Handler from IDM , to prevent auto download, and i think the image explains it very well.

IDM

Modify response header for your PDF link to force your browser to view pdf inside its view , please consider that each browser may handle the response differently , more details about this method can be found here.

Final Note:

As a developer you shouldnt handle each user specific environment , we
suppose that when user installs a specific app to handle generic files
, then it is his/her role to handle that application , and not the
developer role , cause if you follow this algorithm you jump inside
infinite loop handling different users specific setup.
