iframe pdf viewer problem at IE browser

[onur_sara]

Hi All ,

I am getting PDF data from backend system and showing it in iframe pdf viewer  with codes below . This solution works well at Chrome or Firefox .

var srcURL = "data:application/pdf;base64," +data;
          oHTML.setContent( "<iframe src='"+srcURL+"'  frameborder='0' style='position: absolute; height:100%; border: none' height='100%' width='100%''></iframe>");

But if I run the application at IE browser , it is showing an empty frame .

If you have any idea about it , please let me know .

Thanks .

Hi Onur,

When reviewing the browser developer tools in IE, do you see if the PDF data is loaded correctly?

in you gateway implementation, did you add the HTTP response header content-disposition?

data: ls_header type ihttpnvp.

ls_header-name = 'content-disposition'.

ls_header-value = 'inline;filename=file.pdf'.

set_header( ls_header ).

Best regards,

Maarten

Hi ,

PDF data is loading correctly . But  I didn't add  content dispotion on my response  header .

I found something that  " Internet Explorer does not support the use of DATA URIs as the source of IFRAMEs "

at below website .

internet explorer - Workaround of showing a base64 pdf on IE9+ - Stack Overflow

So I need to give a pdf url into iframe tag .

Does Content dispotion solve my problem ? and Can you give me an example how I can  use it in my JS code at Client side   ?

Thanks .

Hi Onur,

Hmm, I wasn't aware of that... Like the link states, it could be a good workaround to open the URL to get the pdf in a new tab/window.

window.open("https://server_hostname/path/to/gw/service/pdfEntity/$value")

As I said, I'm not sure the content-disposition will solve the issue you are currently having (I suppose not when reading the link you have provided). Anyway, the content-disposition http header does not have to be handled by the UI. Basically you are telling the browser to show the pdf inline (and not as a download). This is handled automatically by the browser.

Good luck!

Best regards,

Maarten
