How can i display a Blob with pdf content immediately a new tab or have it displayed inline using an iframe?

in chrome and FF i can use something like this

var url = URL.createObjectURL(blob);
$('#uplFrame').attr('src', url);

but does not work in IE...i read online that IE is using the following for handeling blobs

window.navigator.msSaveOrOpenBlob(blob, "filename");

however this will ask the user if he wants to save or open the file in a new window. is it possible to let the code open the blob this automatically?

or is there a similar solution for the "createObjectURL" that does work for IE?

• 2 I think you'd need to create a temp file on the server to open it in a new window or tab using the browser. To serve a new document your server needs a file to server from, but if you can temporarily cache it on your server you can open the pdf directly in the browser no problem. – DrewT Commented Aug 20, 2015 at 16:33
• 1 According to MDN, URL.createObjectURL(blob) is supported in IE10 and up, but OP doesn't mention IE version. – EternalHour Commented Sep 26, 2019 at 20:45

For security reason and implementation the operation is not allowed in IE so the team build a specific API for asking permissions:

  // Save the blob1 content to a file, giving just a "Save" option
  window.navigator.msSaveBlob(blob1, 'msSaveBlob_testFile.txt'); 

  // Save the blob2 content to a file, giving both "Save" *and* "Open" options
  window.navigator.msSaveOrOpenBlob(blob2, 'msSaveBlobOrOpenBlob_testFile.txt');
