Opening PDF String in new window with javascript

Question

Hello,

I have a formatted PDF string that looks like

%PDF-1.73 0 obj<<< /Type /Group /S /Transparency /CS /DeviceRGB >> /Resources 2 0 R/Contents 4 0 R>> endobj4 0 obj<> streamx��R=o�0��+��=|vL�R���l�-��ځ,���Ge�JK����{���Y5�����Z˯k�vf�a��`G֢ۢ��Asf�z�ͼ��`%��aI#�!;�t���GD?!���<�����B�b��

...

00000 n 0000000703 00000 n 0000000820 00000 n 0000000926 00000 n 0000001206 00000 n 0000001649 00000 n trailer << /Size 11 /Root 10 0 R /Info 9 0 R >>startxref2015%%EOF

I am trying to open up this string in a new window as a PDF file. Whenever I use window.open() and write the string to the new tab it thinks that the text should be the contents of an HTML document. I want it to recognize that this is a PDF file.

Any help is much appreciated

You might want to explore using the data URI. It would look something like.

window.open("data:application/pdf," + escape(pdfString));

I wasn't immediately able to get this to work, possible because formating of the binary string provided. I also usually use base64 encoded data when using the data URI. If you are able to pass the content from the backend encoded you can use..

window.open("data:application/pdf;base64, " + base64EncodedPDF);

Hopefully this is the right direction for what you need. Also note this will not work at all in IE6/7 because they do not support Data URIs.
