If anyone still looks for that, here is what I'm doing (and working): var pdfAsDataUri = "data:application/pdf;base64,"+byteArray;. var pdfAsDataUri = "data:application/pdf;base64,"+byteArray; nvrehs.info( pdfAsDataUri);. Data URI's don't work on all browsers. Especially even recent. Hi all I have the following ajax call from a webpage. The url points to a webservice (C#) which returns a PDF file as a byte array. How do I.

Firefox-specific examples Receiving binary data using JavaScript typed arrays The responseType property of the XMLHttpRequest object can be set to change the expected response type from the server. Possible values are the empty string default , "arraybuffer", "blob", "document", "json", and "text". This is null if the request is not complete or was not successful. This example reads an image as a binary file and creates an 8-bit unsigned integer array from the raw bytes. Note that this will not decode the image and read the pixels. You will need a png decoding library for that. This tells the browser not to parse it, and to let the bytes pass through unprocessed. The valid range for x is from 0 to filestream.

Perhaps I could search for when c2was generated or its decimal representation, and trace through the logic that produced it. In fact, the number never even occurred in the list of numbers generated by jsmidgen.

It was ultimately a dead end search. I still had no idea why the data was being corrupted, but I did learn that jsmidgen creates a list of bytes just as a regular array of numbers and then calls String. So if I wanted to see the raw bytes, all I had to do was convert each character in this string back into the character code that generated it.

An Introduction To JavaScript Blobs and File Interface

I could see that the same sequence of bytes I got in the browser was exactly the same as the one in Node! This was it! I had the correct output — it was just trapped within my application. Any attempt to send it to the outside world as a file resulted in this strange corrupted mess.

I felt like the truth was in my grasp, but I was powerless to do anything about it. It was as if I was at a crime scene and knew who the killer was, and was yelling the answer at the top of my lungs but no one could hear me.

Could the mere act of converting these bytes to a JavaScript string change them? In principle it was possible if the numbers I was storing were outside of the range that strings could hold, and they were being truncated or overflowing somehow. I verified this by ensuring that all values in the byte array generated by jsmidgen were below , so they definitely each fit in one byte, and nothing could possibly overflow.

If JavaScript strings stored 2 bytes for each character, why was I only seeing 1 byte per value in the resulting file? There should be empty 0 bytes next to each value. Could I force it to write out the original 2 bytes per value?
