Is this from a web browser or using a local javascript interpreter like rhino? If it's from a web browser, you need to edit your question and say which one, since the mechanisms to allow local file access depend on the browser. Or if your web browser is running locally you should mention that too.ninjagecko– ninjagecko2011-07-16 07:05:43 +00:00Commented Jul 16, 2011 at 7:05

Use the File API.
With Blob data, you can get a Uint8Array or whatever other typed array you like. Here's a link to more info about Uint8Arrays.

I've been messing with binary data lately in JavaScript. Just happened to know a few good resources.
You need to create handler that will do the job the javascript will only call the handler with the right parameters according to what you need look at jquery ajax call: http://api.jquery.com/jQuery.ajax/
