javascript/AJAX file uploading

I need to upload a local file to server with javascript/AJAX. The problem is how can I select a file and read it into byte array?

PS: I can't use HTML form to do the file uploading.

With HTML5, there is the FileReader API. It allows you to read the files that your users have selected. The other day I build a CSV parser using HTML5 and JS only. It wasn't hard at all either.

Since it is a newer api, it isn't well supported. Check out the support here. http://caniuse.com/#search=filereader

If you don't want to do that, then you will need to do the flash solution that Benjamin has suggested.

If you more info, go here. Pretty awesome!!! https://developer.mozilla.org/en/DOM/FileReader

You either use a Iframe with a HTML form or flash (theres no way to convert a file to a byte array using javascript)

Please note that flash will not work on ipad, iphone and all other mobile apple
