No you can't and you don't want to, it would be a security flaw.
Javascript just can't read files on your computer otherwise any website
could get all your personal data.

I’d bet money that they use a hidden iframe. Gmail already uses that
to avoid breaking the back button, from what I’ve read. It’s
impossible to send multipart form data through XMLHttpRequest, or so
everything I read says and my own personal attempts confirm. There is
an IE ActiveX plugin that will let you send files in a similar
fashion, but it’s IE only. I forget the name of it at this moment.

I’ve not looked into how it’s done but adding an attachment in Gmail
(UK version) uploads the file without refreshing the window, and
http://www.yousendit.com <http://www.yousendit.com/> appears to send a
file via some sort of RPC or AJAX. Maybe this could be another
starting point for you.
