There is no way, in Javascript, to access the value of a file-on-disk
from the browser. You will need to trigger an actual form submission (as
you know how to do). You may wish to trigger the form submission in a
hidden iframe, and then read the response from that iframe , which would
allow your server to receive the file without a page reload.
