<p>How I can detect inserted value to text field immediately after inserting? <code>change</code> event rises only after focus lost, <code>keyPress, keyUp, keyDown</code>, etc can't help me, because new values are inserted from barcode scanner(it don't rises this keyboard events). Only using Timer and periodically check values in text field? </p>
