[Javascript] firing submit event

I think you're on the right track.

Make a delay that is triggered onkeyup, and it fires the submit if the value
in the field is the same as when triggered.

onkeyup="setTimeOut('if (\''+this.value+'\' ==
document.formname.elementname.value) document.formname.submit();', 500);"

This will be triggered for every "keystroke" but will only submit if no
additional keystrokes happen for half a second (500 milliseconds). You may
need to adjust this delay, based on your bar readers.

If the barcode is always the same number of digits, say 23, then you can do
this instead:

onkeyup="if (this.value.length == 23) document.formname.submit();"
