Perhaps:

<html>
<head>
<title>keypress .htm</title>
<script type="text/javascript">
function eleven(that) {
if (that.value.len gth == 11) {
document.form1. submit();
}
}
</script>
</head>
<body>
<form action="keypres s.htm" method="get" name="form1">
<input type="text" onkeypress="ele ven(this)">
</form>
</body>
</html>

if i set it to 10 characters, person has to enter 10 chars, the form is
being submitted, but only 9 characters are submitted. It cuts the last
character.

any ideas?

us the onkeyup or onchange of the field instead of the onkeypress. onkeypress
fires as soon as the key is pressed, not after its released. And it may be a
timing issue where the key is pressed, and before its released the form is
submitted.

Personally, I would use the onchange event and when the field gets changed, and
exited, the form would submit.

on change does not work at all
onkeypress, onkeydown, onkeyup - those are cutting the last character.

any other ideas? :)

"actually when i set
if (that.value.len gth == 3) {

it submits 3 characters, but i have to enter 4 to submit that form., nothing
happens after entering 3rd char.
after 4th form is submitted but i have only 3 chars submitted..

Sorry, if you suggest that the read data should be submitted
immediately without user control, you have no clue of how
barcode readers (can) (mal)function. Let it be a bug (real
or electronical) on the barcode and your whole data is garbled.

I strongly recommend against such an automatism.
