if the scanner inputs its data into a textarea or something ....
<form id="frm"><input type="text" id="barcode" value="scanner-input" /
></form>
intercept form-submit, usually triggered by enter on an text-input
$('#frm').submit(function(e) {
alert( 'barcode: ' + $('#barcode').text() );
return false; // stop form-submit
});
or intercept the ENTER-key with the keydown/keyup event and check the
passed event-argument ...
$(document.body).keydown(function(e) {
alert('key-code: ' + e.which);
});
