[jQuery] Posting form when pressing enter.

Hello

$(function(){
$('input').keydown(function(e){
if (e.keyCode == 13) {
$(this).parents('form').submit();
return false;
}
});
});

This script handles it very well, but it has some problems. Specially
with browsers autocomplete. When i use this script and start typing in
a value into form, then it offers complete word. When i press key down
to choose it and press enter to select it, the form gets posted empty.
Which blows.

Is there a simple workaround to adapt with autocomplete or do i have
to start counting enters - if up or down key has been pressed then 1st
enter does nothing and 2nd posts the form?

Alan.
