Question

Is it possible that the opera browser ignore the keyCode 40 (arrow down)?

 $('#test').keyup(function(e) {
        $('body').append('' + e.keyCode + '');
 })

Test it at: http://www.jsfiddle.net/V9Euk/454/

Thanks in advance!

Answer 1

Try to use the autocomplete attribute, and set it to off:

<input id="test" value="" autocomplete="off" >

Opera uses the arrow down key for auto completion, and may therefore suppress the forwarding of the event.
