COuntdown

[galaxia_one]

Purtroppo in javascript sono negato...
qualcuno può passarmi, fare, uno script in javascript a cui io passo i valori %y, %mo,...
e poi fare un coundown autoaggiornante...
Sto sclerando a cercare su internet...non trovo niente...Vi prego

function countdiff($y, $mo, $d, $h, $m, $s){ 
                $cdate = mktime($h, $m, $s, $mo, $d, $y, -1); 
                $today = time(); 
                $difference = $cdate - $today; 
             
           
                $dleft = floor($difference/60/60/24); 
                $hleft = floor(($difference - $dleft*60*60*24)/60/60); 
                $mleft = floor(($difference - $dleft*60*60*24 - $hleft*60*60)/60); 
                $sleft = floor(($difference - $dleft*60*60*24 - $hleft*60*60 - $mleft*60)); 
                $countdowndate =  date("l j F Y, G:i:s",$cdate); 
                $currenttime = date("j F Y, G:i:s",$today); 
                 


                    if($dleft==0 && $hleft!=0 && $mleft!=0 && $sleft!=0) 
                        { 
                            echo 'Mancano '.$hleft.' h, '.$mleft.' min e '.$sleft.' sec

'; 
                        } 
                    else if($dleft==0 && $hleft==0 && $mleft!=0 && $sleft!=0) 
                        { 
                            echo 'Mancano '.$mleft.' min e '.$sleft.' sec

'; 
                        } 
                    else if($dleft==0 && $hleft==0 && $mleft==0 && $sleft!=0) 
                        { 
                            echo 'Mancano '.$sleft.' sec

'; 
                        } 
                    else 
                        { 
                            echo 'Mancano '.$dleft.' gg, '.$hleft.' h, '.$mleft.' min e '.$sleft.' sec

'; 
                        } 
             
                } 
        }
