Aiuto codice js per effetto scritta scorrevole

**YOGHI87** · 18-12-2008, 17:29

Salve, mi sapreste aiutare? io ho un codice javascript e non me ne intento, l'ho solo trovato in rete e lo volevo usare per il mio sito creato con joomla, però mi guardate se c'è qualche errore nel codice? Dovrebbe dare una scritta che scorre effetto film...

codice:

<HTML>
 <HEAD>
   <TITLE> INCONTRO </TITLE>
 </HEAD>
<BODY>
<script language="JavaScript1.2">
//Specify the marquee's width (in pixels)
var marqueewidth=330
//Specify the marquee's height
var marqueeheight=150
//Specify the marquee's scroll speed (larger is faster)
var speed=1
//Specify the marquee contents
var marqueecontents='<center><center><font face="Comic Sans MS">[b]SABATO 20 NOVEMBRE TORRE CONTRO PIOBBICO 90'

if (document.all){
document.write('<marquee direction="up" scrollAmount='+speed+' style="width:'+marqueewidth+';height:'+marqueeheight+'">'+marqueecontents+'</marquee>')}
else if(document.layers){
document.write('<ilayer id="cmarquee01" width="'+marqueewidth+'" height="'+marqueeheight+'"><layer id="cmarquee02" width="'+marqueewidth+'" height="'+marqueeheight+'"></layer></ilayer>')}

function regenerate(){
window.location.reload()
}
function regenerate2(){
if (document.layers){
setTimeout("window.onresize=regenerate",450)
intializemarquee()
}
}

function intializemarquee(){
document.cmarquee01.document.cmarquee02.document.write(marqueecontents)
document.cmarquee01.document.cmarquee02.document.close()
thelength=document.cmarquee01.document.cmarquee02.document.height
scrollit()
}

function scrollit(){
if (document.cmarquee01.document.cmarquee02.top>=thelength*(-1)){
document.cmarquee01.document.cmarquee02.top-=speed
setTimeout("scrollit()",100)
}
else{
document.cmarquee01.document.cmarquee02.top=marqueeheight
scrollit()
}
}

window.onload=regenerate2
// --> 
</script>
</BODY>
</HTML>

codice:
