Copia testo da textarea

[kicko]

salve a tutti ragazzi...
su http://www.dynamicdrive.com ho trovato un codice per copiare i dati contenuti in una textarea al click su un link ...
l'indirizzo a cui si trova lo script è questo http://www.dynamicdrive.com/dynamici...selectform.htm

il mio problema è che quello script nn funziona con firefox 2

qualcuno saprebbe dirmi come variare il codice per farlo funzionare anche sul mio browser ?

style>
.highlighttext{
background-color:yellow;
font-weight:bold;
}
</style>

<script language="Javascript">
<!--

*/

//specify whether contents should be auto copied to clipboard (memory)
//Applies only to IE 4+
//0=no, 1=yes
var copytoclip=1

function HighlightAll(theField) {
var tempval=eval("document."+theField)
tempval.focus()
tempval.select()
if (document.all&&copytoclip==1){
therange=tempval.createTextRange()
therange.execCommand("Copy")
window.status="Contents highlighted and copied to clipboard!"
setTimeout("window.status=''",1800)
}
}
//-->
</script>
 


----


<form name="test">
Select All

<textarea name="select1" rows=10 cols=35 >This is some text. This is some text. This is some text. This is some text.</textarea>
</form>

per comodità ho riportato il codice anche qua...

grazie in anticipo

umh, no, nn ho capito niente

nn sono esperto di javascript (a dire il vero nn c'è niente in cui sia esperto nel campo della programmazione) cmq,
ho provato a inserire la funzione da te segnalata all'interno del mio script e richiamarla, ma senza risultato

ecco il codice che ho provato ..

<script language="Javascript">

//specify whether contents should be auto copied to clipboard (memory)

//0=no, 1=yes
var copytoclip=1

function HighlightAll(theField) {
var tempval=eval("document."+theField)
tempval.focus()
tempval.select()
if (document.all&&copytoclip==1){
therange=tempval.createTextRange()
therange=copy_clip(therange)
//therange.execCommand("Copy")  -- -riga tolta dal codice...ad intuito :D
window.status="Contents highlighted and copied to clipboard!"
setTimeout("window.status=''",1800)
}
}

function copy_clip(meintext)
{
 if (window.clipboardData) 
   {
   
   // the IE-manier
   window.clipboardData.setData("Text", meintext);
   
   // waarschijnlijk niet de beste manier om Moz/NS te detecteren;
   // het is mij echter onbekend vanaf welke versie dit precies werkt:
   }
   else if (window.netscape) 
   { 
   
   // dit is belangrijk maar staat nergens duidelijk vermeld:

   netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');
   
   // maak een interface naar het clipboard
   var clip = Components.classes['@mozilla.org/widget/clipboard;1']
                 .createInstance(Components.interfaces.nsIClipboard);
   if (!clip) return;
   
   // maak een transferable
   var trans = Components.classes['@mozilla.org/widget/transferable;1']
                  .createInstance(Components.interfaces.nsITransferable);
   if (!trans) return;
   
   // specificeer wat voor soort data we op willen halen; text in dit geval
   trans.addDataFlavor('text/unicode');
   
   // om de data uit de transferable te halen hebben we 2 nieuwe objecten 
   // nodig om het in op te slaan
   var str = new Object();
   var len = new Object();
   
   var str = Components.classes["@mozilla.org/supports-string;1"]
                .createInstance(Components.interfaces.nsISupportsString);
   
   var copytext=meintext;
   
   str.data=copytext;
   
   trans.setTransferData("text/unicode",str,copytext.length*2);
   
   var clipid=Components.interfaces.nsIClipboard;
   
   if (!clip) return false;
   
   clip.setData(trans,null,clipid.kGlobalClipboard);
   
   }
   alert("Following info was copied to your clipboard:\n\n" + meintext);
   return false;
}
//-->
</script>

un esempio funzionante per usare questa funzione ?

thx..
