ragazzi, salve
come č possibile ke offline su IE la funzione di richiamo dell'XMLHTTP funzia OK, mentre online nč su firefox nč su IE da risultato?

questo č il codice

codice:
var timeLoading;
var textStatus;
var arrayComponent=["MSXML2.XMLHTTP.5.0","MSXML2.XMLHTTP.4.0","MSXML2.XMLHTTP.3.0","MSXML2.XMLHTTP","MICROSOFT.XMLHTTP.1.0","MICROSOFT.XMLHTTP.1","MICROSOFT.XMLHTTP"];
function selectObj () {
	var varObjNew=null;
	for(var cc=0;cc<arrayComponent.length;cc++){
		try {varObjNew=new ActiveXObject(arrayComponent[cc]);break;}catch(c){varObjNew=null;}
		
	}
	if(typeof XMLHttpRequest!="undefined" || !varObjNew){
		try{varObjNew=new XMLHttpRequest();}catch(e){alert("Impossibile create una connessione HTTP! Nessun componente XML installato! ("+e.message+")");}
	}
	return varObjNew;
}
function openXML(funcToCall,url,obj,typeResponse,typeSend,postValue) {
	if(typeof typeSend=="undefined" || typeSend.length<=0){typeSend="GET"}
	typeSend=typeSend.toUpperCase();
	obj.open(typeSend,url,true);
	timeLoadingtemp=(new Date()).getTime();
	if(typeSend=="POST"){obj.setRequestHeader("Content-Type","application/x-www-form-urlencoded");}
	obj.onreadystatechange=function(){
		if(obj.readyState==4){
			if (obj.status==200){
				var txtR='txt';if(typeResponse=="xml"){txtR=obj.responseXML}else{txtR=obj.responseText};
				timeLoading=((new Date()).getTime())-timeLoadingtemp;timeLoading=timeLoading/1000;timeLoading=timeLoading.toString()+" sec.";
				textStatus="Data Loaded";
				funcToCall(txtR);
			}else{
				alert("Status Error n."+obj.status);
			}
		}
	};
	if(typeSend=="POST"){obj.send(postValue);}else{obj.send();}
}

// INIZIO CODICE MODIFICABILE
function provaa(value){
	document.write("loaded in"+timeLoading+"
"+value);
}
