Funciona en IE pero no en Mozilla.

[userman]

Hola,

alguien me podria decir porque me falla el siguiente javascript en el navegador Mozilla?? en Internet Explorer y Google Chrome me funciona bien.

Código:

var ie45,ns6,ns4,dom;
if (navigator.appName=="Microsoft Internet Explorer") ie45=parseInt(navigator.appVersion)>=4;
else if (navigator.appName=="Netscape"){  ns6=parseInt(navigator.appVersion)>=5;  ns4=parseInt(navigator.appVersion)<5;}
dom=ie45 || ns6;

var http=createRequestObject();
var objectId = '';
var loadok = 0;

function createRequestObject(htmlObjectId){
    var obj;
    var browser = navigator.appName;
    
    if(browser == "Microsoft Internet Explorer"){
        obj = new ActiveXObject("Microsoft.XMLHTTP");
    }
    else{
        obj = new XMLHttpRequest();
    }
    return obj;    
}

function sendReq(serverFileName, variableNames, variableValues,objId) {
	var paramString = '';
	
	objectId = objId;
	
	variableNames = variableNames.split(',');
	variableValues = variableValues.split(',');
	
	for(i=0; i<variableNames.length; i++) {
		paramString += variableNames[i]+'='+variableValues[i]+'&';
	}
	paramString = paramString.substring(0, (paramString.length-1));
			
	if (paramString.length == 0) {
	   	http.open('get', serverFileName);
	}
	else {
		http.open('get', serverFileName+'?'+paramString);
	}
    http.onreadystatechange = handleResponse;
    http.send(null);
}

function handleResponse() {
	
	if (http.readyState == 4) {
		responseText = http.responseText;
		getobj(objectId).innerHTML = responseText;
    } else {
		getobj(objectId).innerHTML = "<br><div align=center><img src='images/loading.gif' border=0><br>Loading content ...</div>";
	}
