Frame helyettesítése divben, FF alatt megy, IE, Crome alatt nem. Mi lehet a gond?

Sziasztok

Ezzel a scripttel van gondom, ugyanis a Firefox, és a Safari normálisan kezeli, viszont az IE, és a Chrome nem kezeli normálisan. A kód a dynamicdrive oldalról származik, de az AJAX-hoz még nemigazán értek, így nem tudom hogy hol lehet a hiba. A script:

<script type="text/javascript">

/***********************************************

var bustcachevar=1 //bust potential caching of external pages after initial request? (1=yes, 0=no)

var loadedobjects=""

var rootdomain=" [link]

var bustcacheparameter=""

function ajaxpage(url, containerid){

var page_request = false

if (window.XMLHttpRequest) // if Mozilla, Safari etc

page_request = new XMLHttpRequest()

else if (window.ActiveXObject){ // if IE

try {

page_request = new ActiveXObject("Msxml2.XMLHTTP")

}

catch (e){

try{

page_request = new ActiveXObject("Microsoft.XMLHTTP")

}

catch (e){}

}

}

else

return false

page_request.onreadystatechange=function(){

loadpage(page_request, containerid)

}

if (bustcachevar) //if bust caching of external page

bustcacheparameter=(url.indexOf("?")!=-1)? "&"+new Date().getTime() : "?"+new Date().getTime()

page_request.open('GET', url+bustcacheparameter, true)

page_request.send(null)

}

function loadpage(page_request, containerid){

if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))

document.getElementById(containerid).innerHTML=page_request.responseText

}

function loadobjs(){

if (!document.getElementById)

return

for (i=0; i<arguments.length; i++){

var file=arguments[i]

var fileref=""

if (loadedobjects.indexOf(file)==-1){ //Check to see if this object has not already been added to page before proceeding

if (file.indexOf(".js")!=-1){ //If object is a js file

fileref=document.createElement('script')

fileref.setAttribute("type","text/javascript");

fileref.setAttribute("src", file);

}

else if (file.indexOf(".css")!=-1){ //If object is a css file

fileref=document.createElement("link")

fileref.setAttribute("rel", "stylesheet");

fileref.setAttribute("type", "text/css");

fileref.setAttribute("href", file);

}

}

if (fileref!=""){

document.getElementsByTagName("head").item(0).appendChild(fileref)

loadedobjects+=file+" " //Remember this object as being already added to page

}

}

}

</script>
