I will like the js below to be able to display a loading,  indication to alert the user that the page is loading. As I'm not an expert in this field, can you please modify it to function like that. It will be cool if the loading indicator can include a gif animator with filename loading.gif.

I'll deeply appreciate your help. The code of the .js file follows;

var bustcachevar=1 //bust potential caching of external pages after initial request? (1=yes, 0=no)
var loadedobjects=""
var rootdomain="http://"+window.location.hostname
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
}
}
}
