Utilizing Ajax to fetch a div element from a web page

Hey there! I have a link set up that loads a page into a specific div ID, which is #ey_4col3.

The issue I'm facing is that it loads the entire page along with all its contents, but what I really want to load from that page is just the content within the ID: #page-contents

I've included the Ajax and JavaScript code below. I think I might not be using the correct method for achieving this, and I'm open to any suggestions on how to manipulate what I have or if there's a cleaner, simpler way to accomplish this task. Any help would be greatly appreciated:

var loadedobjects=""
var rootdomain="http://"+window.location.hostname

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)
    }

    page_request.open('GET', url, 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
        }
    }
}

Thank you in advance!

Utilize the jQuery .load() function to load specific page fragments. Update your function like this:

function loadPage(url, containerID) {
    $('#' + containerID).load(url + ' #page-contents');
}

The $('#' + containerID) creates a jQuery object linked to the DOM element with an id matching the value of containerID. Then, .load(url + ' #page-contents') instructs jQuery to make an AJAX request to url and then set the HTML content of the #page-contents element in the returned HTML as the content for the selected element.
