Developing a perpetually scrolling container within a webpage

I am attempting to implement a scrollable div on my webpage that can continuously load content. I am currently using the following code snippet for this -->

http://jsfiddle.net/cyrus2013/Qq85d/

$(document).ready(function(){

function loadMoreContent()
{
    $('div#lastPostsLoader').html('<img src="../bigLoader.gif">');

    $.get("loadmore.php", function(data){
        if (data != "") {
            //console.log('add data..');
            $(".items").append(data);
        }
        $('div#lastPostsLoader').empty();
    });
};

//loadMoreContent(); $(window).scroll(function(){

  var wintop = $(window).scrollTop(), docheight = $(document).height(), winheight = $(window).height();
  var  scrolltrigger = 0.95;

  if  ((wintop/(docheight-winheight)) > scrolltrigger) {
     //console.log('scroll bottom');
     loadMoreContent();
  }

}); });

However, the code provided is meant for implementing this functionality across the entire page, while I specifically need it for a particular 'div' within the webpage.

In this section of the webpage, I am facing challenges in determining the dimensions of the 'div'.

var wintop = $(window).scrollTop(), docheight = $(document).height(), winheight = $(window).height();
      var  scrolltrigger = 0.95;

An example of what I am trying to achieve is similar to the "Ticker" feature on Facebook, where updates are displayed in real-time on the right side of the screen.

I would appreciate any help in figuring out the necessary code for this requirement. Thank you in advance!

What do you think of this code snippet (the randomPara content is just for simulation purposes)?

See Demo

var scroller;
var initContents = 10;
var shown = 0;
var content = [];

function initialize(){
 var scroller = document.getElementById('scroller');
 for(var i=0;i<100;i++){
  var randomPara = "";
  var words = Math.floor(Math.random()*100);
  for(var j=0;j<words;j++) randomPara += "word ";
  content.push(randomPara+"<br>");
 }
 for(var i=0;i<initContents;i++){
  scroller.innerHTML += content[shown];
  shown++;
 }
 scroller.onscroll = function(){
  if(shown < content.length) {
    if(this.scrollTop >= this.scrollHeight-this.clientHeight) {
      scroller.innerHTML += content[shown];
      shown++;
    }
  }
 }
}
