I am make a simple demo where I am showing only two divs.When user scroll up it create a div and prepend to exiting div.when user scroll again it again create a div , and remove the last div (because i want to show on two div).But I am struck my i come down bottom of the div I want to append the divs which i remove .

I take example when I load "page_5" then scroll up "page_4" load , again "page_3" load and remove "page_5" .Now if I want to come down I want to remove "page_3" and load "page_5" with page_4 already load.

can we do that functionality ? here I am trying but not getting success ..

var pages = [page_1, page_2, page_3, page_4, page_5];
var backupPages=new Array();
var totalPage = "page_" + pages.length;
$("<div id='" + totalPage + "'>" + pages.pop() + "</div>").prependTo($("#fullContainer"));


    $("#fullContainer").scroll(function () {
        // top
        if ($(this).scrollTop() === 0 && pages.length) {
            console.log("up");
            var stringLoad = "page_" + pages.length;
            $("<div id='" + stringLoad + "'>" + pages.pop() + "</div>").prependTo($("#fullContainer"));

            //remove element at 2nd index
            $('#fullContainer').children().slice(2).remove()
        }
        if ($(this).scrollTop() >= $(this)[0].scrollHeight - document.body.offsetHeight) {
            console.log("down"+$('#fullContainer div:last-child').attr('id'));
        }
    });

This kind of design looks highly questionable to me, especially the attempt to do it fully on the client side. Where are you getting new data to append? I doubt the whole idea makes sense.
