Usually we look for page height and scroll height, to see if we need

Have you heard about the jQuery Waypoint plugin.

Below is the simple way of calling a waypoints plugin and having the page load more Content once you reaches the bottom on scroll :

$(document).ready(function() {
    var $loading = $("
Loading more items…
"),
    $footer = $('footer'),
    opts = {
        offset: '100%'
    };

    $footer.waypoint(function(event, direction) {
        $footer.waypoint('remove');
        $('body').append($loading);
        $.get($('.more a').attr('href'), function(data) {
            var $data = $(data);
            $('#container').append($data.find('.article'));
            $loading.detach();
            $('.more').replaceWith($data.find('.more'));
            $footer.waypoint(opts);
        });
    }, opts);
});
