Как сделать бесконечную подгрузку новостей на главной и в fullstory на DLE 15.1?

$(document).ready(function(){
    var loadLink = $('#nav-load'), loadStatus = 0;
    $(window).scroll (function () {     
    if ($(this).scrollTop() + $(this).height() + 300 > loadLink.offset().top) {
        var urlNext = loadLink.find('a').attr('href');
            if (urlNext !== undefined && loadStatus == 0) {
                loadStatus = 1;
                $.ajax({
                    url: urlNext,
                    beforeSend: function() {
                        //ShowLoadin();
                    },            
                    success: function(data) {
                        $('#bottom-nav').remove();
                        $('.sect-content').append($('.sect-content', data).html()).after($('#bottom-nav'));
                        //HideLoadin();
                        loadStatus = 0, loadLink = $('#nav-load');
                    }  
                });
            } else {
                loadLink.remove();
            };
        };
    });  
});

<div class="sect-content">
      {content}
</div>
