实例代码：

$(function(){
                $('#content').scrollPagination({
                    'contentPage': 'democontent.html', // the url you are fetching the results
                    'contentData': {}, // these are the variables you can pass to the request, for example: children().size() to know which page you are
                    'scrollTarget': $(window), // who gonna scroll? in this example, the full window
                    'heightOffset': 10, // it gonna request when scroll is 10 pixels before the page ends
                    'beforeLoad': function(){ // before load function, you can display a preloader div
                        $('#loading').fadeIn();
                    },
                    'afterLoad': function(elementsLoaded){ // after loading content, you can use this function to animate your new elements
                         $('#loading').fadeOut();
                         var i = 0;
                         $(elementsLoaded).fadeInWithDelay();
                         if ($('#content').children().size() > 100){ // if more than 100 results already loaded, then stop pagination (only for testing)
                            $('#nomoreresults').fadeIn();
                            $('#content').stopScrollPagination();
                         }
                    }
                });

// code for fade in element by element
                $.fn.fadeInWithDelay = function(){
                    var delay = 0;
                    return this.each(function(){
                        $(this).delay(delay).animate({opacity:1}, 200);
                        delay += 100;
                    });
                };
                       
            });
