Вот несколько способов:
Masonry Infinite Scroll http://desandro.com/demo/masonry/docs/infinite-scroll.html
Cpde Образец:
$wall.infinitescroll({
navSelector : '#page_nav', // selector for the paged navigation
nextSelector : '#page_nav a', // selector for the NEXT link (to page 2)
itemSelector : '.box', // selector for all items you'll retrieve
loadingImg : 'img/loader.gif',
donetext : 'No more pages to load.',
debug: false,
errorCallback: function() {
// fade out the error message after 2 seconds
$('#infscr-loading').animate({opacity: .8},2000).fadeOut('normal');
}
},
// call masonry as a callback
function( newElements ) {
$(this).masonry({ appendedContent: $( newElements ) });
}
);
AJAXianWay (без плагина) http://ajaxian.com/archives/implementing-infinite-scrolling-with-jquery
Код:
//Scroll Detection
$(window).scroll(function(){
if ($(window).scrollTop() == $(document).height() - $(window).height()){
lastPostFunc();
}
});
//Loading More content
function lastPostFunc()
{
$(’div#lastPostsLoader’).html(’<img src="bigLoader.gif"/>’);
$.post("scroll.asp?action=getLastPosts&lastID=" + $(".wrdLatest:last").attr("id"),
function(data){
if (data != "") {
$(".wrdLatest:last").after(data);
}
$(’div#lastPostsLoader’).empty();
});
};
Бесконечный свиток Плагин jQuery (изначально плагин WordPress) http://www.infinite -scroll.com/infinite-scroll-jquery-plugin/
Пример кода:
// infinitescroll() is called on the element that surrounds
// the items you will be loading more of
$('#content').infinitescroll({
navSelector : "div.navigation",
// selector for the paged navigation (it will be hidden)
nextSelector : "div.navigation a:first",
// selector for the NEXT link (to page 2)
itemSelector : "#content div.post"
// selector for all items you'll retrieve
});
All options
// usage:
// $(elem).infinitescroll(options,[callback]);
// infinitescroll() is called on the element that surrounds
// the items you will be loading more of
$('#content').infinitescroll({
navSelector : "div.navigation",
// selector for the paged navigation (it will be hidden)
nextSelector : "div.navigation a:first",
// selector for the NEXT link (to page 2)
itemSelector : "#content div.post",
// selector for all items you'll retrieve
debug : true,
// enable debug messaging ( to console.log )
loadingImg : "/img/loading.gif",
// loading image.
// default: "http://www.infinite-scroll.com/loading.gif"
loadingText : "Loading new posts...",
// text accompanying loading image
// default: "<em>Loading the next set of posts...</em>"
animate : true,
// boolean, if the page will do an animated scroll when new content loads
// default: false
extraScrollPx: 50,
// number of additonal pixels that the page will scroll
// (in addition to the height of the loading div)
// animate must be true for this to matter
// default: 150
donetext : "I think we've hit the end, Jim" ,
// text displayed when all items have been retrieved
// default: "<em>Congratulations, you've reached the end of the internet.</em>"
bufferPx : 40,
// increase this number if you want infscroll to fire quicker
// (a high number means a user will not see the loading message)
// new in 1.2
// default: 40
errorCallback: function(){},
// called when a requested page 404's or when there is no more content
// new in 1.2
localMode : true
// enable an overflow:auto box to have the same functionality
// demo: http://paulirish.com/demo/infscr
// instead of watching the entire window scrolling the element this plugin
// was called on will be watched
// new in 1.2
// default: false
},function(arrayOfNewElems){
// optional callback when new content is successfully loaded in.
// keyword `this` will refer to the new DOM content that was just added.
// as of 1.5, `this` matches the element you called the plugin on (e.g. #content)
// all the new elements that were found are passed in as an array
});
// load all post divs from page 2 into an off-DOM div
$('<div/>').load('/page/2/ #content div.post',function(){
$(this).appendTo('#content'); // once they're loaded, append them to our content area
});
