我正在尝试使用 this 插件为Facebook Feed创建无限滚动效果，现在我可以通过图形api（粉丝页面墙贴）访问我需要的Feed并且我将其限制为10，即便如此，Facebook还提供了实际json数据中下一个或前一个10个帖子的下一个和上一个链接，但我似乎无法使用此插件。
以下是json数据的一个例子：

我如何才能使这项功能正常运作？
非常感谢任何帮助/建议

看起来你不得不花费大量的时间与无限的scroll.js争吵，让它做你想做的事情，因为它取决于HTML中的分页链接。
根据最近的JSON响应中的下一页链接，编写自己的Javascript以检测用户何时滚动并自动加载内容可能会更容易。
如果你看一下jscroll.js的代码（一个类似于infinte-scroll的插件，但代码更简单一些），你可能会很清楚要查找什么以及何时加载新内容。具体来说，从第84行开始：
// Observe the scroll event for when to trigger the next load
function _observe() {
var $inner = $e.find('div.jscroll-inner').first(),
data = $e.data('jscroll'),
iContainerTop = parseInt($e.css('paddingTop')) + parseInt($e.css('borderTopWidth')),
iTopHeight = _isWindow ? _$scroll.scrollTop() : $e.offset().top,
innerTop = $inner.length ? $inner.offset().top : 0,
iTotalHeight = Math.ceil(iTopHeight - innerTop + _$scroll.height() + iContainerTop),
nextHref = $.trim(data.nextHref + ' ' + _options.contentSelector);
if (_checkNextHref(data) && !data.waiting && iTotalHeight + _options.padding >= $inner.outerHeight()) {
_debug('info', 'jScroll:', $inner.outerHeight() - iTotalHeight, 'from bottom. Loading next request...');
return _load();
}
}

查看文档，它似乎允许通过AJAX调用href中的链接并返回响应给你的功能。
如果您在pageload上进行初始调用以填充初始Feed，则使用以下内容创建display：none链接：
#nextLink {
display: none;
}
并给它一个href的数据['paging'] ['next']然后你可以用以下内容初始化无限滚动：
$('.feedContainer').infinitescroll({
// other options
nextSelector: "a#nextLink",
dataType: 'json',
appendCallback: false
}, function(json, opts) {
// Update your next link to point to the next page
$('#nextLink').attr('href',json['data']['paging']['next']);
// Add your new feed rows here
var htmlStr = '<li>FeedContent</li>';
// Append it to the container
$('.feedContainer').append(htmlStr);
});
如果支持，请使用dataType'jsonp'。
那应该粗略地给你你想要的东西！
