Thank you for your answers. That's my final working code (inspired by Greg and <a href="http://ajaxian.com/archives/implementing-infinite-scrolling-with-jquery" rel="nofollow noreferrer">ajaxian.com</a>), that uses some jQuery functions and works with the <a href="http://developer.yahoo.com/yui/datatable/" rel="nofollow noreferrer">YUI DataTable</a>.

<pre><code>$(".yui-dt-bd").scroll(load_more);

function load_more() { 
 if ($(this).scrollend()) {
 alert("SCROLL END REACHED !");
 // TODO load more data
 }
}

$.fn.scrollend = function() {
 return this[0].scrollHeight - this[0].scrollTop - this.height() &lt;= 0;
}
</code></pre>

My next step is to implement my own <a href="http://developer.yahoo.com/yui/paginator/" rel="nofollow noreferrer">YUI Paginator</a> to achieve a complete integration with YUI components :)

blocks|key|877944|text|我不熟悉您正在使用的特定元素，但是为了在一个完整大小的窗口上实现这一点，您可以执行以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|877945|$wnd.onscroll+=+function()+{
++++if+(($wnd.height+-+$wnd.scrollTop)+<+SOME_MARGIN)+then+doSomething();
};|code-block|syntax|javascript|877946|其中scrollTop本质上是“滚动了多少像素”。我假设将此应用于您正在使用的表将完成这项工作。|877947|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

I'm not familiar with the specific element you are using, but in order 
 to implement this on a full size window, you can do the following:

<pre><code>$wnd.onscroll = function() {
 if (($wnd.height - $wnd.scrollTop) &lt; SOME_MARGIN) then doSomething();
};
</code></pre>

Where scrollTop is essentially "how many pixels have been scrolled".
I assume applying this to the table you are working with will do the job.

blocks|key|1231039|text|我刚刚在谷歌上搜索了一下，找到了这篇文章：用Ajax、JavaScript和XML实现动态滚动。看上去是个彻底的解释。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1231040|entityMap|0|LINK|mutability|MUTABLE|url|http://www.developer.com/design/article.php/3681771^0|L|Q|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I've just googled for it and found this article: <a href="http://www.developer.com/design/article.php/3681771" rel="nofollow noreferrer">Implementing Dynamic Scroll with Ajax, JavaScript, and XML</a>. It looks like a thorough explanation.

blocks|key|882765|text|您可以看到它只运行这里+YUI。与上面建议的解决方案相比，滚动条不断移动，位置和大小反映可视区域的真实大小和位置，当滚动条到达底部时它不会加载下一批。只有当整个记录的最后一个位于查看区域的底部时，滚动条才会到达底部。当然，只有当你知道有多少记录时，这才能起作用。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|882766|entityMap|0|LINK|mutability|MUTABLE|url|http://www.satyam.com.ar/yui/2.8.0/infinite.html^0|9|2|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

You can see it working <a href="http://www.satyam.com.ar/yui/2.8.0/infinite.html" rel="nofollow noreferrer">here</a> YUI only. In contrast with one of the solutions suggested above, the scrollbar moves continuously, the position and size reflect the true size and position of the viewable area, it doesn't load the next batch when the scrollbar reaches bottom. The scrollbar reaches bottom only when the last of the whole records is at the bottom of the viewing area. Of course, this only works if you do know how many records there are.

blocks|key|877949|text|在今天阅读Firebug中的DOM属性时，我注意到了一个名为scrollY的属性(在DOM选项卡下的Firebug中，请转到content+>+scrollY)，它似乎是窗口上待滚动的像素数量。尝试查看这是否也是为可滚动元素创建的。然后，您可以使用Yuval的函数加载新数据。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|877950|entityMap^0|U|7|1Q|7|20|7|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

There is a property I noticed while reading through DOM properties in Firebug today called <code>scrollY</code> (in Firebug under the DOM tab go to <code>content</code> > <code>scrollY</code>) which appears to be the amount of pixels left to scroll on the window. Try seeing if this is also created for scrollable elements. Then you can use Yuval's function to load new data.

Ick. Not a big fan of endless scrolling; it breaks some of the key assumptions people make about how the Web works. Please promise you will only implement it under the following conditions:

1) you are not substituting it for a perfectly good page that loads everything in a nice long table and lets the user use Ctrl-F to search inside the page for what time Fringe comes on.

2) you don't plan on inserting an ad at the bottom of each chunk of scrolled data.

3) you are providing a working fallback (hey, there's that nice long table again) for blind people and people browsing the Web with JavaScript disabled.

blocks|key|231660|text|如果您使用的是YUI，那么它有一个在表滚动时触发的tableScrollEvent。将其与dataTable的generateRequest函数相结合，您可以通过观察tableScrollEvent并在接近数据集末尾时启动请求来实现无休止的滚动。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|231661|YUI文档没有针对本例的具体示例，但确实向您展示了由如何处理数据返回的generateRequest|231662|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.yahoo.com/yui/docs/YAHOO.widget.ScrollingDataTable.html#event_tableScrollEvent|1|2|http://developer.yahoo.com/yui/datatable/#data^0|P|G|0|2B|G|1|0|Q|6|2|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@$A|R|B|S|1|T]|$A|U|B|V|1|W]]|C|$]]|$1|D|3|E|5|6|7|X|8|@]|9|@$A|Y|B|Z|1|10]]|C|$]]|$1|F|3|-4|5|6|7|11|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|M]]|O|$5|I|J|K|C|$L|P]]]]

If you're using the YUI, it has a <a href="http://developer.yahoo.com/yui/docs/YAHOO.widget.ScrollingDataTable.html#event_tableScrollEvent" rel="nofollow noreferrer">tableScrollEvent</a> that gets fired when the table scrolls. Couple this with the dataTable's generateRequest function and you could implement endless scrolling by watching the <a href="http://developer.yahoo.com/yui/docs/YAHOO.widget.ScrollingDataTable.html#event_tableScrollEvent" rel="nofollow noreferrer">tableScrollEvent</a> and starting a request when you get near the end of your dataset.

The YUI doc's don't have a specific example for this case, but does show you <a href="http://developer.yahoo.com/yui/datatable/#data" rel="nofollow noreferrer">how to handle the data</a> returned by generateRequest

I am displaying a scrolled data table in a web page. This table has several thousands of dynamic rows, so it is loaded from the server (via AJAX).

The user can scroll up and down, so what I need is to detect when the user reaches the end of the scrollbar (that is, the last row at the bottom of the table) in order to request and show more data.

You can find this effect in google reader, when you scroll down to the last post in a given feed, google requests and shows new posts in a transparent way, but I can't figure out how they achieve it.

By the way, right now I am using a <a href="http://developer.yahoo.com/yui/datatable/" rel="noreferrer">YUI Datatable</a>

我在网页中显示一个滚动数据表。这个表有数千个动态行，因此它是从服务器(通过AJAX)加载的。用户可以上下滚动，所以我需要的是检测用户何时到达滚动条的末尾(即表底部的最后一行)，以便请求和显示更多数据。你可以在google阅读器中找到这种效果，当你向下滚动到给定提要中的最后一篇文章时，谷歌会以一种透明的方式请求并显示新的帖子，但我不知道它们是如何实现的。顺便说一下，我现在使用的是
