必应图片搜索页面 - 无限滚动 [英] Bing image search paging - infinite scroll

问题描述

当您搜索的Bing搜索引擎的图像，结果显示如下：

When you search for images on the Bing search engine, the result is displayed like this:

<一个href="http://www.bing.com/images/search?q=stack+overflow">http://www.bing.com/images/search?q=stack+overflow

请注意，你如何保持滚动，滚动并没有正常的分页。

Notice how you can keep scrolling and scrolling and there is not "normal" paging.

我的问题是：他们是如何做到这一点？我可以看到有一些Ajax / JavaScript的事件发生，但code是不容易阅读。我特别想知道他们是如何知道什么时候空箱里面的用户查看端口。

My question is: How do they do this? I can see there is some ajax/javascript events happening, but the code is not easy to read. I especially would like to know how they know when an "empty box" is inside the users view port.
