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 YUI Datatable
