Scrolling overflowed DOM elements

Because when an overflowed DOM element is first created, it always starts scrolling from the top.
However, you can scroll down an overflowed DOM element such as a Div by setting the scroll.

The follow sample is written in jQuery

$("#bigDiv").scrollTop($("#bigDiv")[0].scrollHeight - $("#bigDiv").height());

Where
$("#bigDiv")[0].scrollHeight is the full overflowed height of the content.
$("#bigDiv").height() is the height of the container.
