Hi guys,
I want to scroll a DIV. When the DIV scroll the the bottom, it will scroll upward and vice versa. The problem is: When it scroll to the bottom, odivScrollBarSt ockInfo.scrollT op can not be increased any more but it is still less than odivScrollBarSt ockInfo.scrollH eight!!!
In order to make it work, I have to write a funny code (bold lines).
What is the problem here?

Please look at this code
