Disabling down scrolling temporarily?

Hi,

I’m using the vertical scroll handler extension by Colin tree. I have a question, is it possible to temporarily (2 seconds) disable the negative scrolling, which is scrolling downwards and only enable positive scrolling (scrolling upwards).

Why am I asking this?

Because I’m requesting data from the server on the event {max scroll}, if the user repeatedly keeps scrolling downwards even though he’s at the bottom {maximum allowed scroll} , it ducks up with the indexing variables and returns me an error.

P.s Don’t quote me on the jargons, I hope I got them right.
