[dhavald99]

Hi,
I m using infinite scroll with reverse for chating in my site. there are multiple infinite scroll in a page. so i want to pass my conversation id to @load function.
can any one please tell me how to pass that ?

because when i am trying to pass @load=“onLoad($evetnt, conversation_id, ($done ???))” . i m note getting that done function there.

Thank in advance!
