Question

Is it possible to detect when a user is scrolling on a facebook canvas application (In a iframe).
So i can make an action when the user scrolls down on the page.

Answer 1

You can go for the jQuery API and try out their scroll() event to detect the mouse scroll…

UPDATE

$(window).load(function(){
    $($('iframe').contents()).scroll(function(){
       alert('frame scrolled in jquery');
    }); 
});
