Simulate scroll event using Javascript

Question

I am trying to Simulate a scroll event using Javascript for Mobile Safari. I am using the following code

var evt = document.createEvent("MouseEvents"         


        

Answer 1

The event that worked for me was mousewheel, and the 5th parameter needs to be positive for scrolldown and negative for scrollup.

var evt = document.createEvent("MouseEvents");    
evt.initMouseEvent("mousewheel", true, true, window, 1, 0, 0, 0, 0, false, false, false, false, 0, null);

Note that the event type is DOMMouseScroll for FireFox.
