Question

i was reading those few lines of code from a javascript(Jquery) file and I was wondering where those arguments “x” and “y” are coming from.Is the scroll event that is taking care peraphs?

$(window).scroll(function(x,y) {

        dosomething(withThis);
    });

thanks

P.S. here is the jquery excerpt that made me ask this question Is this an elegant way to make elements fade in while scrolling?

Answer 1

Well, open Firebug console (or web dev. tools) and paste there this code:

 $(window).scroll(function(x,y,z) {
    console.log(x,y,z)
 });

After execution and scrolling you’ll see the result (works on sites with jQuery).

As expected, first argument – event object, 2nd and 3rd – undefined;

But, you can trigger events manually, and pass any arguments.
