Detect jquery event trigger by user or call by code

Question

I have some window.onscroll event

$(window).scroll(function(e){
    //My Stuff
});

but in my code I call animate scroll to some where

$('html, body').stop().animate({
   scrollTop:555
}, 1000);

so how I detect the page was scroll by user or call by my code. My current solution is put a flag before call animate in my code then clear it but it's not clever solution. I've also read about detect e.which or e.originalEvent but it's not work. I think you expert have a good solution here.

Answer 1

$('#scroller').scroll(function(e) {
    if (e.originalEvent) {
        // scroll happen manual scroll
        console.log('scroll happen manual scroll');
    } else {
        // scroll happen by call
        console.log('scroll happen by call');
    }
});

$('#scroller').scroll(); // just a initial call

When you scroll by call the e.originalEvent will undefined but when scroll manually it will give scroll object.
