jQuery flicker when using animate-scrollTo

Question

I have a problem with the scrollTo function when it is called by a jQuery animate function.

Here my code:

$("#button").click(function(){
    $("body").animate({scrollTop: 1400},"slow");
});

When I click the button, the flicker appears before the body scrolling. For example, I'm on (scroll position) 1000, and when I clicked the button the following happened:

1. page/image on (scroll position) 1400 appears, it looks like I have already gone to (position) 1400
2. then it moves again to (position) 1000, this happens so fast and looks like a flicker
3. finally it scrolls to 1400 like a normal scroll..

On firefox it always appears, and sometimes on chrome also.

Solution 1

I had the same flickering problem. It was caused by the hash anchor in the link that triggers the function. Fixed it with preventDefault():

$("#button").click(function(e){
    e.preventDefault();
    $("body").animate({scrollTop: 1400},"slow");
});

Solution 2

<a href="#" onclick="return scrollFromTop(1400, 2000);">scroll</a>

function scrollFromTop(offset, duration) {
    $('body').stop(true).animate({scrollTop: offset}, duration);
    return false;
});

had the same problem... fixed it by returning false on the click handler

Solution 3

solved this problem by stopping the animation like this:

$('body,html').bind('scroll mousedown wheel DOMMouseScroll mousewheel keyup touchmove', function(e){
            if ( e.which > 0 || e.type == "mousedown" || e.type == "mousewheel" || e.type == "touchmove"){
                $("html,body").stop();
            }
        })
