html - 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.

Answer 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");
});
