jQuery .scrollTop(); + animation

Try this code:

$('.Classname').click(function(){
    $("html, body").animate({ scrollTop: 0 }, 600);
    return false;
});

To do this, you can set a callback function for the animate command which will execute after the scroll animation has finished.

For example:

var body = $("html, body");
body.stop().animate({scrollTop:0}, 500, 'swing', function() { 
   alert("Finished animating");
});

Where that alert code is, you can execute more javascript to add in further animation.

Also, the 'swing' is there to set the easing. Check out http://api.jquery.com/animate/ for more info.
