Why doesn't this feature work on iPhones?

Question

JavaScript

Why does this code work everywhere except for iOS devices? Doesn't work on iphone in safari or chrome. Help me please.

function scrollToElem(elem) {
    var st = $('body').scrollTop() || $('html').scrollTop();

    $('body, html').animate({
      scrollTop: ($(elem).offset().top + st) + "px"
    }, 2000);
}
