auto scroll to bottom of page with jquery

This will work in every case, no need to put a 'ridiculous' number in it:

$(document).scrollTop($(document).height());

To cover all scenarios: Consider scrolling an overflowed div where height is not the same as scrollHeight. (remove the animate part if its not needed):

$('#myDiv').animate({
    scrollTop: $('#myDiv').get(0).scrollHeight
}, 1500);

This Code work for me:-

jQuery("html, body").animate({ scrollTop: jQuery(window).height()}, 1500);

Try the ScrollTo plugin

function scroll(){
  $('html, body').animate({
    scrollTop: $("#footerOfPage").offset().top
  }, 0);
}
