Go to top of page using jQuery

This one liner jQuery snippet will force your browser to go to the top of your page:

$('html, body').animate({ scrollTop: 0 }, 0);

If you want to add some smooth scrolling:
$('html, body').animate({ scrollTop: 0 }, 'slow');

%input.btnCancel{:type => "reset", :value => "Reset without saving", :id => "reset"}

 $('#reset').click(function() {
    $('html, body').animate({ scrollTop: 0 }, 0);
    location.reload().scrollTop(0);
  });
