How to make scrolling to the top of the page so that the content of the new tab is read from the beginning?

Question

JavaScript

Implemented standard tabs on the site on bootstrap3
When scrolling the page in the mobile version, they stick to the top edge and are always available. The problem is that when you switch to a new tab, the content of the tab does not start from the beginning, but from the moment where the previous tab was viewed. How to make scrolling to the top of the page so that the content of the new tab is read from the beginning?

function stickMenu() {
  var windowTop = $(window).scrollTop();
  var sectionStarts = $('#sectionStarts').offset().top;
  var sectionEnds = $('#sectionEnds').offset().top;
  if (windowTop > sectionEnds) {
    $('ul.nav.nav-tabs').removeClass('fixed');
  } else if (windowTop > sectionStarts) {
    $('ul.nav.nav-tabs').addClass('fixed');
  } else {
    $('ul.nav.nav-tabs').removeClass('fixed');
  
  }


}
