Question

我有一个菜单。我将功能滚动到菜单中列出的项目。我还希望所选元素显示hr。如果没有滚动功能，我会看到hr出现在所选菜单中。当菜单上单击并显示小时和滚动功能时，我需要它。让我们看一下链接2和链接3

	$('a.scrollTo').on('click', function(){

  // data-scrollTo = section scrolling to name
  var scrollTo = $(this).attr('data-scrollTo');
  
  
  // toggle active class on and off. added 1/24/17
  $( "a.scrollTo" ).each(function() {
    if(scrollTo == $(this).attr('data-scrollTo')){
      $(this).addClass('active');    
    }else{
      $(this).removeClass('active');
    }
  });
  
  
  // animate and scroll to the sectin 
  $('body, html').animate({
    
    // the magic - scroll to section
    "scrollTop": $('#'+scrollTo).offset().top
  }, 1000 );
  return false;
  
})


  var elems = document.querySelectorAll(".one,.two,.three");
for (var i = 0; i < elems.length; i++) {
  elems[i].addEventListener("click",function(e){
    if(document.querySelector(".activeOne")){
      document.querySelector(".activeOne").classList.remove("activeOne");
    }
    e.currentTarget.classList.add("activeOne");
  });
}
