Question

一个切换开关出现在width：912px处，通过单击一个切换开关（最大宽度：912px），您会触发垂直菜单的出现，但是当您将其变宽时，该切换开关就会消失并且会出现一个水平菜单，但是垂直菜单仍然存在（fiddle）。

function onScroll() {
  $(window).on("scroll", function() {
    if ($(window).scrollTop()) {
      $('nav').addClass('add');
    } else {
      $('nav').removeClass('add');
    }
  })
}

function clickScroll() {
  $("#toggle").click(function() {
    $(this).toggleClass("on");
    $("#content").toggleClass("click");
    $("#place").toggleClass("on");
  })
}

clickScroll();
onScroll();
