The functionality of Bootstrap scroll spy is compromised when used with the javascript implementation or the content within the <body> element

Check out this simplified version of my project on a fiddle. Even though it is set up correctly, it doesn't seem to work at all.

https://jsfiddle.net/ybarpz3x/8/

I've spent the last 3 days trying to debug this issue but I just can't seem to figure it out. I have included jquery, bootstrap js, and bootstrap css, created my own .active class, and tried implementing

<body data-spy="scroll" .. >
along with the javascript mentioned in the jsfiddle link.

Please assist me, thank you.

$(document).ready(function(){
  // Cache selectors
  var lastId,
      topMenu = $("#navmenu"),
      topMenuHeight = topMenu.outerHeight()+15,
      // All list items
      menuItems = topMenu.find("a"),
      // Anchors corresponding to menu items
      scrollItems = menuItems.map(function(){
        var item = $($(this).attr("href"));
        if (item.length) { return item; }
      });

  // Bind click handler to menu items
  // so we can get a fancy scroll animation
  menuItems.click(function(e){
    var href = $(this).attr("href"),
        offsetTop = href === "#" ? 0 : $(href).offset().top-topMenuHeight+1;
    $('html, body').stop().animate({ 
      scrollTop: offsetTop
    }, 300);
    e.preventDefault();
  });

  var navHeight = $("#navmenu").outerHeight(true) ;

  // Bind to scroll
  $(window).scroll(function(){
    // Get container scroll position
    var fromTop = $(this).scrollTop()+navHeight;

    var navCollapse = 450;

    if (fromTop > navCollapse) {
      $("nav li").addClass("top-menu-collapsed")
    };

    if (fromTop <= navCollapse) {
      $("nav li").removeClass("top-menu-collapsed")
    };             
  });

  // Add scrollspy to <body>
});
$('window').load(function(){
  $('body').scrollspy({target: '#navmenu', offset: navHeight});
});

The documentation for Bootstrap states that scrollspy functionality depends on the presence of a 'nav' component within the Bootstrap framework. You can learn more about it by visiting this link.
