<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <ul class="nav navbar-nav navbar-right">
          <li class="hidden">
            <a href="./#top"></a>

JS逻辑

Meteor.startup(function() {


  var controller = new ScrollMagic.Controller();

  controller.scrollTo(function(target) {
    TweenMax.to(window, 0.5, {
      scrollTo: {
        y: target, 
        autoKill: true
      },
      ease: Cubic.easeInOut
    });


  console.log("in here");

  });


  $(document).on("click", "a[href^=#]", function(e) {
  var id = $(this).attr("href");

  if($(id).length > 0) {
    e.preventDefault();

    // trigger scroll
    controller.scrollTo(id);

    // If supported by the browser we can also update the URL
    if (window.history && window.history.pushState) {
      history.pushState("", document.title, id);
    }
  }

});
