Question

所以我正在尝试构建我的网站，并且我有一个非常好的粘性标题，我试图得到一种滚动间谍效果，不使用bootstrap。如果有意义的话，我希望查看导航的当前部分用活动类突出显示。

问题是，我有0个jquery知识，因此我从youtube视频中复制了一些代码，但我无法有效地实现它。有人可以更正此查询代码，使其在导航栏中突出显示当前正在查看的部分，并在用户滚动到另一部分时更新，因此该部分在导航栏中突出显示？

Ps - 我再说一遍，我不想与bootstrap xD

有任何关系

这是我的代码笔链接http://codepen.io/anon/pen/bZmRZN

Any help would be amazing!

你忘了在$之前调用(function() {来调用jQuery。虽然它在片段上没有显示但是我在我的服务器上试了它并且工作正常〜在你的服务器上尝试它：）

$(function() {
	var navLinks = $('nav ul li a'),
			navH = $('nav').height(),
			section = $('section'),
			documentEl = $(document);

	documentEl.on('scroll', function() {
			var currentScrollPos = documentEl.scrollTop();

			section.each(function() {
					var self = $(this);
					if ( self.offset().top < (currentScrollPos + navH) && (currentScrollPos + navH) < (self.offset().top + self.outerHeight()) ) {
							var targetClass = '.' + self.attr('class') + '-marker';
							navLinks.removeClass('active');
							$(targetClass).addClass('active');
					}
			});

	});
})();
