Question

我正在尝试通过将其设置为活动状态来更改导航栏项的背景颜色。应停用与左页对应的菜单项，即应将其背景颜色设置回正常。

有两个问题：

使用data-toggle="pill"时，href不再有效（因此我将其排除在外）
记住上一页无效，因为全局变量previousID未被覆盖。因此，之前选择的菜单项未被停用。

这是代码：

	var previousID = "navbar-index";
	$("li").click(function() {
	  var currentID = $(this).attr("id");
	  alert("current ID: " + currentID);
	  document.getElementById(currentID).setAttribute('class', 'active');
	  alert("previous ID: " + previousID);
	  document.getElementById(previousID).removeAttribute('class', 'active');
	  previousID = currentID;
	});
