Question

当我从下拉菜单中选择其他选项时，我正试图让div中的内容发生变化。在有效之前我在div中有标签，但是它们看起来很难看，所以我把它们放在一个下拉菜单中。我将在下拉菜单中引用一个地图或网格，用户可以在以后进行此操作时查看。

}

如果您能够编写Javascript，此解决方案将起作用：

// Get all list options
var listOptions = $('ul.dropdown-menu > li > a');

// Attach "click" event
listOptions.click(function(ev) {
  var href = $(this).attr('href');

  // Find divs with content
  var divToShow = $(href);
  var contentDivs = divToShow.parent().find('.content');

  contentDivs.removeClass('active');
  divToShow.addClass('active');
});

我调整了一下代码。 Codepen可以在这里找到：http://codepen.io/anon/pen/XbMeoK。请注意，我也对CSS做了一些小改动。
