Question

当选择了一个选项卡时，我正在使用.addClass应用CSS类，并且它还将该类添加到父项父选项卡。正在添加该类，但CSS似乎没有生成父类的父类（如果听起来很尴尬，请道歉）。

CSS：

.selectedTab{
  color:#234 !important;
  background-color:white !important;
}

HTML：

      </ul>
    </nav>
    <div class="content" id="home">home</div>
    <div class="content" id="armagh">armagh</div>
    <div class="content" id="antrim">antrim</div>

  </div>
  </body>
</html>

jQuery的：

$('.contentLinks').click(function() {
  $(this).addClass("selectedTab");
  $('a').not(this).removeClass("selectedTab");
  //var is_element_li = $(this).parent().parent().get(0).tagName.is("li");
  var is_element_li = $(this).parent().parent().is("li");
  if(is_element_li){
    $(this).parent().parent().addClass("selectedTab");
  }
  var nameAttribute = $(this).attr('name');
  nameAttribute = "#"+ nameAttribute;
  $(nameAttribute).show();  
  $('div.content').not(nameAttribute).hide();
});

我如何才能申请这种风格？

您需要将selectedTab类添加到锚元素，而不是li元素：

$(this).parent().parent().children("a").addClass("selectedTab");
