我在.addClass选择选项卡时应用 CSS 类，并且它还将类添加到父父选项卡。正在添加该类，但 CSS 似乎没有对父类父类生效（如果这听起来很尴尬，请道歉）。

CSS：

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

HTML：

<!DOCTYPE html>
<html>
  <head>

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

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

jQuery：

$('.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();
});

如何获得要应用的样式？

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");
