html - 单击菜单后如何添加CSS类并突出显示当前菜单

Question

我在这里使用带有多个 css 类的自定义 Bootstrap 导航栏。我发现在所选元素菜单上添加事件 (menu__item--current) 类时遇到困难。我在底部添加了 jquery 代码.

        </ul>
      </nav>
    </div>
  </nav>
</div>

<script type="text/javascript">

$(document).ready(function () {
    $('ul.nav > li').click(function () {
      
        $('ul.nav > li').removeClass('menu__item--current');
        $(this).addClass('menu__item--current');                
    });            
});
</script>

它工作正常你需要像这样添加css

$(document).ready(function () {
    $('ul.nav > li').click(function () {
      
        $('ul.nav > li').removeClass('menu__item--current');
        $(this).addClass('menu__item--current');                
    });            
});

.menu__item--current a{
  color:#ee5500!important;
}
