Question

我有一个带有嵌套列表项的菜单。当您单击li时，将通过添加当前类并将其删除到其他位置来显示内容。当您单击嵌套的li时，问题就起作用了。单击嵌套的li时，内容不会显示。谁能给我一些急需的指导，因为我是使用jQuery的新手。我试图缩小多余的代码，以便于查看。谢谢

假设我已正确理解您的问题，则可以使用默认Event对象的stopPropagation方法来确保仅特定列表项具有应用的类。下面的示例：

$(document).ready(function() {
  $('.profile_manager_nav_items_list li').click(function(evt) {
    evt.stopPropagation(); // stop the event bubbling
    var tab_id = $(this).attr('data-tab');

    $('.profile_manager_nav_items_list li').removeClass('current_profile_manager_tab');
    $('.profile_manager_tab_content').removeClass('current_profile_manager_tab');

    $(this).addClass('current_profile_manager_tab');
    $("#"+tab_id).addClass('current_profile_manager_tab');
  }); 
});

.current_profile_manager_tab {
  background-color: #808080;
}
