在 Joomla 中突出显示活动菜单项

我正在覆盖 Joomla 1.5 中的 mod_mainmenu 模块，并且无法获取要在页面上显示的 .active 或 #current CSS 类或 ID。它显示了以下菜单 HTML： 我正在覆盖 Joomla 1.5 中的 mod_mainmenu 模块，但无法获取要在页面上显示的 .active 或 #current CSS 类或 ID。它显示了以下菜单 HTML： <ul id="top-nav" class="flatList"> <li access="0" level="1" id="1"> <a href="#"> <span class="embed embed-top-nav">Home</span> <p>news, highlights</p> </a> </li> <li access="0" level="1" id="4"> <a href="/content/index.php?option=com_content&amp;view=article&amp;id=1&amp;Itemid=4"> <span class="embed embed-top-nav">Watch UNC-TV</span> <p>schedule, programs</p> </a> </li> </ul> 我读到 mod_mainmenu 会自动在其中的某个位置插入 active 或 current ，以便您可以知道哪个项目是当前活动的菜单选择。但我在生成的 HTML 中没有看到其中任何一个。我想对活动元素应用一些 CSS，但似乎没有任何方法可以做到这一点。有什么想法吗？ 谢谢。 更新：这是我创建的mod_mainmenu的代码： <?php // no direct access defined('_JEXEC') or die('Restricted access'); if ( ! defined('fancyMenuPatch') ) { function fancyMenuPatch($result,$tag){ $menu = JSite::getMenu(); $active = $menu->getActive(); // Add to the start of the UL tag. $begin_ul = "<ul id=\"top-nav\" class=\"flatList\">"; $begin_span = "<span class=\"embed embed-top-nav\">"; $home_p = "Home</span><p>news, highlights</p></a>"; $watch_p = "Watch UNC-TV</span><p>schedule, programs</p></a>"; $learn_p = "Learn</span><p>education, unc-tv kids</p></a>"; $support_p = "Support Us</span><p>pledge, volunteer, corporate</p></a>"; $contact_p = "Contact</span><p>feedback, connect, share</p></a>"; // do the replacements $result = str_replace("<ul class=\"menu\">",$begin_ul, $result); $result = str_replace("<span>", $begin_span, $result); $result = str_replace("Home</span></a>",$home_p,$result); $result = str_replace("Watch UNC-TV</span></a>",$watch_p,$result); $result = str_replace("Learn</span></a>",$learn_p,$result); $result = str_replace("Support Us</span></a>",$support_p,$result); $result = str_replace("Contact</span></a>",$contact_p,$result); return $result; } define('fancyMenuPatch', true); } if ( ! defined('modMainMenuXMLCallbackDefined') ) { function modMainMenuXMLCallback(&$node, $args) { $user = &JFactory::getUser(); $menu = &JSite::getMenu(); $active = $menu->getActive(); $path = isset($active) ?
