问题描述
我在Joomla 1.5中覆盖了mod_mainmenu模块，并且无法获取.active或#current CSS类或ID来显示在页面上.该菜单显示以下HTML:
I'm overriding the mod_mainmenu module in Joomla 1.5 and am unable to get the .active or #current CSS class or ID to show on the page. It's showing the following HTML for the menu:
<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&view=article&id=1&Itemid=4">
<span class="embed embed-top-nav">Watch UNC-TV</span>
<p>schedule, programs</p>
</a>
</li>
</ul>
我读到mod_mainmenu会自动在其中插入active或current，这样您就可以知道哪个项目是当前活动的菜单选择.但是我在生成的HTML中看不到任何一个.我想将一些CSS应用于active元素，但是似乎没有任何方法可以做到这一点.有什么想法吗?
I've read that the mod_mainmenu will automatically insert either active or current somewhere into this so you can tell which item is the currently active menu selection. But I'm not seeing either of those in the generated HTML. I'd like to apply some CSS to the active element, but there doesn't seem to be any way to do this. Any thoughts?
谢谢.
更新:这是我创建的mod_mainmenu的代码:
UPDATE: Here's the code of the mod_mainmenu I've created:
<?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) ? array_reverse($active->tree) : null;
if (($args['end']) && ($node->attributes('level') >= $args['end']))
{
$children = $node->children();
foreach ($node->children() as $child)
{
if ($child->name() == 'ul') {
$node->removeChild($child);
}
}
}
if ($node->name() == 'ul') {
foreach ($node->children() as $child)
{
if ($child->attributes('access') > $user->get('aid', 0)) {
$node->removeChild($child);
}
}
}
if (($node->name() == 'li') && isset($node->ul)) {
$node->addAttribute('class', 'parent');
}
if (isset($path) && (in_array($node->attributes('id'), $path) || in_array($node->attributes('rel'), $path)))
{
if ($node->attributes('class')) {
$node->addAttribute('class', $node->attributes('class').' active');
} else {
$node->addAttribute('class', 'active');
}
}
else
{
if (isset($args['children']) && !$args['children'])
{
$children = $node->children();
foreach ($node->children() as $child)
{

$node->removeChild($child);
}
}
}
}
if (($node->name() == 'li') && ($id = $node->attributes('id'))) {
if ($node->attributes('class')) {
$node->addAttribute('class', $node->attributes('class').' item'.$id);
} else {
$node->addAttribute('class', 'item'.$id);
}
}
if (isset($path) && $node->attributes('id') == $path[0]) {
$node->addAttribute('id', 'current');
} else {
$node->removeAttribute('id');
}
$node->removeAttribute('rel');
$node->removeAttribute('level');
$node->removeAttribute('access');
}
define('modMainMenuXMLCallbackDefined', true);
}
ob_start();
modMainMenuHelper::render($params, 'modMyMainMenuXMLCallback');
$menu_html = ob_get_contents();
ob_end_clean();
if($params->get('menutype')=="mainmenu"){
$tag = $params->get('tag_id');
}
//output the menu!
echo fancyMenuPatch($menu_html,$tag);
?>
推荐答案
尝试一下，这是mod_mainmenu(覆盖)的代码:
Try this, here's code for mod_mainmenu (override):
<?php
// no direct access
defined('_JEXEC') or die('Restricted access');
if ( ! defined('fancyMenuPatch') )
{
function fancyMenuPatch($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 $result;
}
define('fancyMenuPatch', true);
}
if ( ! defined('modMyMainMenuXMLCallbackDefined') )
{
function modMyMainMenuXMLCallback(&$node, $args)
{
$user = &JFactory::getUser();
$menu = &JSite::getMenu();
$active = $menu->getActive();
$path = isset($active) ? array_reverse($active->tree) : null; if (($args['end']) && ($node->attributes('level') >= $args['end']))
{
$children = $node->children();
foreach ($node->children() as $child)
{
if ($child->name() == 'ul') {
$node->removeChild($child);
}
}
}
if ($node->name() == 'ul') {
foreach ($node->children() as $child)
{
if ($child->attributes('access') > $user->get('aid', 0)) {
$node->removeChild($child);
}
}
}
if (($node->name() == 'li') && isset($node->ul)) {
$node->addAttribute('class', 'parent');
}
if (isset($path) && in_array($node->attributes('id'), $path))
{
if ($node->attributes('class')) {
$node->addAttribute('class', $node->attributes('class').' active');
} else {
$node->addAttribute('class', 'active');
}
}
else
{
if (isset($args['children']) && !$args['children'])
{
$children = $node->children();
foreach ($node->children() as $child)
{
if ($child->name() == 'ul') {
$node->removeChild($child);
}
}
}
}
if (($node->name() == 'li') && ($id = $node->attributes('id'))) {
if ($node->attributes('class')) {
$node->addAttribute('class', $node->attributes('class').' item'.$id);
} else {
$node->addAttribute('class', 'item'.$id);
}
}
if (isset($path) && $node->attributes('id') == $path[0]) {
$node->addAttribute('id', 'current');
} else {
$node->removeAttribute('id');
}
$node->removeAttribute('level');
$node->removeAttribute('access');
}
define('modMyMainMenuXMLCallbackDefined', true);
}
ob_start();
modMainMenuHelper::render($params, 'modMyMainMenuXMLCallback');

echo fancyMenuPatch($menu_html,$tag);
?>
