我有类别的列表，有些子类，有些有子子类，它们是这样的：
Main menu
sub menu
sub menu
我使用ddaccordian.init来观察开放式近距离事件。一切正常，但现在我想要的是当前选定的URL类别必须保持打开状态。
我尝试过以下代码：
<script type="text/javascript">
ddaccordion.init({
headerclass: "question", //Shared CSS class name of headers group
contentclass: "theanswer", //Shared CSS class name of contents group
revealtype: "click", //Reveal content when user clicks or onmouseover the header? Valid value: "click", "clickgo", or "mouseover"
mouseoverdelay: 200, //if revealtype="mouseover", set delay in milliseconds before header expands onMouseover
collapseprev: false, //Collapse previous content (so only one open at any time)? true/false
defaultexpanded: [], //index of content(s) open by default [index1, index2, etc]. [] denotes no content.
onemustopen: false, //Specify whether at least one header should be open always (so never all headers closed)
animatedefault: false, //Should contents open by default be animated into view?
persiststate: false, //persist state of opened contents within browser session?
toggleclass: ["closedanswer", "openanswer"], //Two CSS classes to be applied to the header when it's collapsed and expanded, respectively ["class1", "class2"]
//togglehtml: ["prefix", "<img src='images/plus.gif' /> ", "<img src='images/minus.gif' />"], //Additional HTML added to the header when it's collapsed and expanded, respectively ["position", "html1", "html2"] (see docs)
animatespeed: "fast", //speed of animation: integer in milliseconds (ie: 200), or keywords "fast", "normal", or "slow"
oninit:function(expandedindices){ //custom code to run when headers have initalized
//do nothing
},
onopenclose:function(header, index, state, isuseractivated){ //custom code to run whenever a header is opened or closed
//do nothing
}
})
</script>
并且要激活当前类别，即必须保持打开，我这样做了：
<a <?php if($_category->hasChildren()): ?>class="question"<?php endif; ?><?php if ($currentUrl == $this->getCategoryUrl($_category)): ?> class="current"<?php endif; ?> href="<?php echo $this->getCategoryUrl($_category) ?>">
<?php echo $_category['name']; ?>
</a>
<?php $potential1 = $_category->hasChildren(); ?>
<?php if($_category->hasChildren()): ?>
<?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?>
<?php $_subcategories = $_category->getChildrenCategories() ?>
<ul <?php if($_subcategories): ?>class="theanswer"<?php endif; ?>>
<?php foreach($_subcategories as $subcat): ?>
<li>
<a <?php if($subcat->hasChildren()): ?>class="question"<?php endif; ?><?php if ($currentUrl == $this->getCategoryUrl($subcat)): ?> class="current"<?php endif; ?> href="<?php echo $this->getCategoryUrl($subcat); ?>">
<?php echo $subcat->getName(); ?>
</a>
<?php if($subcat->hasChildren()): ?>
<?php
$_subcat = Mage::getModel('catalog/category')->load($subcat->getId());
$childrens = $_subcat->getChildrenCategories();
?>
<ul <?php if($childrens): ?>class="theanswer"<?php endif; ?>>
<?php foreach($childrens as $_childrens): ?>
<li>
<a <?php if ($currentUrl == $this->getCategoryUrl($_childrens)): ?> class="current"<?php endif; ?>href="<?php echo $this->getCategoryUrl($_childrens); ?>">
<?php echo $_childrens->getName(); ?>
</a>
</li>
<?php endforeach; ?>
</ul>
<?php endif ?>
</li>
<?php endforeach ?>
</ul>
<?php endif ?>
</li>
但我在前端没有得到回应:(没关系，如果你认为我错过了一个foreach循环等。
我刚刚粘贴了一部分代码，告诉我哪里错了:(
虽然我正确地获取了当前的URL。

你选择的手风琴插件似乎没有保持一个部分打开的选项，所以你必须自己拦截它并阻止它。它提供的唯一可能事件是onopenclose，但在 slideUp完成后称为，这是无用的。
您应该选择另一个满足您需求的插件。
幸运的是Magento已经附带Prototype和它自己的手风琴类，你可以替换或wrap它的sectionClicked方法并在那里停止活动。
Accordion.prototype.sectionClicked = function(event) {
var element = $(Event.element(event)).up('.section');
if (!element.hasClassName('current')) {
this.openSection(element);
}
Event.stop(event);
};

这解决了我的问题，我所做的就是添加了这个
<?php if ($this->isCategoryActive($_category)): ?>
代替
if($currentUrl == $this->getCategoryUrl($_category)): ?>并在底部添加了Css类。
<div class="content-links">
<ul>
<?php $i=0; foreach ($catlist as $_category): ?>
<?php if($_category->getIsActive()): ?>
<li>
<a <?php if($_category->hasChildren()): ?>class="question"<?php endif; ?> href="<?php echo $this->getCategoryUrl($_category) ?>">
<?php echo $_category['name']; ?>
</a>
<?php $potential1 = $_category->hasChildren(); ?>
<?php if($_category->hasChildren()): ?>
<?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?>
<?php $_subcategories = $_category->getChildrenCategories() ?>
<ul class="<?php if($_subcategories): ?>theanswer<?php endif; ?><?php //if($currentUrl == $this->getCategoryUrl($_category)): ?><?php if ($this->isCategoryActive($_category)): ?> opened<?php endif; ?>">
<?php foreach($_subcategories as $subcat): ?>
<li>
<a <?php if($subcat->hasChildren()): ?>class="question"<?php endif; ?> href="<?php echo $this->getCategoryUrl($subcat); ?>">
<?php echo $subcat->getName(); ?>
</a>
<?php if($subcat->hasChildren()): ?>
<?php
$_subcat = Mage::getModel('catalog/category')->load($subcat->getId());
$childrens = $_subcat->getChildrenCategories();
?>
<ul class="<?php if($childrens): ?>theanswer<?php endif; ?><?php if ($this->isCategoryActive($_subcat)): ?> opened<?php endif; ?>">
<?php foreach($childrens as $_childrens):
?>
<li>
<a <?php if ($currentUrl == $this->getCategoryUrl($_childrens)): ?>class="current"<?php endif; ?>href="<?php echo $this->getCategoryUrl($_childrens); ?>">
<?php echo $_childrens->getName(); ?>
</a>
</li>
<?php
endforeach;
echo "</ul>";
?>
<?php endif ?>
</li>
<?php endforeach ?>
</ul>
<?php endif ?>
</li>
<?php endif ?>
<?php endforeach ?>
