如何使用 ddaccordian.init 保持当前类别选项卡保持打开状态？

Question

我有类别列表，有些有子类别，有些有子子类别，其方式如下：

Main menu
   sub menu
      sub menu

我使用< a href="http://www.dynamicdrive.com/dynamicindex17/ddaccordion.htm" rel="nofollow">ddaccordian.init 来监视打开关闭事件。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。

我尝试了以下代码：

<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>

要激活当前类别，即必须保持打开状态，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任何响应:(如果您认为我缺少 foreach 循环等，请不要介意。
我刚刚粘贴了部分代码，所以请告诉我哪里错了:(
虽然我正确地获取了当前的 URL。

您选择的手风琴插件似乎没有保持部分打开的选项，因此您必须自己拦截并停止它。它提供的唯一可能的事件是 onopenclose 但它被称为 after slideUp已经完成了，没用。

您应该选择另一个满足您需求的插件。

幸运的是，Magento 已经附带了 Prototype 和它自己的折叠类，您可以替换或 wrap 这是 sectionClicked 方法并在那里停止事件。

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，我所做的是添加这个
isCategoryActive($_category)): ?>
而不是
if($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();
                                                    ?>

                                                    <?php   foreach($childrens as $_childrens):
