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

我有分类列表，一些有子分类，一些有子分类，它们是这样的：

Main menu
   sub menu
      sub menu

我过去经常看开盘和收盘的比赛。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>

ddaccordion.init({
headerclass:“问题”//头组的共享CSS类名
contentclass:“theanswer”，//内容组的共享CSS类名
revealtype:“click”//当用户在标题上单击或点击鼠标时显示内容？有效值：“click”、“clickgo”或“mouseover”
mouseoverdelay:200，//如果revealtype=“mouseover”，则在标头在mouseover上展开之前以毫秒为单位设置延迟
collapseprev:false，//折叠以前的内容（因此在任何时候只打开一个）？true/false
defaultexpanded:[]，//默认打开的内容索引[index1、index2等].]表示没有内容。
onemustopen:false，//指定是否至少有一个标头应始终打开（因此从不关闭所有标头）
animatedefault:false，//默认情况下打开的内容是否应动画显示到视图中？
persiststate:false，//浏览器会话中打开内容的持久状态？
toggleclass:[“closedanswer”，“openanswer”]，//两个CSS类，分别在头折叠和展开时应用于头[“class1”，“class2”]
//togglehtml:[“prefix”、“”、“”]、//在收拢和展开标题时分别向标题添加额外的HTML[“position”、“html1”、“html2]”（请参阅文档）
animatespeed:“快”//动画速度：以毫秒为单位的整数（即：200），或关键字“快”、“正常”或“慢”
oninit:function（expandedIndies）{//头初始化时要运行的自定义代码
//无所事事
},
onopenclose：函数（头、索引、状态、isuseractivated）{//在打开或关闭头时运行的自定义代码
//无所事事
}
})

为了激活当前类别，即必须保持打开状态，我执行了以下操作：

<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回应：（如果你认为我错过了foreach循环等，那没关系。
我刚刚粘贴了部分代码，请告诉我哪里错了：（

尽管我正确地获取了当前URL。

您选择的accordion插件似乎没有保持某个部分打开的选项，因此您必须自己拦截并停止该部分。它提供的唯一可能的事件是

onopenclose

，但该事件在完成后调用，这是无用的

你应该选择另一个满足你需要的插件

---

幸运的是，Magento已经提供了Prototype和它自己的accordion类，您可以替换它，或者单击它的

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，我所做的就是加上这个

而不是

if（$currentUrl==this->getCategoryUrl（$\u 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; ?>">
