JQuery UI（手风琴），在初始化时打开活动选项卡

时间：2016-03-16 14:42:51

标签： javascript jquery html opencart

我在网站上有一个基本的sidenav菜单，根据h3＆gt;这有父项和子项。 jQuery文档推荐的div结构。

我需要根据它所在的页面打开“活动”标签。 CMS已经将“活动”类应用于h3，但是我成功打开（或激活）选项卡的唯一方法是使用h3的索引，即0,1,2,3。由于我是一名新手，我一直在努力获得“活跃”h3的索引，因为大多数教程都展示了在有序列表中获取li元素索引的示例。

我的HTML看起来像这样：

<div id="accordion">
    <h3>Menu 1</h3>
    <div>sub-menu</div>
    <h3>Menu 2</h3>
    <div>sub-menu</div>
    <h3 class="active">Menu 3</h3>
    <div>sub-menu</div>
    <h3>Menu 4</h3>
    <div>sub-menu</div>
</div>

现在我知道第3个h3是索引2所以如果我需要将该标签硬编码为打开它很容易，但我需要根据哪个h3元素得到索引（没有固定的数量）有“活跃”类。

CMS是OpenCart，JQuery版本是1.10.1

阅读您的问题，不应该需要知道索引才能打开它，具体取决于页面。只需在jQuery中使用css选择器定位活动的H3，然后对其执行所需的操作，如下所示; 

 $('.accordion h3.active').next().slideDown();

示例代码，您可能需要使用.next（）打开子菜单，例如;

如果您因任何原因想要找​​到活动h3的索引，可以使用以下代码

$("#accordion h3.active").index()/2
