顶部手风琴部分处于“活动状态”。我想实现一个基于子元素变为活动菜单的菜单。例如;如您所见，“仪表板”已设置为“活动”类，因为它是当前页面。
如果子元素具有“ active”类，如何使手风琴活动？ （如网站上的下拉菜单）
码：
<nav id="side-nav">
<div class="accordion ui-accordion ui-widget ui-helper-reset" role="tablist">
<h3 class="ui-accordion-header ui-helper-reset ui-state-default ui-accordion-header-active ui-state-active ui-corner-top ui-accordion-icons" role="tab" id="ui-accordion-1-header-0" aria-controls="ui-accordion-1-panel-0" aria-selected="true" tabindex="0">

<div class="ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom" id="ui-accordion-1-panel-1" aria-labelledby="ui-accordion-1-header-1" role="tabpanel" aria-expanded="false" aria-hidden="true" style="display: none; height: 360px;">
<a href="medication/records"><b class=""></b>Medical Records</a>
</div>
</div>
<script> $(".accordion").accordion();</script>
</nav>
最佳答案
您要为Accordian设置active选项。查看更多：http://api.jqueryui.com/accordion/#option-active
可以这样完成：
<script>
$(function() {
var activeTab = 0;
$(".accordion div").each(function(i, el) {
if ($(el).find(".active").length) {
activeTab = i;
}
});
$(".accordion").accordion({
active: activeTab
});
});
</script>
当页面加载时，具有链接的面板（以
active作为类）将打开。工作示例：https://jsfiddle.net/Twisty/76jrtx62/
