嵌套手风琴不会以 h2 作为链接关闭

您正在检查是否jQuery(e.target).is('.active')，然后将active类添加到 jQuery（this） 中，这些类不相同，将 e.target（和 f.target）更改为 this，它将起作用：

（检查代码段中的控制台）

jQuery(document).ready(function() {
  function close_accordion_section() {
    jQuery('.accordion .accordion-section-title').removeClass('active');

您单击的是h2/h3元素，而不是a元素。你可以

1. 像这样将h2/h3移出a：

   <div class="accordion-section">
      <h2>
        <a class="accordion-section-title" href="#accordion-3">
         Tab 1 click here
       </a>
     </h2>
    ......
   

   （这将需要编辑您的 css）

或

2. 将所有e.target和f.target替换为e.target.parentNode和f.target.parentNode，以便在单击h2、h3元素时实际检查a元素。
