jQuery 手风琴只能以奇数顺序工作

如何解决jQuery 手风琴只能以奇数顺序工作

我在 WordWress 模板中使用 w3school 的 jQuery 手风琴，同时获取帖子格式，手风琴只能在奇数位置工作，唯一有效的手风琴是第 1、第 3、第 5 等..
这是手风琴的脚本：

<script>
var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
  acc[i].addEventListener("click",function() {
    this.classList.toggle("active");
    var panel = this.nextElementSibling;
    if (panel.style.maxHeight) {
      panel.style.maxHeight = null;
    } else {
      panel.style.maxHeight = panel.scrollHeight + "px";
    } 
  });
}
</script>

这里是模板的代码

<?PHP $display = roogan_get_episode_layout_options('e'); ?>

<article <?PHP post_class('roogan-item roogan-post section-item-vertical-rhythm roogan-layout-e roogan-is-podcast'); ?>>
    <div class="row justify-content-center">

        <div class="col-12 col-md-6 col-lg-6"> 
            <?PHP if ( $fimg = roogan_get_featured_image( 'roogan-e' ) ): ?>

            <?PHP roogan_play_button( 'roogan-button-play roogan-button-play-white roogan-button-play-large',false ); ?>
                    <?PHP endif; ?>
