我正在尝试将 Woocommerce 商店中的产品页面选项卡转换为手风琴式，但无法正常工作。当我点击链接时，下拉菜单不显示，它什么也不做...高度应该像我的“+”图标一样动画，但什么也没有发生。看起来它不需要在单击的元素上添加“is-open”类。所以我认为我的错误在于我的js，但我不知道在哪里！这是我的 tabs.php 文件：<?php/** * Single Product tabs * * This template can be overridden by copying it to yourtheme/woocommerce/single-product/tabs/tabs.php. * * HOWEVER, on occasion WooCommerce will need to update template files and you * (the theme developer) will need to copy the new files to your theme to * maintain compatibility.
