下面是用于获取一些用户输入的页面代码，SELECT 列表/下拉列表日期由代码中提到的脚本生成。脚本有效，并根据当前日期为接下来的 90 个日期填充下拉列表。
此脚本的问题是我无法使用 PHP 脚本捕获此下拉列表的值，因为“选择列表是动态生成的并且在 HTML 源代码中不可见。我不确定如何获取 ddDate 下拉列表的值另一页

PHP 脚本中的以下代码始终为空
echo "Date : ". $_POST['ddDate'];
是否可以将 ddDate onchange 事件分配给隐藏字段，以便将其存储在隐藏的输入文本字段中。
最佳答案
问题可能是 div 与 id=ddDate 和 select 与 name=ddDate。尝试为 div 或 select 元素提供不同的 id 或名称。
