大家好，我正在创建“帐单地址”“送货地址”表格。当有人填写帐单地址详细信息并且交货相同时，我想保存一个人来勾选框以填充详细信息。
我试图用 javascript 和 php 验证它，它们位于表单上方的同一页面上（而不是在 head 标签中），没有任何乐趣。
*脚本更新数据库 *，ajax 没有从 php 获得回声，这是我想不通的另一件事。所以我有几个问题，不知道，也许页面上有干扰。
我只是想了解它应该如何工作。
当我点击“提交”时 - AJAX 将变量发送到 PHP，然后 PHP 更新数据库并回显字符串，该字符串被传递回 AJAX。但是AJAX看不到它，我在AJAX代码中的错误字符串没有显示，唯一显示的是“发生了一些错误”（我什至在某个阶段将其更改为“成功更新”，因为数据库已更新:))
任何帮助将不胜感激
名为 myaccount.php 的页面
<?php
