大家好我正在创建“结算地址”“投放地址”表单。 当有人填写账单地址详细信息并且交付相同时，我想保存一个人在框中打勾以填充详细信息。
我尝试使用javascript和php验证它，它们位于表单上方的同一页面上（不在head标签中），没有任何乐趣。
*脚本更新数据库*，ajax没有得到来自php的回声，这是我无法弄清楚的另一件事。所以我有几个问题，不知道，也许有些东西干扰了网页。
我只是想知道它应该如何运作。
当我点击“提交”时--AJAX将变量发送给PHP，然后PHP更新数据库并回显字符串，然后传回给AJAX。但是AJAX看不到它，我在AJAX代码中显示的错误字符串没有显示，唯一显示的是“发生了一些错误”（我甚至在某个阶段将其更改为“成功更新”导致数据库更新：））
非常感谢任何帮助
页面名为myaccount.php
<?php
// AJAX CALLS THIS CODE TO EXECUTE
if(isset($_POST['p'])||isset($_POST['a1'])||isset($_POST['a2'])||isset($_POST['c'])||isset($_POST['co'])||isset($_POST['con'])||isset($_POST['da1'])||isset($_POST['da2'])||isset($_POST['dc'])||isset($_POST['dco'])||isset($_POST['addcheckbox'])){
require_once('./includes/mysql_connect.php');
$p = mysql_real_escape_string(trim($_POST['p']));
$a1 = mysql_real_escape_string(trim($_POST['a1']));
$a2 = mysql_real_escape_string(trim($_POST['a2']));
$c = mysql_real_escape_string(trim($_POST['c']));
$co = mysql_real_escape_string(trim($_POST['co']));
$da1 = mysql_real_escape_string(trim($_POST['da1']));
$da2 = mysql_real_escape_string(trim($_POST['da2']));
$dc = mysql_real_escape_string(trim($_POST['dc']));
$dco = mysql_real_escape_string(trim($_POST['dco']));
if(isset($_POST['addcheckbox'])=='ticked'){
$da1 = mysql_real_escape_string(trim($_POST['a1']));
$da2 = mysql_real_escape_string(trim($_POST['a2']));
$dc = mysql_real_escape_string(trim($_POST['c']));
$dco = mysql_real_escape_string(trim($_POST['co']));
}
$sql = "UPDATE customers SET address_1='$a1', address_2='$a2', phone='$p', city='$c', county='$co', country='$con', del_ad_1='$da1', del_ad_2='$da2', del_city='$dc', del_county='$dco' WHERE id_cust='$id'";
$query = mysql_query($sql);
if(!$query){
echo 'success';
exit();
}else{
echo 'not_updated';
exit();
}
}
?>
这是javascript
<script type="text/javascript" language="javascript">
function changeaddress(){
var p = _("phone").value;

_("status").innerHTML = 'updating your details ...';
var ajax = ajaxObj("POST", "/myaccount.php");
ajax.onreadystatechange = function() {
