以下 jquery 代码在本地服务器上运行良好，但在远程服务器上不起作用。仅供参考，远程服务器正在识别 jquery。我通过我的 Stackoverflow Q 解决了这个问题
请在Merry Flowers 入场页面查看问题页面。当我输入banana8@gmail.com 作为电子邮件ID（在父信息中）并按Tab 键时，应自动填写所有后续表单元素。但这里没有这样做。
以下是来自 chrome 开发者工具的 /students/get_parent_info 的网络标头：

仅供参考，我已经验证了 banana8@gmail.com 的现有记录。
在阅读了 lazerblade 的回答后，我检查了 www 和 public_html 文件夹上的 index.php 和 test.php 。我在远程服务器上的根目录是 /home/aquinto1。我很久以前就对这些文件进行了更改。我现在没有在这里修改任何东西。
以下是我的代码：
索引.php
if (!defined('ROOT')) {
define('ROOT', DS.'home'.DS.'aquinto1');
//define('ROOT', dirname(dirname(dirname(__FILE__))));
}
/**
* The actual directory name for the "app".
*
*/
if (!defined('APP_DIR')) {
define('APP_DIR','app');
//define('APP_DIR', basename(dirname(dirname(__FILE__))));
}
/**
* The absolute path to the "cake" directory, WITHOUT a trailing DS.
*
*/
if (!defined('CAKE_CORE_INCLUDE_PATH')) {
//define('CAKE_CORE_INCLUDE_PATH', ROOT);
define('CAKE_CORE_INCLUDE_PATH', DS.'home'.DS.'aquinto1');
}
测试.php
if (!defined('ROOT')) {
define('ROOT', DS.'home'.DS.'aquinto1');
//define('ROOT', dirname(dirname(dirname(__FILE__))));
}
/**
* The actual directory name for the "app".
*
*/
if (!defined('APP_DIR')) {
define('APP_DIR','app');
//define('APP_DIR', basename(dirname(dirname(__FILE__))));
}
/**
* The absolute path to the "cake" directory, WITHOUT a trailing DS.
*
*/
if (!defined('CAKE_CORE_INCLUDE_PATH')) {
//define('CAKE_CORE_INCLUDE_PATH', ROOT);
define('CAKE_CORE_INCLUDE_PATH', DS.'home'.DS.'aquinto1');
}
<script type="text/javascript">
//var j=jQuery.noConflict();
$(document).ready(function(){
$("#MerryParentEmail").change(function(){
//txt=$("#MerryParentEmail").val();
email_id=$("#MerryParentEmail").serialize();
$.post("/students/get_parent_info",email_id,function(result_str){

student_controller 的 get_parent_info 函数和 getcities 函数：
function get_parent_info(){
//$this->layout=false;
if (!empty($this->data)){
$merryparent_info=$this->Student->MerryParent->getMerryParents($this->data['MerryParent']['email']);
print_r($merryparent_info);

echo $merryparent_info['MerryParent']['postal_code'].'*****';
}
}
function getcities(){
$this->data['MerryParent']['state_id']=$_GET['state_id'];
if (!empty($this->data['MerryParent']['state_id'])){
$cities = $this->Student->MerryParent->City->getCities($this->data['MerryParent']['state_id']);
//print_r($cities);
foreach ($cities as $k=>$v){
echo '<option value="'.$k.'">'.$v.'</option>';
}
/* foreach($cities as $optionValue){
echo '<option>' . $optionValue . '</option>';
}*/
}else{
$this->Session->setFlash('You didn\'t select a state!');
}
}
