我有一个奇怪的问题。我正在修复一个网页。在某些页面中，jquery 加载了以下行
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
在 Internet Explorer 中，如果我加载包含此行的页面，然后单击网页中的其他位置，则无论用户在何处注销都无关紧要。貌似这个函数最后才执行（使用PHP语言）
function logout()
{
global $db;
session_start();
/* Delete the user from table online */
mysql_query("DELETE FROM online WHERE user_id='$_SESSION[user_id]'");
/* Update the table last seen in table users */
$date_now = date("Y-m-d");
$time_now = date("H:i");
$date_last_seen = $date_now. ' '. $time_now;
mysql_query("UPDATE users SET date_last_seen = '$date_last_seen'
WHERE id='$_SESSION[user_id]'");
if(isset($_SESSION['user_id']) || isset($_COOKIE['user_id'])) {
mysql_query("update `users` set `ckey`= '', `ctime`= ''
where `id`='$_SESSION[user_id]' OR `id` = '$_COOKIE[user_id]'") or die(mysql_error());
}
/************ Delete the sessions****************/
unset($_SESSION['user_id']);
unset($_SESSION['user_name']);
unset($_SESSION['user_level']);
unset($_SESSION['HTTP_USER_AGENT']);
session_unset();
session_destroy();
/* Delete the cookies*******************/
setcookie("user_id", '', time()-60*60*24*COOKIE_TIME_OUT, "/");
setcookie("user_name", '', time()-60*60*24*COOKIE_TIME_OUT, "/");
setcookie("user_key", '', time()-60*60*24*COOKIE_TIME_OUT, "/");
header("Location: index.php");
}
会话被销毁，用户会话从数据库中删除，页面被重定向到 index.php。如果在登录页面中选择“记住我”以保存 cookie，则该页面可以正常工作。
在我加载 jquery 的 2 个不同页面中，我在顶部添加了这一行
<?php
session_set_cookie_params(1800);
session_start();
?>
它正确保存了会话 cookie，但最终没有任何反应，因为用户再次注销。
jquery 仅在 2 个页面中加载，仅在需要时加载。我试图把它放在通用标题上，但同样的问题发生了。当我删除 jquery 行时，页面工作正常，当然需要它的功能除外。所以这就像一个死胡同。
我提醒这仅在 IE 上发生（在 IE 8 和 IE 10 上测试）。在其他浏览器中它工作正常
这是应该在其中一个页面中执行的 jquery 代码

这是gallerrific jquery插件
有任何想法吗？谢谢
