我使用带有AppUI 2.1 bootstrap主题的codeigniter 3.0创建了一个登录，它总是在登录时显示错误div，每次我成功登录时，它也会成功导向到Maps视图，但是当我导航到Information Table视图时返回地图视图，它将重定向到登录视图。
有什么建议吗？这是我的代码：
模型/ Login_model.php
class Login_model extends CI_Model {
public function login($username, $password) {
$passwordEncrypt = sha1($password);
$this->db->where('username', $username);
$this->db->where('password', $passwordEncrypt);
$query = $this->db->get('admin');
if ($query->num_rows() == 1) {
foreach ($query->result() as $row) {
$data = array(
'username' => $row->username,
'password' => $row->password,
'logged_in' => true
);
}
$this->load->library('session');
$this->session->set_userdata($data);
return true;
} else {
return false;
}
}
public function isLoggedIn() {
header("cache-Control: no-store, no-cache, must-revalidate");
header("cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
$is_logged_in = $this->session->userdata('logged_in');
if (!isset($is_logged_in) || $is_logged_in !== true) {
redirect('/');
exit;
}
}
}

'login-username': {

$("#form-login").submit(function (e){
e.preventDefault();
var url = $(this).attr('action');
var method = $(this).attr('method');
var data = $(this).serialize();
$.ajax({
url:url,
type:method,
data:data
}).done(function(data){
if(data !=='')
{
$("#response").show('fast');
$("#response").effect( "shake" );
$('#form-login')[0].reset();
}
else
{
window.location.href = url;
throw new Error('go');
}
});
});
$( "div" ).each(function( index ) {
var cl = $(this).attr('class');
if(cl ==='')
{
$(this).hide();
}
});
}
};
}（）;
在$（'＃form-login'）。submit（function（e）{}）之间的readyLogin.js中，似乎其中的代码不起作用。
