Codeigniter：未显示确认消息Javascript

Question

i was trying to show confirmation message using bootbox . i have download and attach the JS in my header page

<link href="<?php echo base_url('assets/css/bootbox.min.js') ?>" rel="javascript">

then, i have added the following code on controller

function index()
{
//This method will have the credentials validation
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<div class="alert alert-danger" role="alert">', '</div>');
$this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_check_database');

if($this->form_validation->run() == FALSE)
{
  //Field validation failed.  User redirected to login page
    $this->load->view('header.php');
    $this->load->view('login/content.php');
    $this->load->view('footer.php');
}
else
{
  //Go to private area
  echo "<script language=\"bootbox.min.js\">.bootbox.alert(\"Login Sukses !\");</script>";
  redirect('home', 'refresh');
}

} and here's my autoload config

$autoload['libraries'] = array('database','session','javascript');

but still the message box is not showing.

is there anything else that i should check ? or is there anything wrong in my code ?

update : i have corrected the header page into

<link href="<?php echo base_url('assets/css/bootbox.min.js') ?>" rel="javascript">

Answer 1

on the redirect page add this to be part of the html code so when it loads up it will show the popup

<script>
    window.onload = function() {
        return alert("ERRROR");
    }

</script>

and in the else condition

redirect('home', 'refresh');
