How to load javascript css files in codeigniter ci

Question

i wanna migrate my website into CI. i just simply modified from ci sample file welcome.php in index() function , i load the view to show. however , i put many javascripts and css files in the header file . and call it by $this->load->view('header'); but i can not load the javascript files correctly! Can anyone give me some tips ? it;s hard to configure how to set the correct path.

<script type="text/javascript" src="/assets/javascripts/order.js"></script> 
<script type="text/javascript" src="../assets/javascripts/order.js"></script>   
<script type="text/javascript" src="../../assets/javascripts/order.js"></script>    

my controller code as following

    class Welcome extends CI_Controller {

public function index()
{
    $this->load->helper('url');     
    $this->base = $this->config->item('base_url');

    $this->load->view('header');
    $this->load->view('welcome_message');


}

}

belows are my folder structure

Answer 1

put your assets folder with applications, system, assets

not in application and simple load the url helper class in controller where you call the header view part something like

$this->load->helper('url');
$this->load->view('header');

and simply use something like this in your header file..
because $this->base_url() return the / folder..

<script src="<?php echo $this->base_url();?>assets/javascript/jquery.js"></script>

Changing the folder structure because access within the application folder is just for the core part that i know..
