how to use jQuery in Code Igniter 2.x.x?

In my config file I have $config['jque开发者_如何学编程ry'] = 'js/jquery.js';

My jquery.js file resides outside of the application folder, and is inside the js folder

In my controller I have

public $jquery

public function __construct(){
  $this->jquery = $this->config->item('jquery');
}

public function index(){
  $data['jquery'] = $this->jquery;
  $this->load->view('site_view',$data);
}

In my view file I have

<script type="text/javascript" src='<?php echo "$base/$jquery" ;?>'></script>

Now the question is,

When I do some basic jQuery scripts why does it not work?

I tried adding an external js.js file which contains a very basic jquery script for checking a box and disabling a button.

It doesn't work unless I use vanilla javascript in the view file itself.

I don't know what's going on, I even included the js folder at the htaccess

RewriteCond $1 !^(index\.php|images|css|js|robots\.txt)

Anyone knows what is happening? In other frameworks I never had problems including jquery at all.

Look at your source,

You are using an absolute path instead of a valid http:// path try using site_url like so

<?php echo site_url($jquery);?>

Note that this assumes your setup looks something like

/
/Application
/System
/Css
/js
/index.php
/.htaccess
