• 1: Follow in how to setup smarty as a template engine in CodeIgniter.
• 2: Download XAjAX and extract it.
• 3: Copy the folder xajax_core into /system/application/libraries
• 4: Create a library class The_xajax.php:

  
  if (!defined('BASEPATH')) exit('No direct script access allowed');
  
  require "xajax_core/xajax.inc.php";
  
  class The_xajax extends xajax
  {
      function The_xajax()
      {
          $this->xajax();
      }
      
      function loadJavascriptForSmarty($theSmarty)
      {
          $theSmarty->assign( 'the_xajax_js', $this->getJavascript(base_url()) );
      }
      
  } // END class The_xajax
  

• 5: The controller hello.php:

  
  load->library('the_xajax');
  	$this->the_xajax->registerFunction(array('test_function',&$this,'test_function'));
  	$this->the_xajax->loadJavascriptForSmarty($this->mysmarty);
  	$this->the_xajax->processRequest();
      }
      
      function index() {
  	$this->mysmarty->view( 'hello' );
      }
  
      function test_function()
      {
          $objResponse = new xajaxResponse();
          $objResponse->Assign("SomeElementId","innerHTML", "Hello world";
          return $objResponse;
      }
  }
  

• 6: And within the view template hello.tpl add to the header:

  
      {$my_xajax_js}
  

  And within the body:

  
      <div id="SomeElementId">TEST</div>
  
      <input type="button" value="test" onclick="xajax_test_function(2);">
  

Error using $config['global_xss_filtering'] = TRUE; together with XAjAX

class My_Input extends CI_Input
{
	var $never_allowed_str = array(
									'document.cookie'	=> '[removed]',
									'document.write'	=> '[removed]',
									'.parentNode'		=> '[removed]',
									'.innerHTML'		=> '[removed]',
									'window.location'	=> '[removed]',
									'-moz-binding'		=> '[removed]',
									''				=> '-->',
									#'<![CDATA['			=> '&lt;![CDATA['
									);
    
}

For sure, you weak the security by doing so.
