How to load json file in codeigniter… newbie

[eluser]Ajaxboy[/eluser]
If you use Cjax (http://ellislab.com/forums/viewthread/229077/), can do this to pass data:

Code:

$("#calendar").eventCalendar({
  eventsjson: 'ajax.php?calendar/json/var1/var2'
});

Code:

Class Calendar Extends CI_Controller {

  function json($var1, $var2)
  {
    $data = array();
    
    $data['var1' = $var1;
    $data['var2'] = $var2;
    
    $data['other_data'] = 'some data';

    return $data; //return a json formatted object
  }

}
