CI中如何让js调用php中的变量
控制器:

class Index extends CI_Controller
{  
 // 构造函数
 function __construct()
 {
  parent::__construct();
  
  // 载入url类和模板解析类
  $this->load->helper('url');
  $this->load->library('parser');
 }
 
 // 首页(默认展现合肥地区)
 function index($locat = 'hf')
 {  
  $data = array(
  'locat' => $locat,
  );

  $this->parser->parse('index', $data);
 }
}


view下index.php中有一段js,想调用$locat变量的值


jQuery(function($){
 $("#count_p").parent("div").hide(); //消除
 $("#menu #$locat").attr("class", "selected");
});


这么写无法实现,该怎么写才行?望高手指教

------解决方案--------------------
// 首页(默认展现合肥地区)
 function index($locat = 'hf')
 {
$data['locat'] = $locat;

$this->parser->parse('index', $data);
 }


view 里面js里面 var a = ;
