Without using Ajax, you can only pass that variable through your view. Imagine the following scenario:

function yourController()
{
  $data['lat'] = 'http://google.com';
  $this->load->view('yourView/index', $data);
}

<html>
  <head>
  </head>
  <body>
     <script>
        function show()
        {
           window.location.href = '<?php echo $lat; ?>';
        }
     </script>
  </body>
</html>

var lat = '<?php echo $lat;?>';
show(lat);
function show(lat){
  location.href = 'something.com?latval='+lat;
}

are you sending url from controller to view and you want to have it in js.

Actually i have several other javascript variables which i have passed to a link with window.location.href..... now i need to add this $lat variable as a parameter to that link. $lat variable was passed in current view from controller.

something like these stackoverflow.com/questions/13085388/… . do concat the lat value.
