Using the remote function of jquery validation

Question

I\'m trying to figure out how I can turn this:

$(\'#username\').blur(function(){
    $.post(\'register/isUsernameAvailable\', 
           {\"username\":$(\'#

I think I am too late to reply. but our code is very easy for all

Validation Code

rules: {
            session: {
               required: true,
                remote: {
                    url: "",
                    type: "post",
                    data: {
                      session: function() {
                        return $( "#sessionInput" ).val();
                      }
                    }
                  }
            },
        },

Controller Code

public function checkSession()
    {
        $response = array();
        $session = $this->input->post('session');

        $check = $this->dm->checkData('session','session',array('session'=>$session));

        if($check)
        {
            echo(json_encode("Session Already Exist")); 
        }
        else
        {
            echo(json_encode(true)); 
        }
    }

Model Code

public function checkData($data,$tablename,$where)
    {
        $query = $this->db->select($data)
                 ->from($tablename)
                 ->where($where)
                 ->get();
        if($query->num_rows() > 0)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
