Could you point how to make a Codeigniter view to obtain a value from the correspondent controller?

public function get($id)
    {
        try {
            if (empty($id))
                throw new Exception('ID não existe', 1);
            if (!$this->input->is_ajax_request())
                throw new Exception('Erro de requisição', 1);
    
            $result = (array )current($this->reclamacao_model->new_get(array('where' =>array('id_reclamacao' =>           $id),'fields'=>array('id_reclamacao','data','nome_reclamante',
                    'genero', 'procedencia', 'anexo', 'fk_seguradora', 'created_at',
                    'created_by', 'updated_at', 'updated_by')               
                    )));
           
        }
        catch (exception $e) {
            bootbox_alert($e->getMessage());
        }
        $this->output->set_content_type('application/json')->set_output(json_encode($result));
    }

<!-- Existing value -->	
<input type="hidden" id="id_reclamacao" name="id_reclamacao" value="">	
...
	
<!----------------------------------------------------------------------------------------------------->
I guess an ajax code is needed to receive the value in the view, isn't it? 
Something like that:
<!----------------------------------------------------------------------------------------------------->
<script type="text/javascript">

		$(function () {
			
				var serv = $('#id_reclamacao').val();
	
				$.ajax({
					url: base_url('reclamacao/get/' + serv),
					type: 'post',
					cache: false,
					contentType: false,
					processData: false,
					dataType: 'json',
					data: serv,
					success: function (data) {
						// THE WAY TO OBTAIN THE RESULT HERE IS CORRECT?
						$('#anexo').val(data);
					},
					error: function(jqXHR) {
						bootbox.alert(jqXHR.responseText);
					}
				});

			});
		});
</script>
