Question

我正在尝试创建一个自动填充搜索框但是这段代码不起作用，我正在尝试这三天。我需要一个自动完成搜索结果系统。我尝试了几种方法。但在我看来，我没有得到任何回应或任何错误。键入一个字母后，它不会告诉任何内容

控制器上的代码

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Search extends CI_Controller {
function __construct()
{
    parent::__construct();
}
public function index()
{
    $this->load->view('search');
}

public function getFunction()
{

if ( !isset($_GET['term']) )
 exit;
 $term = $_REQUEST['term'];
    $data = array();
    $rows = $this->model_search->getData($term);
        foreach( $rows as $row )
        {
            $data[] = array(
                'label' => $row->bname.', '. $row->bname,
                'value' => $row->bname); 
        }
    echo json_encode($data);
    flush();

}
}

和型号代码是

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Model_search extends CI_Model {
public function __construct()
{
     parent::__construct();
     // Your own constructor code

}
function getData($term)
{
     $sql = $this->db->query('select * from brands where bname like "'. mysql_real_escape_string($term) .'%" order by bname asc limit 0,10');
return $sql ->result();
 }
 }
