我正在尝试在表单上设置一个自动完成输入框，尽管一切似乎都正常，但我没有收到任何数据传递到输入框。Firebug 报告成功，但那里什么也没有。我想知道是否有人可以查看我的代码，看看是否有任何明显的错误可能导致它。

脚本是：

(function($){
    $("#town").autocomplete({
        source :"drivers/driver_gettown",
        minLength : 3,
        dataType:'JSON',
        type:'POST'
    });
})(jQuery);

输入框是：

   <div class="div">
        <input name="town" id="town"  type="text" class="txtSelect input required" value="<?php echo set_value('town'); ?>" />
        <?php echo form_error('town'); ?>
    </div>

型号为：

class Driver_model extends CI_Model
{
    public function __construct() {
        // Load the Database
        parent::__construct();
        $this->load->database();
    }


    function driver_get_towns($q)
    {
        // Get a list of Towns
        // Search for row "place_name" from Table called "tbk_towns"
        $this->db->select('place_name');
        $this->db->like('place_name', $q);
        $query = $this->db->get('tbk_towns');
        if($query->num_rows > 0)
        {
            foreach ($query->result_array() as $row)
            {
                //build an array for the towns
                $row_set[] = htmlentities(ucfirst($row['place_name'])); 
            }
            //format the array into json data
            // header('Content-Type: application/x-json; charset=utf-8');
            // echo json_encode($row_set);
            $this->output
                    ->set_content_type('application/json')
                    ->set_output(json_encode($row_set)); 
        }
    }
}

最后是控制器：

class Drivers extends CI_Controller 
{

    function __construct() 
    {
        parent::__construct();
        $this->load->model('driver_model');
        $this->load->helper('url', 'form', 'html', 'json');
    }

    function index()
    {
        // Just loads the main Page of the Drivers Area
        $data['metatitle'] = "Auto Ninja | Drivers Members Area | Locally Rated Garages &amp; Mechanics";
        $data['metadescription'] = "Garages &amp Mechanics";
        $data['metakeywords'] = "Car Repair, Car Service, Car MOT";
        $this->load->view('drivers/header_drivers.inc.php', $data);
        $this->load->view('drivers/index');
        $this->load->view('drivers/footer_index.inc.php');
    }


    public function driver_gettown()
    {
        if (isset($_GET['term'])){
            exit;
        }
        $this->load->model('driver_model');
        $q = ucfirst($_GET['term']);
        $this->driver_model->driver_get_towns($q);
    }

}

和评论/帮助将不胜感激。

function driver_addjob()
    {
        // Loads the Add New Job Form for the Website
        $this->load->helper('form');
        $this->load->library(array('form_validation', 'session'));
        $this->load->model('driver_model');
        $this ->form_validation->set_error_delimiters('<span class="error">', '</span>');
        // Validate the form fields
        $this->form_validation->set_rules('town', 'Nearest Town or City', 'trim|required|xss_clean');
        // Populates dropdown "town" from the database  ???

        if ($this->form_validation->run() == FALSE)

        {
            $data['metatitle'] = "Auto Ninja | Drivers - Add New Job | Locally Rated Garages &amp; Mechanics";
            $data['metadescription'] = "Garages &amp Mechanics";
            $data['metakeywords'] = "Car Repair, Car Service, Car MOT";
            $this->load->view('drivers/header_drivers.inc.php', $data);
            $this->load->view('drivers/driver_addjob.php');
            $this->load->view('drivers/footer_index.inc.php');
        }
        else 
        {
            $townid = $this->input->post('town');
            $work_jobtitle = $this->input->post('jobtitle');
            $this->driver_model->driver_add_job ($townid);
            $this->session->set_flashdata('message', 'your work request has been added to the system');
            $data['metatitle'] = "Auto Ninja | Drivers - Add New Jobs Success | Locally Rated Garages &amp; Mechanics";
            $data['metadescription'] = "Garages &amp Mechanics";
            $data['metakeywords'] = "Car Repair, Car Service, Car MOT";
            $this->load->view('drivers/header_drivers.inc.php', $data);
            $this->load->view('drivers/driver_addjob_success');
            $this->load->view('drivers/footer_index.inc.php');
        }

    }

好的，我终于想通了。出于某种原因，响应 URL 出现在 http://php.codeigniter.server/drivers/drivers/driver_gettown?term=ed

所以控制器被添加了两次。我将Java更新为

(function($){
    $("#town").autocomplete({
        source :"driver_gettown",
        minLength : 3,
        dataType:'JSON',
        type:'POST'
    });
})(jQuery);

ie not including the controller and it works!!! So a tad confused as to how it knows which controller to find the method in but who cares it works. It would be nice to know though as it will probably still annoy me... Possibly the JSON call bring it over in the URL maby?
