我試圖在CodeIgniter中使用FlexiGrid插件，但是當頁面顯示網格顯示，但沒有記錄，並且有一條消息說您應該等待處理，它永遠不會消失...無法讓CodeIgniter的FlexiGrid正常工作
我正在使用我自己的數據庫之一，所以我修改了部分代碼，以便在我的數據庫（id，用戶名，電子郵件）中使用字段。
Flexigrid控制器：
<?php
class Flexigrid extends CI_Controller
{
/* function Flexigrid ()
{
parent::Controller();
$this->load->helper('flexigrid');
}
*/
function __construct()
{
parent::__construct();
$this->load->helper('flexigrid');
}
function index()
{
//ver lib
/*
* 0 - display name
* 1 - width
* 2 - sortable
* 3 - align
* 4 - searchable (2 -> yes and default, 1 -> yes, 0 -> no.)
*/
$colModel['id'] = array('id', 40, TRUE, 'center', 2);
$colModel['username'] = array('username', 40, TRUE, 'center', 0);
$colModel['email'] = array('email', 180, TRUE, 'left', 1);
/*
* Aditional Parameters
*/
$gridParams = array(
'width' => 'auto',
'height' => 400,
'rp' => 15,
'rpOptions' => '[10,15,20,25,40]',
'pagestat' => 'Displaying: {from} to {to} of {total} items.',
'blockOpacity' => 0.5,
'title' => 'Hello',
'showTableToggleBtn' => true
);
/*
* 0 - display name
* 1 - bclass
* 2 - onpress
*/
$buttons[] = array('Delete', 'delete', 'test');
$buttons[] = array('separator');
$buttons[] = array('Select All', 'add', 'test');
$buttons[] = array('DeSelect All', 'delete', 'test');
$buttons[] = array('separator');
//Build js
//View helpers/flexigrid_helper.php for more information about the params on this function
$grid_js = build_grid_js('flex1', site_url("/ajax"), $colModel, 'id', 'asc', $gridParams, $buttons);
$data['js_grid'] = $grid_js;
$data['version'] = "0.36";
$data['download_file'] = "Flexigrid_CI_v0.36.rar";
$this->load->view('flexigrid', $data);
}
function example()
{
$data['version'] = "0.36";
$data['download_file'] = "Flexigrid_CI_v0.36.rar";
$this->load->view('example', $data);
}
}
?>
Flexigrid view (only changes in head to correct paths to css and js):

Ajax控制器（不得不使用非JSON擴展代碼，所以另一部分被註釋掉，根據對FlexiGrid網站上的說明另外，我是一個。修改$ recorde_item陣列時有點摸不着頭腦，因爲例如在一開始曾兩次ID我想這一定是一個錯誤，但嘗試添加第二個ID行也沒有幫助）：
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

parent::__construct();
$this->load->model('ajax_model');
$this->load->library('flexigrid');
}
function index()
{
//List of all fields that can be sortable. This is Optional.
//This prevents that a user sorts by a column that we dont want him to access, or that doesnt exist, preventing errors.
$valid_fields = array('id', 'username', 'email');
$this->flexigrid->validate_post('id', 'asc', $valid_fields);
//Get "countries"
$records = $this->ajax_model->get_countries();
//Init json build
if ($this->flexigrid->init_json_build($records['record_count'])) {
//Add records
foreach ($records['records']->result() as $row)
{

$row->username,

那麼，應該是這樣。我還必須將「擴展控制器」等更改爲「擴展CI_Controller」，因爲示例中的代碼似乎適用於舊版本的CodeIgniter。
但是，它不起作用。我只得到一個空網格。數據庫表格確實有我提到的領域。至少我自己找不到任何拼寫錯誤。這也是我在CodeIgniter中的默認數據庫，並且在其他情況下連接到它也沒有問題。它是自動加載的，所以我猜這應該會自動工作，對吧？我不應該在這裏手動連接數據庫，因爲它使用$ db變量...
任何想法然後爲什麼它不工作？
只是爲了更新，這不是我的「確切」的代碼，但它是我能夠爲codeigniter + jquery + flexigrid「學習」和「做工」的公式 – SpYk3HH
