【IT168专稿】当前在Web开发中，jQuery和PHP无疑是较好的配合。其中PHP由于其简单易用，深得开发者的喜爱，而jQuery则由于在前端开发中的灵活和简单，功能强大，可以做出很多很眩目的效果。在上篇文章中，主要讲述了设计表格基类，本文将主要介绍测试和运行部分，以及加入AJAX功能，整合jQuery。
测试运行
现在，我们可以在CI中测试运行下我们所写的数据表格助手类是否有效果，在测试前，先在MYSQL中建立数据表如下：
CREATE DATABASE `dg_test`;
CREATE TABLE `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(80) NOT NULL,
`password` varchar(32) NOT NULL,
`email` varchar(255) NOT NULL,
UNIQUE KEY `id` (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ;
CREATE TABLE `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(80) NOT NULL,
`password` varchar(32) NOT NULL,
`email` varchar(255) NOT NULL,
UNIQUE KEY `id` (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ;
并插入一些初始数据
INSERT INTO `users` (`id`, `username`, `password`, `email`) VALUES
(1, 'david', '12345', 'david@domain.com'),
(2, 'maria', '464y3y', 'maria@domain.com'),
(3, 'alejandro', 'a42352fawet', 'alejandro@domain.com'),
(4, 'emma', 'f22a3455b2', 'emma@domain.com'
(1, 'david', '12345', 'david@domain.com'),
(2, 'maria', '464y3y', 'maria@domain.com'),
(3, 'alejandro', 'a42352fawet', 'alejandro@domain.com'),
(4, 'emma', 'f22a3455b2', 'emma@domain.com'
接下来，编写控制层的测试文件，命名为test.php,保存在application/controller目录下，代码如下：
class Test extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->helper(array('datagrid','url'));
$this->Datagrid = new Datagrid('users','id');
}
function index(){
$this->load->helper('form');
$this->load->library('session');
$this->Datagrid->hidePkCol(true);
$this->Datagrid->setHeadings(array('email'=>'E-mail'));
$this->Datagrid->ignoreFields(array('password'));
if($error = $this->session->flashdata('form_error')){
echo "$error";
}
echo form_open('test/proc');
echo $this->Datagrid->generate();
echo Datagrid::createButton('delete','Delete');
echo form_close();
}
function proc($request_type = ''){
$this->load->helper('url');
if($action = Datagrid::getPostAction()){
$error = "";
switch($action){
case 'delete' :
if(!$this->Datagrid->deletePostSelection()){
$error = 'Items could not be deleted';
}
break;
}
if($request_type!='ajax'){
$this->load->library('session');
$this->session->set_flashdata('form_error',$error);
redirect('test/index');
} else {
echo json_encode(array('error' => $error));
}
} else {
die("Bad Request");
}
}
}
?>
function __construct(){
parent::__construct();
$this->load->helper(array('datagrid','url'));
$this->Datagrid = new Datagrid('users','id');
}
function index(){
$this->load->helper('form');
$this->load->library('session');
$this->Datagrid->hidePkCol(true);
$this->Datagrid->setHeadings(array('email'=>'E-mail'));
$this->Datagrid->ignoreFields(array('password'));
if($error = $this->session->flashdata('form_error')){
echo "$error";
}
echo form_open('test/proc');
echo $this->Datagrid->generate();
echo Datagrid::createButton('delete','Delete');
echo form_close();
}
function proc($request_type = ''){
$this->load->helper('url');
if($action = Datagrid::getPostAction()){
$error = "";
switch($action){
case 'delete' :
if(!$this->Datagrid->deletePostSelection()){
$error = 'Items could not be deleted';
}
break;
}
if($request_type!='ajax'){
$this->load->library('session');
$this->session->set_flashdata('form_error',$error);
redirect('test/index');
} else {
echo json_encode(array('error' => $error));
}
} else {
die("Bad Request");
}
}
}
?>
