当前在Web开发中，jQuery和PHP无疑是绝佳的配合。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 " );
}
}
}
