本文主要是介绍在Zend Framework 中实现Ajax,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
开发平台:Windows XP SP2
测试平台:FreeBSD 7.0
开发工具:Netbeans 6.1
使用框架:Zend Framework 1.5.2
数据库: MySQL 5.0.51a
****************************************
所需的数据库表和ZF相关目录以及文件:
一、表:
mysql> select * from news;
+----+-------+---------------------+
| id | title | add_time
| +----+-------+---------------------+
| 22 | rot | 2008-01-04 00:00:00 |
| 23 | aaa | 2008-01-04 00:00:00 |
| 24 | rot | 2008-01-04 00:00:00 |
| 29 | dfeew | 2008-02-27 00:00:00 |
| 26 | jesse | 2008-02-27 00:00:00 |
| 27 | andle | 2008-02-27 00:00:00 |
| 28 | andle | 2008-02-27 00:00:00 |
+----+-------+---------------------+
二、目录:
三、相关文件:
1.index.php //入口文件
2.TestDbCon.phhp //数据库连接文件
3.News.php //抽象出来的数据库表文件
4.TestController.php //控制器
5.ajax.phtml //客户操作页面,包含生成XMLHttpRequest对象,发ajax请求,处理请求,取回服务器返回值等
6.get-ajax.phtml //最后根据由服务器取回的数据生成页面元素
**********************************************
相关文件内容:
1.index.php //入口文件<?php
set_include_path('.' . PATH_SEPARATOR .'../library' . PATH_SEPARATOR . get_include_path() . PATH_SEPARATOR . '../application/modules/default/models' . PATH_SEPARATOR . '../application/modules/admin/models');

$ctrl=Zend_Controller_Front::getInstance();
$ctrl->addModuleDirectory('../application/modules');
$ctrl->throwExceptions(true);
$ctrl->dispatch();
?>
2.TestDbCon.phhp //数据库连接文件
<?php

$conn=TestDbCon::getTestDbCon();
$news_tb=new News(array('db'=>$conn));
$where=$news_tb->getAdapter()->quoteInto('title=?',$aaa);
$this->view->rowSet=$news_tb->fetchAll($where);
$this->render();

}
?>
5.ajax.phtml //客户操作页面,包含生成XMLHttpRequest对象,发ajax请求,处理请求,取回服务器返回值等
<script type="text/javascript">
var xmlHttp

function getXmlHttpObject()
{
var xmlHttp=null;

// Internet Explorer

</script>
<form>
请选择一位客户:
<select name="customers" οnchange="showValue(this.value)">
<option value="rot">rot</option>
<option value="aaa">aaa</option>
<option value="jesse">jesse</option>
<option value="andle">andle</option>
</select>
</form>
<p>
<div id="resulte"><b>客户信息将在此处列出。</b></div>
</p>
6.get-ajax.phtml //最后根据由服务器取回的数据生成页面元素
<?php
foreach($this->rowSet as $row){
echo "<div>";
echo "<ul>";
echo "<li>";
echo "id=".$row->id." title=".$row->title." add_time=".$row->add_time;
echo "</li>";
echo "</ul>";
echo "</div>";
}
echo $this->sid;
?>
