Zend Framework框架中实现Ajax的方法示例

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'); require_once 'Zend/Controller/Front.php'; require_once 'Zend/Controller/Router/Route.php'; $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 require_once 'Zend/Db.php'; require_once 'Zend/Registry.php'; class TestDbCon{ public static function getTestDbCon(){ $params=array( 'host'=>'localhost', 'username'=>'root', 'password'=>'123456', 'dbname'=>'test' ); $con=Zend_Db::factory('Pdo_Mysql',$params); return $con; } } ?>

3.News.php //抽象出来的数据库表文件

<?php /** * PHP Template. */ require_once 'Zend/Db/Table/Abstract.php'; class News extends Zend_Db_Table_Abstract{ // protected $_schema='test'; protected $_name='news'; protected $_primary='id'; protected $_sequence=true; } ?>

4.TestController.php //控制器

<?php require_once 'Zend/Controller/Action.php'; require_once 'Zend/View.php'; require_once 'News.php'; require_once 'TestDbCon.php'; class TestController extends Zend_Controller_Action{ public function ajaxAction(){ $this->render(); } public function getAjaxAction(){ // $aaa=$_GET['q']; // $this->view->sid=$_GET['sid']; $aaa=$this->_request->getParam('q'); $this->view->sid=$this->_request->getParam('sid'); $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 showValue(str) { xmlHttp=getXmlHttpObject(); if (xmlHttp==null) { alert ("您的浏览器不支持AJAX."); return; } var url="/test/get-ajax"; url=url+"/q/"+str; url=url+"/sid/"+Math.random(); xmlHttp.onreadystatechange=stateChanged; xmlHttp.open("GET",url,true); xmlHttp.send(null); } function stateChanged() { if (xmlHttp.readyState==4) { document.getElementById("resulte").innerHTML=xmlHttp.responseText; } } function getXmlHttpObject() { var xmlHttp=null; try { // Firefox, Opera 8.0+, Safari xmlHttp=new XMLHttpRequest(); } catch (e) { // Internet Explorer try { xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { xmlHttp=new ActiveXObject("Microsoft.XMLHTTP"); } } return xmlHttp; } </script> <form> 请选择一位客户: <select onchange="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><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; ?>
