本文实例讲述了Zend Framework框架中实现Ajax的方法。分享给大家供大家参考,具体如下:
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

<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 name= "customers" 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 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
希望本文所述对大家基
- <?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;
- ?>
于Zend Framework框架的PHP程序设计有所帮助。
