    php与ajax技术

    web2.0的到来,ajax逐渐成为主流,什么是ajax,ajax的开发模式,优点,使用技术。(ajax概述,ajax使用的技术,需要注意的 问题,在PHP应用ajax技术的应用)

    什么是ajax,ajax的开发模式,优点。

    ajax是由jesse james garrett创建的,是asynchronous javascript and xml,异步javascript和xml技术,ajax并不是一门新的语言或技术,它是javascript,xml,css,dom等多种技术的组合,可以实现客户端的异步请求操作,可以在不刷新页面下与服务器进行通信,从而减少了用户的等待时间。

    ajax开发模式:
    浏览器(客户端) http传输,http请求, web服务器 数据存储,后端处理,继承系统,服务器端。

    客户端(浏览器)JavaScript调用,ajax引擎 http请求,http传输, web和xml服务器,数据存储,后端处理,继承系统(服务端)。

    优点:减轻服务器的负担,可以把部分由服务器负担的工作转移到客户端上,无刷新更新页面,可以调用xml等外部数据,基于标准化的并被广泛支持的技术。

    JavaScript是一种在web页面中添加动态脚本代码的解释性程序语言。

    xmlhttprequest

    ie浏览器把xmlhttp

    var http_request = new ActiveXObject("Msxml2.XMLHTTP");
    
    var http_request = new ActiveXObject("Microsoft.XMLHTTP");
    

    mozailla,safari等其他浏览器

    var http_request = new XMLHttpRequest();
    
    if(window.XMLHttpRequest){
    http_request = new XMLHttpRequest();
    }else if(window.ActiveXObject){
     try{
     http_request = new ActiveXObject("Msxml2.XMLHTTP");
     }catch(e){
     try{
     http_request = new ActiveXObject("Msxml2.XMLHTTP");
    }catch(e){
     try{
     http_request = new ActiveXObject("Microsoft.XMLHTTP");
    }catch(e){}
    }
    }
    

    XMLHttpRequest对象的常用方法:

    open()方法用于设置进行异步请求目标的url

    open("method", "url" [,asyncFlag [,"userName" [, "password"]]])
    

    send()方法用于向服务器发送请求

    send(content)
    

    setRequestHeader()方法

    setRequestHeader()方法为请求的http头设置值

    setRequestHeader("label","value")
    

    label用于指定http头,value用于指定http头设置值

    open()方法过后才能使用setRequestHeader()方法
    

    abort()方法
    abort()方法用于停止当前异步请求

    getAllResponseHeaders()方法
    getAllResponseHeaders()方法用于以字符串形式完整的http头信息。

    xmlhttpRequest对象常用的属性
    onreadystatechange 每个状态改变时都会触发这个事件处理器,通常会调用一个JavaScript函数。

    readyState 请求的状态:

    0 为未初始化
    1 为正在下载
    2 为已加载
    3 在交互中
    4 为完成
    

    responseText 服务器的响应,表示字符串

    responseXML 服务器的响应,表示xml

    status 返回服务器的http状态码
    statusText 返回http状态码对应的文本

    xml语言为可扩展的标记语言,提供了用于描述结构化数据的格式。xmlHttpRequest对象与服务器交换的数据,通常采用xml格式。

    dom为文档对象模型,为xml文档的解析定义了一组接口。

    在PHP中应用AJAX技术检测用户名

    <script language="javascript">
    var http_request = false;
    function createRequest(url) {
    	//初始化对象并发出XMLHttpRequest请求
    	http_request = false;
    	if (window.XMLHttpRequest) { 										//Mozilla等其他浏览器
    		http_request = new XMLHttpRequest();
    		if (http_request.overrideMimeType) {
    			http_request.overrideMimeType("text/xml");
    		}
    	} else if (window.ActiveXObject) { 								//IE浏览器
    		try {
    			http_request = new ActiveXObject("Msxml2.XMLHTTP");
    		} catch (e) {
    			try {
    				http_request = new ActiveXObject("Microsoft.XMLHTTP");
    		   } catch (e) {}
    		}
    	}
    	if (!http_request) {
    		alert("不能创建XMLHTTP实例!");
    		return false;
    	}
    	http_request.onreadystatechange = alertContents;   					 //指定响应方法
    	
    	http_request.open("GET", url, true);								 //发出HTTP请求
    	http_request.send(null);
    }
    function alertContents() {   											 //处理服务器返回的信息
    	if (http_request.readyState == 4) {
    		if (http_request.status == 200) {
    			alert(http_request.responseText);
    		} else {
    			alert('您请求的页面发现错误');
    		}
    	}
    }
    </script>
    <script language="javascript">
    function checkName() {
    	var username = form1.username.value;
    	if(username=="") {
    		window.alert("请填写用户名!");
    		form1.username.focus();
    		return false;
    	}
    	else {
    		createRequest('checkname.php?username='+username+'&nocache='+new Date().getTime());
    	}
    }
    </script>
    
    <?php
    	header('Content-type: text/html;charset=GB2312');		//指定发送数据的编码格式为GB2312
    	$link=mysql_connect("localhost","root","root");
    	mysql_select_db("db_database",$link);
    	$GB2312string=iconv( 'UTF-8', 'gb2312//IGNORE' , $RequestAjaxString);			//Ajax中先用encodeURIComponent对要提交的中文进行编码
    	mysql_query("set names gb2312");
    	$username=$_GET[username];
    	$sql=mysql_query("select * from tb_user where name='".$username."'");
    	$info=mysql_fetch_array($sql);
    	if ($info){
    		echo "很报歉!用户名[".$username."]已经被注册!";
    	}else{
    		echo "祝贺您!用户名[".$username."]没有被注册!";
    	}
    ?>
    

    类别添加

    <script language="javascript">
    var http_request = false;

    xml基础技术

    了解xml,使用simpleXML解析文档的方法
    遍历xml文档,修改,保存xml,创建xml文档的方法

    xml语法
    xml文档结构,xml声明,处理指令,注解,xml元素,xml属性,使用cdata标记,xml命令空间。

    XML文档结构

    <?xml version="1.0" encoding="gb2312" standalone="yes"?>
    
    <?xml-stylesheet type="text/css" href="111.css"?>
    

    XML声明

    <?xml version="1.0" encoding="gb2312" standalone="yes"?>
    

    image.png

    处理指令

    <?xml-stylesheet type = "text/css" href="111.css"?>
    
    <?处理指令名 处理执行信息?>
    

    xml-stylesheet:样式表单处理指令
    type="text/css":设定了文档所使用的样式是css
    href="111.css":设定了样式文件的地址

    XML属性

    <标签 属性名="属性值" 属性名=""…>内容</标签>

    SimpleXML
    创建SimpleXML对象
    Simplexml_load_file()函数,将指定的文件解析到内存中
    Simplexml_load_string()函数,将创建的字符串解析到内存当中
    Simplexml_load_date()函数,将一个使用dom函数创建的domDocument对象导入到内存当中

    遍历所有子元素
    children()方法和foreach循环语句可以遍历所有子节点元素

    遍历所有属性
    SimpleXML对象中的attributes()方法
