代碼如下:

<script type="text/javascript"><!--
var xmlHttp = null;//XmlHttp對(duì)象,Ajax核心
//創(chuàng)建一個(gè)Xml文檔,向服務(wù)器發(fā)送.
function f(){
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.3.0");//1創(chuàng)建xml對(duì)象,Active控件.
xmlDoc.async = false;//設(shè)置異步還是非異步

//向服務(wù)器發(fā)送Xml文檔
function sendXml(xmlDoc,serverURL){

var strDoc;
if (typeof(xmlDoc) == "object")//判斷,這里是object
strDoc = xmlDoc.xml;
else
strDoc = xmlDoc;
xmlHttp.open ("POST","Default.aspx" ,true);//第三個(gè)參數(shù)如果為真,則調(diào)用onreadystatechange屬性指定的回調(diào)函數(shù)。
xmlHttp.onreadystatechange=getData;
xmlHttp.send(strDoc);//向服務(wù)器發(fā)傳的數(shù)據(jù).
}
function getData(){
if (xmlHttp.readyState==4) //狀態(tài)為4表示完成.
{
var strxml=xmlHttp.responseText;//取得返回的Xml
alert(strxml);
}
}

<body>
<input type="button" onclick="f();" value="request" />

Ajax Server：
代碼如下:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Xml;
public partial class testXml_Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(Request.InputStream);//接收到客戶端傳來(lái)的xml
XmlNode rootnode = xmldoc.DocumentElement;
XmlNode pwd = rootnode.SelectSingleNode("pwd");
pwd.InnerText = "changed";//服務(wù)器端改變xml文檔內(nèi)容
Response.Write(xmldoc.InnerXml);//返回修改后的Xml文檔
Response.End();
}
}
