Ajax已经听说了很长时间了，一致没有使用，感觉应该是不错的。今天作了一个简单的测试，嘿嘿，还不错！
Ajax.js
// JavaScript Document
var xmlHttp;
var TagsId="body";
function CreateXmlHttp(){
if(window.ActiveXObject){
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
else if (window.XMLHTTPRequest){
xmlHttp=new XMLHTTPRequest();
}
}
function getTextXmlData(url){
CreateXmlHttp();
xmlHttp.onreadystatechange=HandleStateChanged;
xmlHttp.open("get",url,false); //第三个参数boolean asynch表示异步否
xmlHttp.send(null);
}
function HandleStateChanged(){
var msg;
if(xmlHttp.readyState==4){
if(xmlHttp.status==200){
msg=xmlHttp.responseText;
}
else{
msg="发生错误:<br/>错误状态 " + xmlHttp.status;
}
}else{
switch(xmlHttp.readystate)
{
case 0:
//对象已建立，但是尚未初始化（尚未调用open方法）
msg="初始化对象...";
break;
case 1:
//对象已建立，尚未调用send方法
msg="正在尝试服务器连接...";
break;
case 2:
//send方法已调用，但是当前的状态及http头未知
msg="服务器连接成功。";
break;
case 3:
//已接收部分数据
//因为响应及http头不全，
//这时通过responseBody和responseText获取部分数据会出现错误，
msg="";
break;
default:
msg="未知状态！";break;
}
}
document.getElementById(TagsId).innerHTML=msg;
}
