function creat_Object() { 
var xmlhttp; 
if (!xmlhttp && typeof XMLHttpRequest != 'undefined') { 
try { 
xmlhttp = new XMLHttpRequest(); 
} 
catch (e) { 
alert("Your browser is not supporting XMLHTTPRequest"); <BR> xmlhttp = false;

else { 
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); 
} 
return xmlhttp; 
} 
var request = creat_Object(); 
function sever_interaction() { 
if (request.readyState == 1) { 
document.getElementById('aja_cnts').value = ''; 
document.getElementById('aja_cnts').value = 'Loading...'; 
} 
if (request.readyState == 4) { 
var answer = request.responseText; 
document.getElementById('aja_cnts').value = ''; 
document.getElementById('aja_cnts').value = answer; 
} 
} 
function call_server() { 
request.open("GET", "Response.asp"); 
request.onreadystatechange = sever_interaction; request.send(''); 
} 
</script> 
<body> 
<input type="button" name="btnLoad" id="btnLoad" value="点击加载" onclick="call_server();" /> 
<input type="text" style=" width:265px; height:68px;" id="aja_cnts" /> 
</body> 
</html>

获取页面Response.asp代码：document.getElementById('aja_cnts').value
Response.asp代码示例：

<% 
Response.Write "您好！欢迎光临悠9小店！" 
Response.Write "我们的网址是：http://you9luck.taobao.com" 
%>
