Ajax 和 Asp 的編程

ajax.html 複製代碼 代碼如下:<script>
function f(){
var req =new ActiveXObject("Microsoft.XMLHTTP");
req.open("GET","t.asp?t1="+t1.value, true);
req.onreadystatechange = function(){
　 if (req.readyState == 4) {
　 if (req.status == 200) {
　　 msg.innerText = req.responseXML.documentElement.tagName;
}
}
}
req.send(null);
}
</script>
<div>1：顯示"OK"; 其他字元:顯示"Error"</div>
<input id=t1 value=1>
<input type=button value="檢測" onclick="javascript:f()"> <a href="javascript:f()">檢測</a>
<div id=msg></div>

t.asp複製代碼 代碼如下:<%
Response.ContentType="text/xml"
response.charset="gb2312"
if request.querystring("t1")="1" then
response.write("<OK/>")
else
response.write("<ERROR/>")
end if
%>
