用法和asp下面是一样的：
A页面:
<script language="javascript">
<!--
function Test()
{
//创建ActiveXObject
try {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
xmlHttp = new XMLHttpRequest();
}

xmlHttp.onreadystatechange = function() {
if (xmlHttp.readyState == 4) {
if (xmlHttp.status == 200) {
var data = xmlHttp.responseText;
document.getElementById("TextBox1").value = data;
}
}
}

xmlHttp.open("GET","B.aspx?strID=1");
xmlHttp.send(null);
}
-->
</script>

B页面：
private void Page_Load(object sender, System.EventArgs e)
{
string strID = "";

if (Request.QueryString.Keys.Count > 0 && Request.QueryString["strID"].Length > 0)
{
strID = Request.QueryString["strID"].ToString();
}

//你自己的运算

Response.Write("处理结果");
//完成并马上关闭。以免传入多余的数据。
Response.Flush();
Response.Close();
}
