var request; 
function sendData() 
{
    var url = "default.aspx";
    request = new ActiveXObject("Microsoft.XMLHTTP");
    request.onreadystatechange = handleResponse;
    request.open("POST", "response.aspx", true);
}
function handleResponse() {
    if (request.readyState == 4) {
        if (request.status == 200) {
            alert(request.responseText);
        }
     }
}

错误第九行 字符5 request 对象没定义

[hoojo]

request.send();//没有发送请求

你用那个浏览器？你的代码只有IE能运行。

如果用的是IE有可能没正确创建xhr对象
