关于ajax中在javascript的构造httpRequest的问题

Question

<script type="text/javascript">
        function getUserList() {
            var httpRequest;
            if (window.ActiveXObject) {
                httpRequest = new ActiveXObject("Microsoft.XMLDOM");
            } else {
                httpRequest = new XMLHttpRequest();
            }
            var url = "handler.ashx";
            httpRequest.open("POST", url, true);  //程序运行到这里就报错说  此对象不支持此属性或者用法
            httpRequest.send(null);
            httpRequest.onreadystatechange = function () {
                if (httpRequest.readyState == 4) {
                    alert(httpRequest.readyState + "      " + httpRequest.status);
                    if (httpRequest.status == 200) {
                        var dom = httpRequest.responseXML;
                        document.getElementById("one").innerHTML = dom.getElementsByTagName[0].text;
                        document.getElementById("two").innerHTML = dom.getElementsByTagName[1].text;
                        document.getElementById("three").innerHTML = dom.getElementsByTagName[2].text;
                        document.getElementById("four").innerHTML = dom.getElementsByTagName[3].text;
                        document.getElementById("five").innerHTML = dom.getElementsByTagName[4].text;
                    }
                }
            };
            
        };
    </script>求大牛们指点，好纠结啊。

Answer 1

顺便说一下，我的handler.ashx 组建成xml文件的，现在我就是想通过ajax来接收返回的xml文件，并输出来
