我有一个在 Internet Explorer 上运行良好的源代码，但无法在 Chrome 或 Firefox 上运行。我想让它便携。请帮忙。

<html> 
  <head>
   <title>Login</title>

   <script language="javascript">

    function valUser(){

    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async = "false";
        xmlDoc.onreadystatechange = functory;
        xmlDoc.load("normal.xml");

    }

    function functory(){
        var u = document.forms[0].user.value;
        var p = document.forms[0].pwd.value;        

        if(xmlDoc.readyState == 4){

            xmlObj = xmlDoc.documentElement;
            var len = xmlObj.childNodes.length;

            for(i = 0; i < len; i++)
            {    
                var nodeElement = xmlObj.childNodes[i];
                var ux = nodeElement.childNodes[0].firstChild.nodeValue;
                var mx = nodeElement.childNodes[1].firstChild.nodeValue;
                var ex = nodeElement.childNodes[2].firstChild.nodeValue;
                var px = nodeElement.childNodes[3].firstChild.nodeValue;

                if((ux == u)&&(px == p)){
                userDetails(ux,mx,ex)
                }
                else {
                var divInvalid = document.getElementById('invalid');
                divInvalid.innerHTML = "<b>Invalid Username or password</b>";
                }
            }
        }

    }

function userDetails(u,m,e){
var newWindow = window.open("", "_self", "height=250,width=250,toolbar=yes,scrollbar=yes,status=yes");
var content = "<html><head><title>Intro</title></head><h1 align='center'><font face='Lucida Handwriting' color='red'>Welcome To GlenMark Pharma</h1></font>";
content += "<body>";
content += "<table align='center'border='1'><tr><th>ENAME</th><th>Mobile</th><th>Email</th></tr>";
content += "<tr><td>"+u+"</td><td>"+m+"</td><td>"+e+"</td></tr></table>";
content += "<div style='postion:absolute;top:10px;right:5px'><a href='logout.html'>LOgout</a></div>";
content += "</body></html>";

newWindow.document.write(content);
newWindow.blur();
}


   </script>
  </head>

  <body >  
   <div style="position:absolute;left:0px;top:0px;">
    <img src="login.jpg" height="650"></img>      

   <div style="font-family:Monotype Corsiva;position:absolute;left:640px;top:250px;"><h1><font color="0066FF">Employee Login</font></h1></div>
   </div>


  <form method="post" action="ret.html" name="frmGlenMark">

   <div style="position:absolute;left:640px;top:325px">
    <input type="text" name="user" size="25">
   </div>

   <div style="position:absolute;left:640px;top:355px">
    <input type="password" name="pwd" size="25">
   </div>

   <div style="position:absolute;left:640px;top:385px">
    <input type="Button" value="Login" onClick="valUser()">
   </div>


   <div id="invalid" style="position:absolute;left:640px;top:410px"></div>

<!--
   <div style="position:absolute;left:705px;top:385px">
    <input type="reset" name="Reset">
   </div>
-->


  </form>
  </body>

</html>

Uncaught ReferenceError: ActiveXObject is not defined --> 这是我得到的错误。

我尝试了以下方法使其可移植，但仍然出现错误。喜欢：

function valUser(){

    if(window.XMLHttpRequest)
    {
        xhttp = new XMLHttpRequest();

    }
    else
    {
          xhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }

        xhttp.open("GET","normal.xml",false);
        xhttp.send();
        xmlDoc=xhttp.responseXML;
        onreadystatechange = functory;

    }

未捕获的 TypeError：DOM 对象构造函数不能作为函数调用。
