I'd like to get the security zone (Internet zone / local intranet) for a number of URL's which are in the same domain. I thought the best solution would be to get this through iFrame. I know that the statement value[i] = frames[i].isTrustedIE(); is not possible! So could you give me the missing puzzle to get working this? . Thank you very much . Here is the following code!

Code:
<html>
<head>
<script type="text/javascript">

function isTrustedIE(){
try{
    new ActiveXObject("Scripting.FileSystemObject");
}
catch(e){
    return false; //untrusted
}

return true; //trusted
}

function getZone() {

    var value = new Array();
    var text = new Array();
    var frameNames = document.getElementsByClass('iframeNames');

     for(var i = 0; i < frameNames.length; i++) {

         value[i] = frames[i].isTrustedIE();

            if(value[i] == true) {

                text[i] = "Trusted (Local Intranet)";

            }else {
                text[i] =  "Untrusted (Internet Zone)";
                               }


        } //end for


var showText = getElementsByClass("zone");
for(var i = 0; i < showText.length; i++) {
    setText(showText[i], text[i]);
};


    } //end getZone()


function setText(showText, text) {


    showText.innerHTML = text; 

    } //end setText


if(document.getElementsByClassName) {

    getElementsByClass = function(classList, node) {    
            return (node || document).getElementsByClassName(classList);
        };

}


</script>

</head>


<style type="text/css">

tr:nth-child(2n) {
background-color: #ddd;
}

.format {background-color: #ffff;}

#formatierung {
margin-left: 10px;
margin-top: 30px;
font-family: Arial;
font-size: 13px;

}

</style>

<body>

<iframe src = "http://example.com" class = "iframeNames" width = "0"

<iframe src = "http://example.com/index/" class = "iframeNames" width = "0"

<script type = "text/javascript">
