No you cannot get the MAC address in JavaScript, mainly because the MAC address uniquely identifies the running computer so it would be a security vulnerability.

Now if all you need is a unique identifier, I suggest you create one yourself using some cryptographic algorithm and store it in a cookie.

If you really need to know the MAC address of the computer AND you are developing for internal applications, then I suggest you use an external component to do that: ActiveX for IE, XPCOM for Firefox (installed as an extension).

Only IE,

 

<script language="javascript">
function showMacAddress(){

    var obj = new ActiveXObject("WbemScripting.SWbemLocator");
    var s = obj.ConnectServer(".");
    var properties = s.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration");
    var e = new Enumerator (properties);


    var output;
    output='<table border="0" cellPadding="5px" cellSpacing="1px" bgColor="#CCCCCC">';
    output=output + '<tr bgColor="#EAEAEA"><td>Caption</td><td>MACAddress</td></tr>';
    while(!e.atEnd())

    {
        e.moveNext();
        var p = e.item ();
        if(!p) continue;
        output=output + '<tr bgColor="#FFFFFF">';
        output=output + '<td>' + p.Caption; + '</td>';
        output=output + '<td>' + p.MACAddress + '</td>';
        output=output + '</tr>';
    }

    output=output + '</table>';
    document.getElementById("box").innerHTML=output;
}
</script>
