WMI scripts are not running on Windows 8.1

Question

Hi, I am using the below JavaScript to get the client IP and mac address in my application:
function getIP() {
    var wmi = GetObject("winmgmts:{impersonationLevel=impersonate}");
    e = new Enumerator(wmi.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True"));
    for (; !e.atEnd(); e.moveNext()) {
        var s = e.item();
alert('Mac: ' + s.MACAddress + ' IP: ' + s.IPAddress(0));
 This java script is working fine on Windows XP/7/2008R2, but not on Windows 8.1.
On Windows 8.1, the below script throws error:
var wmi = GetObject("winmgmts:{impersonationLevel=impersonate}");
Line: 10
Error:'GetObject' is undefined 
I am using Lenovo ThinkPad to test this script, below are the system details:

Hi，
I am afraid GetObject function in JavaScript is not supported in IE9 or later, see:
GetObject Function (JavaScript):(This function is not supported in Internet Explorer 9 (standards mode) or later.)
And regarding the scripts modification, we'd better seek help in the scripting guys forum for a better assistance:
