Cannot detect client mac address using Javascript ActiveXObject On Windows 8

Question

I am trying to get client mac address using JavaScript ActiveXObject On Windows 8 but it didn't work.

actually it works fine on windows 7.

Here is My Code:

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;
var outputTemp = "";
var Number6MacAddress = "";
var ReturnedMACAddresesses = "";
output = '<table border="0" cellPadding="5px" cellSpacing="1px" bgColor="#CCCCCC">';
outputTemp = '';
output = output + '<tr bgColor="#EAEAEA"><td>Caption</td><td>MACAddress</td></tr>';
var Counter = 0;
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 + '<td>' + p.Properties_[43].Value + '</td>';
  output = output + '</tr>';
}

In Windows 7 it gives the following result:

Notice That ID [00000007] detected Network card MACAddress Successfully and this what i am using.

 Caption MACAddress [00000001] WAN Miniport (IKEv2) null [00000002] WAN Miniport (L2TP) null [00000003] WAN Miniport (PPTP) null [00000004] WAN Miniport (PPPOE) null [00000005] WAN Miniport (IPv6) null [00000006] WAN Miniport (Network Monitor) null [00000007] Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20) 50:E5:49:FC:4D:3F [00000008] WAN Miniport (IP) null [00000009] Microsoft ISATAP Adapter null [00000010] RAS Async Adapter null [00000011] Microsoft Teredo Tunneling Adapter null [00000012] Remote NDIS based Internet Sharing Device null [00000013] Microsoft ISATAP Adapter null 

But on Windows 8 it gives me the following result

NOTICE: My Network Card is not on the list? I don't know why?

 Caption - MACAddress [00000001] - Microsoft Kernel Debug Network Adapter null [00000002] - Microsoft ISATAP Adapter null [00000003] - Microsoft Teredo Tunneling Adapter null 

any ideas?

Answer 1

Your code is skipping the first result of the query (that is, the first network interface, with ID 00000000 normally) which might happen to be the only one with a MAC address on your Windows 8 box.

Move the e.moveNext() to the end of the loop and see if it shows now:

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