Use the ActiveX Object to Get MAC Address in JavaScript
To enable the ActiveX object, we will go to Tools and select Internet Options. Then on the Security tab, we will click on Custom Level.
We will go down until we see Initialize and the script ActiveX controls not marked as safe. We will enable it, then click Ok.
<script type="text/javascript">
var macAddress = "";
var computerName = "";
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();
macAddress = s.MACAddress;
computerName = s.DNSHostName;
}
