js获取mac地址

function MacInfo() {
            var locator = new ActiveXObject("WbemScripting.SWbemLocator");
            var service = locator.ConnectServer(".");
            var properties = service.ExecQuery("Select * from Win32_NetworkAdapterConfiguration Where IPEnabled =True");
            var e = new Enumerator(properties);
            {
                var p = e.item();
                var mac = p.MACAddress;
                document.getElementById("<%=hd_macAddress.ClientID %>").value = unescape(mac);
            }
        }

还有其它方法:

<SCRIPT language=JScript event="OnCompleted(hResult,pErrorObject, pAsyncContext)" for=foo>
        document.getElementById("txtMACAddr").value=unescape(MACAddr);
        document.getElementById("txtIPAddr").value=unescape(IPAddr);
        document.getElementById("txtDNSName").value=unescape(sDNSName);
        //document.formbar.submit();
    </SCRIPT>
    <SCRIPT language=JScript event=OnObjectReady(objObject,objAsyncContext) for=foo>
    if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true)
    {
        if(objObject.MACAddress != null && objObject.MACAddress != "undefined")
        MACAddr = objObject.MACAddress;
        if(objObject.IPEnabled && objObject.IPAddress(0) != null && objObject.IPAddress(0) != "undefined")
        IPAddr = objObject.IPAddress(0);
        if(objObject.DNSHostName != null && objObject.DNSHostName != "undefined")
        sDNSName = objObject.DNSHostName;
    }
    </SCRIPT>

<OBJECT id="fool" classid="CLSID:76A64158-CB41-11D1-8B02-00600806D9B6" VIEWASTEXT></OBJECT>
    <OBJECT id="foo" classid="CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223"></OBJECT>
    <SCRIPT language=JScript>
        var service = fool.ConnectServer();
        var MACAddr;
        var IPAddr;
        var DomainAddr;
        var sDNSName;
        service.Security_.ImpersonationLevel = 3;
        service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');
    </SCRIPT>
