js擷取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);            }        } 

還有其它方法：

<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>
