JS获取计算机mac地址以及IP的实现方法

       <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>
      <SCRIPT  language=JScript>
      var  service  =  locator.ConnectServer();
      var  MACAddr  ;
      var  IPAddr  ;
      var  DomainAddr;

      service.Security_.ImpersonationLevel=3;
      service.InstancesOfAsync(foo,  "Win32_NetworkAdapterConfiguration");

      </SCRIPT>       <SCRIPT  language=JScript  event="OnCompleted(hResult,pErrorObject,  pAsyncContext)"  for=foo>
  alert("物理地址"+MACAddr+"IP地址"+IPAddr+"主机名"+sDNSName))
      </SCRIPT>"
