js獲取客戶端mac地址的方法

function getmac() {
              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;
                  return mac;
              }
