无法在Windows 8上使用Javascript ActiveXObject检测客户端mac地址

Question

我试图在Windows 8上使用JavaScript ActiveXObject获得客户端mac地址，但它没有工作。

实际上，它在windows 7上运行得很好。

这是我的密码：

var obj = new ActiveXObject("WbemScripting.SWbemLocator");
var s = obj.ConnectServer(".");
var properties = s.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration");
var e = new Enumerator(properties);
var output;
var outputTemp = "";
var Number6MacAddress = "";
var ReturnedMACAddresesses = "";
output = '<table border="0" cellPadding="5px" cellSpacing="1px" bgColor="#CCCCCC">';
outputTemp = '';
output = output + '<tr bgColor="#EAEAEA"><td>Caption</td><td>MACAddress</td></tr>';
var Counter = 0;
while (!e.atEnd()) {
  e.moveNext();
  var p = e.item();
  if (!p) continue;
  output = output + '<tr bgColor="#FFFFFF">';
  output = output + '<td>' + p.Caption; +'</td>';
  output = output + '<td>' + p.MACAddress + '</td>';
  //output = output + '<td>' + p.Properties_[43].Value + '</td>';
  output = output + '</tr>';
}

在Windows7中，给出了以下结果：

注意到ID 00000007成功地检测到网卡MACAddress，这就是我正在使用的.

Caption MACAddress 
[00000001] WAN Miniport (IKEv2) null 
[00000002] WAN Miniport (L2TP) null 
[00000003] WAN Miniport (PPTP) null 
[00000004] WAN Miniport (PPPOE) null 
[00000005] WAN Miniport (IPv6) null 
[00000006] WAN Miniport (Network Monitor) null 
[00000007] Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20) 50:E5:49:FC:4D:3F 
[00000008] WAN Miniport (IP) null 
[00000009] Microsoft ISATAP Adapter null 
[00000010] RAS Async Adapter null 
[00000011] Microsoft Teredo Tunneling Adapter null 
[00000012] Remote NDIS based Internet Sharing Device null 
[00000013] Microsoft ISATAP Adapter null 

​

，但在Windows8上，它给出了以下结果：

通知:我的网卡不在名单上？我不知道为什么？

​

Caption  -  MACAddress 

[00000001] - Microsoft Kernel Debug Network Adapter null 

[00000002] - Microsoft ISATAP Adapter null 

[00000003] - Microsoft Teredo Tunneling Adapter null

有什么想法吗？

您的代码正在跳过查询的第一个结果(即通常ID为00000000的第一个网络接口)，这可能是您的Windows8框中唯一有MAC地址的。

将e.moveNext()移到循环的末尾，看看它现在是否显示：

var obj = new ActiveXObject("WbemScripting.SWbemLocator");
var s = obj.ConnectServer(".");
var properties = s.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration");
var e = new Enumerator(properties);
var output = '<table border="0" cellPadding="5px" cellSpacing="1px" bgColor="#CCCCCC">';
output = output + '<tr bgColor="#EAEAEA"><td>Caption</td><td>MACAddress</td></tr>';
while (!e.atEnd()) {
  var p = e.item();
  if (!p) continue;
  output = output + '<tr bgColor="#FFFFFF">';
  output = output + '<td>' + p.Caption; +'</td>';
  output = output + '<td>' + p.MACAddress + '</td>';
  output = output + '</tr>';
  e.moveNext();
}
output = output + '</table>';
