最近遇到一个需求，医院要求呼叫中心账号必须对应MAC地址，也就是说该MAC地址必须和呼叫中心账号对应才可使用，这可就难道我了，这需求就要求每次都判断用户登录的电脑MAC地址是否有呼叫中心账号，当然只针对IE浏览器，毕竟其他浏览器是直接就给禁止此功能的。
那么首先问题一：如何才能通过页面访问得到本地MAC地址
问题二：每台电脑上都有多个MAC地址，那么应该选用哪一个MAC地址
MAC地址是每台电脑链接网络的物理地址，是唯一标识，想要从浏览器获取电脑的信息，那么就需要ActiveX,所以其他浏览器是没有办法通过js获取MAC地址的。
方法一：（推荐）需要客户端设置将服务器地址加入受信任站点

<object classid="CLSID:76A64158-CB41-11D1-8B02-00600806D9B6" id="locator" style="display:none;visibility:hidden"></object>
<object classid="CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223" id="foo" style="display:none;visibility:hidden"></object>
<form name="myForm">
<br/>MAC地址：<input type="text" name="macAddress">
<br/>IP地址：<input type="text" name="ipAddress">
<br/>主机名：<input type="text" name="hostName">
</form>
</body>
</html>
<script language="javascript">
var sMacAddr="";
var sIPAddr="";
var sDNSName="";
var service = locator.ConnectServer();
service.Security_.ImpersonationLevel=3;
service.InstancesOfAsync(foo, ‘Win32_NetworkAdapterConfiguration‘);
</script>
<script FOR="foo" EVENT="OnObjectReady(objObject,objAsyncContext)" LANGUAGE="JScript">
if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true){
if(objObject.IPEnabled && objObject.IPAddress(0) !=null && objObject.IPAddress(0) != "undefined")
sIPAddr = objObject.IPAddress(0);
if(objObject.MACAddress != null &&objObject.MACAddress != "undefined")
sMacAddr = objObject.MACAddress;
if(objObject.DNSHostName != null &&objObject.DNSHostName != "undefined")
sDNSName = objObject.DNSHostName;
}
</script>
<script FOR="foo" EVENT="OnCompleted(hResult,pErrorObject, pAsyncContext)" LANGUAGE="JScript">
myForm.macAddress.value=sMacAddr;
myForm.ipAddress.value=sIPAddr;
myForm.hostName.value=sDNSName;
</script>
