客户端获取MAC地址，到服务器验证
1， 网上找到的文章，用来获取客户端MAC,IP,主机名
<HTML>
<HEAD>
<TITLE>WMI Scripting HTML</TITLE>
<META http-equiv=Content-Type content="text/html; charset=gb2312">
<SCRIPT language=JScript event="OnCompleted(hResult,pErrorObject, pAsyncContext)" for=foo>
document.forms[0].txtMACAddr.value=unescape(MACAddr);
document.forms[0].txtIPAddr.value=unescape(IPAddr);
document.forms[0].txtDNSName.value=unescape(sDNSName);
</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>
<META content="MSHTML 6.00.2800.1106" name=GENERATOR>
</HEAD>
<BODY>
<OBJECT id=locator 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 = locator.ConnectServer();
var MACAddr ;
var IPAddr ;
var DomainAddr;
var sDNSName;
service.Security_.ImpersonationLevel=3;
service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');
</SCRIPT>
<FORM id=formfoo name=formbar action=NICPost.asp method=post>
<INPUT value=00:05:5D:0E:C7:FA name=txtMACAddr>
<INPUT value=192.168.0.2 name=txtIPAddr>
<INPUT value=typ name=txtDNSName> </FORM>
</BODY>
</HTML>
这样就能获得客户端主机的MAC。
2，控件的的 Visible 属性
前端我用textbox 获取MAC地址的值，然后传给后台，但是我不能让客户端看到控件，所以我设置了textBox1.Visible="false"，这样客户端就看到不控件，但是后台也无法取值。
所以用hidenFile控件，就能解决，客户端看不到控件，后台直接用hidenFile1.value 就能取到它的值。
