IP address client network card

复制代码代码如下:

 
<html> 
<head> 
<title></title> 
</head> 
<body> 
<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" && objObject.DNSServerSearchOrder!=null) 
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> 

代码是网上找到，但是经过修改。

原因是比如你笔记本有多张网卡，会出现获取你未联网或者禁用网卡的信息，解决办法：加限制条件：

objObject.DNSServerSearchOrder!=null

加上这个限制条件后，就能取到联网客户端的网卡IP地址了。

不过还有个问题就是只能限制IE浏览器，而且Activex必须要全部启用。
