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