以下为JS获取几种URL地址的方法
thisURL = document.URL;
thisHREF = document.location.href;
thisSLoc = self.location.href;
thisDLoc = document.location;
thisTLoc = top.location.href;
thisPLoc = parent.document.location;
thisTHost = top.location.hostname;
thisHost = location.hostname;
tmpHPage = thisHREF.split( "/" );
thisHPage = tmpHPage[ tmpHPage.length-1 ];
tmpUPage = thisURL.split( "/" );
thisUPage = tmpUPage[ tmpUPage.length-1 ];
下面为使用JS获取MAC地址、IP地址及主机名的方法：
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
</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")
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>
