获取客户端IP。
<HTML> <HEAD> <TITLE>GetLocalIP</TITLE> </HEAD> <BODY> 获取IP: <script language="JavaScript"> function GetLocalIPAddr(){ var oSetting = null; var ip = null; try{ oSetting = new ActiveXObject("rcbdyctl.Setting"); ip = oSetting.GetIPAddress; if (ip.length == 0){ return "没有连接到Internet"; } oSetting = null; }catch(e){ return ip; } return ip; } document.write(GetLocalIPAddr()+"<br/>") </script> </BODY> </HTML>
获取客户端处在网络中的IP，前提是客户得联网。
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <title>JavaScript获取客户端IP[利用新浪接口]</title> </head> <body> <script type="text/javascript" src="http://counter.sina.com.cn/ip/" charset="gb2312"></script> <!--获取接口数据，注意charset --> <script type="text/javascript"> document.writeln("IP地址："+ILData[0]+"<br />"); //输出接口数据中的IP地址 document.writeln("地址类型："+ILData[1]+"<br />"); //输出接口数据中的IP地址的类型 document.writeln("地址类型："+ILData[2]+"<br />"); //输出接口数据中的IP地址的省市 document.writeln("地址类型："+ILData[3]+"<br />"); //输出接口数据中的IP地址的 document.writeln("地址类型："+ILData[4]+"<br />"); //输出接口数据中的IP地址的运营商 </script> </body> </html>
调用VBS脚本，获取计算机名（有些人不知道什么是计算机名，简单解释就是它是这台机器的物理名称而不是你在用的那个用户名）和登录的用户名。
<HTML> <HEAD> <TITLE>WMI Scripting HTML</TITLE> </HEAD> <BODY> <script language=javascript> var WshShell =new ActiveXObject("WScript.Shell"); document.write("计算机名 = "+ WshShell.ExpandEnvironmentStrings("%COMPUTERNAME%")+"<br/>"); document.write("登录用户名 = "+ WshShell.ExpandEnvironmentStrings("%USERNAME%")+"<br/>"); </script> </BODY> </HTML>
获取计算机名、登录的用户名和域名（如果你加入了域，显示你这台机器处在哪个域中）。
<HTML> <HEAD> <TITLE>WMI Scripting HTML</TITLE> </HEAD> <BODY> <script language=javascript> var wshNetwork = new ActiveXObject("WScript.Network"); document.write("域名 = "+ wshNetwork.UserDomain+"<br/>"); document.write("计算机名 = "+ wshNetwork.ComputerName+"<br/>"); document.write("登录用户名 = "+ wshNetwork.UserName+"<br/>"); </script> </BODY> </HTML>
能够获取到局域网IP地址，本机的MAC，以及机器名（代码来源网络）。
<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") 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>
