JavaScript获取客户端计算机硬件及系统等信息的方法

JavaScript 获取客户端计算机硬件及系统信息 
通过WMI来实现获取客户端计算机硬件及系统信息: 

function getSysInfo(){ var locator = new ActiveXObject ("WbemScripting.SWbemLocator"); var service = locator.ConnectServer("."); //CPU信息 var cpu = new Enumerator (service.ExecQuery("SELECT * FROM Win32_Processor")).item(); var cpuType=cpu.Name,hostName=cpu.SystemName; //内存信息 var memory = new Enumerator (service.ExecQuery("SELECT * FROM Win32_PhysicalMemory")); for (var mem=[],i=0;!memory.atEnd();memory.moveNext()) mem[i++]={cap:memory.item().Capacity/1024/1024,speed:memory.item().Speed} //系统信息 var system=new Enumerator (service.ExecQuery("SELECT * FROM Win32_ComputerSystem")).item(); var physicMenCap=Math.ceil(system.TotalPhysicalMemory/1024/1024),curUser=system.UserName,cpuCount=system.NumberOfProcessors return {cpuType:cpuType,cpuCount:cpuCount,hostName:hostName,curUser:curUser,memCap:physicMenCap,mem:mem} } 

代码实现主要包括这几部分: 

先通过new ActiveXObject ("WbemScripting.SWbemLocator"); 访问到WbemScripting对象。 
通过locator.ConnectServer(".");连接我们本地电脑(.代表本地电脑,当然 
也可以访问其他计算机)。 
通过service.ExecQuery("SELECT * FROM Win32_Processor")这个类似sql的语句(其实系统信息也是存储在计算中一个类似数据库的文件中)获取我们需要的对象的记录集。 
通过new Enumerator来创建一个可枚举的对象,下面就可以遍历取信息了。 

注意:运行的前提是要修改浏览器安全设置,“允许对未标记为可安全执行的ActiveX 
脚本的运行”。 
这里主要取了CPU、内存及系统用户几个信息,大家利用WMI的API或者借助JSEDIT获取 
到更多的信息。下面列出了常用信息的类:

示例: 

function button1_onclick() {//cpu 信息 var locator = new ActiveXObject ("WbemScripting.SWbemLocator"); var service = locator.ConnectServer("."); var properties = service.ExecQuery("SELECT * FROM Win32_Processor"); var e = new Enumerator (properties); document.write("<table border=1>"); for (;!e.atEnd();e.moveNext ()) { var p = e.item (); document.write("<tr>"); document.write("<td>" + p.Caption + "</td>"); document.write("<td>" + p.DeviceID + "</td>"); document.write("<td>" + p.Name + "</td>"); document.write("<td>" + p.CpuStatus + "</td>"); document.write("<td>" + p.Availability + "</td>"); document.write("<td>" + p.Level + "</td>"); document.write("<td>" + p.ProcessorID + "</td>"); document.write("<td>" + p.SystemName + "</td>"); document.write("<td>" + p.ProcessorType + "</td>"); document.write("</tr>"); } document.write("</table>"); } function Button2_onclick() {//CD-ROM 信息 var locator = new ActiveXObject ("WbemScripting.SWbemLocator"); var service = locator.ConnectServer("."); var properties = service.ExecQuery("SELECT * FROM Win32_CDROMDrive"); var e = new Enumerator (properties); document.write("<table border=1>"); for (;!e.atEnd();e.moveNext ()) { var p = e.item (); document.write("<tr>"); document.write("<td>" + p.Caption + "</td>"); document.write("<td>" + p.Description + "</td>"); document.write("<td>" + p.Drive + "</td>"); document.write("<td>" + p.Status + "</td>"); document.write("<td>" + p.MediaLoaded + "</td>"); document.write("</tr>"); } document.write("</table>"); } function Button3_onclick() {//键盘信息 var locator = new ActiveXObject ("WbemScripting.SWbemLocator"); var service = locator.ConnectServer("."); var properties = service.ExecQuery("SELECT * FROM Win32_Keyboard"); var e = new Enumerator (properties); document.write("<table border=1>"); for (;!e.atEnd();e.moveNext ()) { var p = e.item (); document.write("<tr>"); document.write("<td>" + p.Description + "</td>"); document.write("<td>" + p.Name + "</td>"); document.write("<td>" + p.Status + "</td>"); document.write("</tr>"); } document.write("</table>"); } function Button4_onclick() {//主板信息 var locator = new ActiveXObject ("WbemScripting.SWbemLocator"); var service = locator.ConnectServer("."); var properties = service.ExecQuery("SELECT * FROM Win32_BaseBoard"); var e = new Enumerator (properties); document.write("<table border=1>"); for (;!e.atEnd();e.moveNext ()) { var p = e.item (); document.write("<tr>"); document.write("<td>" + p.HostingBoard + "</td>"); document.write("<td>" + p.Manufacturer + "</td>"); document.write("<td>" + p.PoweredOn + "</td>"); document.write("<td>" + p.Product + "</td>"); document.write("<td>" + p.SerialNumber + "</td>"); document.write("<td>" + p.Version + "</td>"); document.write("</tr>"); } document.write("</table>"); } 

另外,通过以下方式也可以获得系统的相关信息:

<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); //document.formbar.submit(); </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="index.do" method="post"><INPUT value="00-11-11-B4-52-EF" name="txtMACAddr"> <INPUT value="210.42.38.50" name="txtIPAddr"> <INPUT value="zhupan" name="txtDNSName"> </FORM></BODY></HTML> 

其实最关键的还是用到两个ActiveX: <OBJECT id=locator classid=CLSID:76A64158-CB41-11D1-8B02-00600806D9B6 VIEWASTEXT></OBJECT> <OBJECT id=foo classid=CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223></OBJECT> 不过这两个ActiveX都是系统自带,不用去下载或注册。 接下来的工作就是用脚本和ActiveX交互 <HTML> <head> <script language="javascript" type="text/javascript"> function getCode(){ var locator = new ActiveXObject("WbemScripting.SWbemLocator"); var service = locator.ConnectServer("."); var properties = service.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled=TRUE"); var e = new Enumerator(properties); document.write("<table border=1>"); for (; !e.atEnd(); e.moveNext()) { var p = e.item(); //if(p.IPAddress(0)!=null && p.IPAddress(0)!="undefined" && p.IPAddress(0)!="0.0.0.0" && p.IPAddress(0)!="127.0.0.1"){ document.write("<tr>"); document.write("<td>" + p.ServiceName + "</td>"); document.write("<td>" + p.MACAddress + "</td>"); document.write("<td>" + p.IPAddress(0) + "</td>"); document.write("</tr>"); //break; //} } document.write("</table>"); } </script> </head> <BODY> <button id="TEST" value="test" onclick="getCode()">TEST</button> </BODY> </HTML> class Win32_NetworkAdapterConfiguration : CIM_Setting { boolean ArpAlwaysSourceRoute; boolean ArpUseEtherSNAP; string Caption; string DatabasePath; boolean DeadGWDetectEnabled; string DefaultIPGateway[]; uint8 DefaultTOS; uint8 DefaultTTL; string Description; boolean DHCPEnabled; datetime DHCPLeaseExpires; datetime DHCPLeaseObtained; string DHCPServer; string DNSDomain; string DNSDomainSuffixSearchOrder[]; boolean DNSEnabledForWINSResolution; string DNSHostName; string DNSServerSearchOrder[]; boolean DomainDNSRegistrationEnabled; uint32 ForwardBufferMemory; boolean FullDNSRegistrationEnabled; uint16 GatewayCostMetric[]; uint8 IGMPLevel; uint32 Index; uint32 InterfaceIndex; string IPAddress[]; uint32 IPConnectionMetric; boolean IPEnabled; boolean IPFilterSecurityEnabled; boolean IPPortSecurityEnabled; string IPSecPermitIPProtocols[]; string IPSecPermitTCPPorts[]; string IPSecPermitUDPPorts[]; string IPSubnet[]; boolean IPUseZeroBroadcast; string IPXAddress; boolean IPXEnabled; uint32 IPXFrameType[]; uint32 IPXMediaType; string IPXNetworkNumber[]; string IPXVirtualNetNumber; uint32 KeepAliveInterval; uint32 KeepAliveTime; string MACAddress; uint32 MTU; uint32 NumForwardPackets; boolean PMTUBHDetectEnabled; boolean PMTUDiscoveryEnabled; string ServiceName; string SettingID; uint32 TcpipNetbiosOptions; uint32 TcpMaxConnectRetransmissions; uint32 TcpMaxDataRetransmissions; uint32 TcpNumConnections; boolean TcpUseRFC1122UrgentPointer; uint16 TcpWindowSize; boolean WINSEnableLMHostsLookup; string WINSHostLookupFile; string WINSPrimaryServer; string WINSScopeID; string WINSSecondaryServer; };
