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：Win32_Processor / CPU 处理器Win32_PhysicalMemory / 物理内存Win32_Keyboard / 键盘Win32_PointingDevice / 点输入设备，如鼠标Win32_DiskDrive / 硬盘驱动器Win32_CDROMDrive / 光盘驱动器Win32_BaseBoard / 主板Win32_BIOS / BIOS 芯片Win32_ParallelPort / 并口Win32_SerialPort / 串口Win32_SoundDevice / 多媒体设置Win32_USBController / USB 控制器Win32_NetworkAdapter / 网络适配器Win32_NetworkAdapterConfiguration / 网络适配器设置Win32_Printer / 打印机Win32_PrinterConfiguration / 打印机设置Win32_PrintJob / 打印机任务Win32_TCPIPPrinterPort / 打印机端口Win32_POTSModem / MODEMWin32_POTSModemToSerialPort / MODEM 端口Win32_DesktopMonitor / 显示器Win32_VideoController / 显卡细节。Win32_VideoSettings / 显卡支持的显示模式。Win32_TimeZone / 时区Win32_SystemDriver / 驱动程序Win32_DiskPartition / 磁盘分区Win32_LogicalDisk / 逻辑磁盘Win32_LogicalMemoryConfiguration / 逻辑内存配置Win32_PageFile / 系统页文件信息Win32_PageFileSetting / 页文件设置Win32_BootConfiguration / 系统启动配置Win32_OperatingSystem / 操作系统信息Win32_StartupCommand / 系统自动启动程序Win32_Service / 系统安装的服务Win32_Group / 系统管理组Win32_GroupUser / 系统组帐号Win32_UserAccount / 用户帐号Win32_Process / 系统进程Win32_Thread / 系统线程Win32_Share / 共享Win32_NetworkClient / 已安装的网络客户端Win32_NetworkProtocol / 已安装的网络协议WMI Win32类的完整信息及详细列表请参考MSDN:/en-us/library/aa394084(VS.85).aspx示例：1function button1_onclick() /cpu 信息2 var locator = new ActiveXObject (WbemScripting.SWbemLocator);3 var service = locator.ConnectServer(.);4 var properties = service.ExecQuery(SELECT * FROM Win32_Processor);5 var e = new Enumerator (properties);6 document.write(table border=1);7 for (;
