JavaScript 获取客户端计算机硬件及系统信息
通過WMI來實(shí)現(xiàn)獲取客戶端計(jì)算機(jī)硬件及系統(tǒng)信息:
//系統(tǒng)信息獲取 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; //內(nèi)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} //系統(tǒng)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}
}
代碼實(shí)現(xiàn)主要包括這幾部分：??
- ?
- 先通過new ActiveXObject ("WbemScripting.SWbemLocator"); 訪問到WbemScripting對象。
- 通過locator.ConnectServer(".");連接我們本地電腦（.代表本地電腦，當(dāng)然
- 也可以訪問其他計(jì)算機(jī)）。
- 通過service.ExecQuery("SELECT * FROM Win32_Processor")這個(gè)類似sql的語句（其實(shí)系統(tǒng)信息也是存儲在計(jì)算中一個(gè)類似數(shù)據(jù)庫的文件中）獲取我們需要的對象的記錄集。
- 通過new Enumerator來創(chuàng)建一個(gè)可枚舉的對象，下面就可以遍歷取信息了。?

注意：運(yùn)行的前提是要修改瀏覽器安全設(shè)置，“允許對未標(biāo)記為可安全執(zhí)行的ActiveX
腳本的運(yùn)行”。這里主要取了CPU、內(nèi)存及系統(tǒng)用戶幾個(gè)信息，大家利用WMI的API或者借助JSEDIT獲取
