JavaScript 获取客户端计算机硬件及系统信息

發布時間：2024/9/30 javascript 29 豆豆

生活随笔收集整理的這篇文章主要介紹了 JavaScript 获取客户端计算机硬件及系统信息小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

通過WMI來實現獲取客戶端計算機硬件及系統信息:
//系統信息獲取 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} }

代碼實現主要包括這幾部分：??

?
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，當然
也可以訪問其他計算機）。
通過service.ExecQuery("SELECT * FROM Win32_Processor")這個類似sql的語句（其實系統信息也是存儲在計算中一個類似數據庫的文件中）獲取我們需要的對象的記錄集。
通過new Enumerator來創建一個可枚舉的對象，下面就可以遍歷取信息了。?
注意：運行的前提是要修改瀏覽器安全設置，“允許對未標記為可安全執行的ActiveX
腳本的運行”。

這里主要取了CPU、內存及系統用戶幾個信息，大家利用WMI的API或者借助JSEDIT獲取
到更多的信息。下面列出了常用信息的類：
