怎样用JS获取客户端的硬件，系统等信息

Answer 1

通过WMI来实现获取客户端计算机硬件及系统信息:
1//系统信息获取
2function getSysInfo(){
3 var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
4 var service = locator.ConnectServer(".");
5 //CPU信息
6 var cpu = new Enumerator (service.ExecQuery("SELECT * FROM Win32_Processor")).item();
7 var cpuType=cpu.Name,hostName=cpu.SystemName;
8 //内存信息
9 var memory = new Enumerator (service.ExecQuery("SELECT * FROM Win32_PhysicalMemory"));
10 for (var mem=[],i=0; !memory.atEnd(); memory.moveNext()) mem[i++]={cap:memory.item().Capacity/1024/1024,speed:memory.item().Speed}
11 //系统信息
12 var system=new Enumerator (service.ExecQuery("SELECT * FROM Win32_ComputerSystem")).item();
13 var physicMenCap=Math.ceil(system.TotalPhysicalMemory/1024/1024),curUser=system.UserName,cpuCount=system.NumberOfProcessors
14
15 return {cpuType:cpuType,cpuCount:cpuCount,hostName:hostName,curUser:curUser,memCap:physicMenCap,mem:mem}
16}
