JavaScript gets client computer hardware and system Information

To obtain client computer hardware and system information through WMI:

//System Information AcquisitionfunctionGetsysinfo () {varLocator =NewActiveXObject ("WbemScripting.SWbemLocator"); varService = Locator. ConnectServer ("."); //CPU Information    varCPU =NewEnumerator (service. ExecQuery ("SELECT * from Win32_Processor") . Item (); varCputype=cpu. Name,hostname=CPU.     SystemName; //Memory Information    varMemory =NewEnumerator (service. ExecQuery ("SELECT * from Win32_physicalmemory"));  for(varmem=[],i=0;! Memory.atend (); Memory.movenext ()) Mem[i++]={cap:memory.item (). capacity/1024/1024, Speed:memory.item (). Speed}//System Information    varsystem=NewEnumerator (service. ExecQuery ("SELECT * from Win32_ComputerSystem") . Item (); varPhysicmencap=math.ceil (System. totalphysicalmemory/1024/1024), Curuser=system. Username,cpucount=System. NumberOfProcessorsreturn{Cputype:cputype,cpucount:cpucount,hostname:hostname,curuser:curuser,memcap:physicmencap,mem:mem}}

The code implementation mainly includes these parts:  

1. First through new ActiveXObject ("WbemScripting.SWbemLocator"); Access to the WbemScripting object.
2. Through locator. ConnectServer ("."); Connect our local computer (.) on behalf of the local computer, of course
3. You can also access other computers).
4. Through the service. ExecQuery ("SELECT * from Win32_Processor") This SQL-like statement (in fact the system information is also stored in a database-like file in the calculation) gets the recordset of the object we need.
5. Using new enumerator to create an enumerable object, you can iterate through the information below.

Note: The prerequisite for the operation is to modify the browser security settings, "Allow ActiveX that is not marked as safe to perform
Script to run ".

Here the main CPU, memory and system users a few information, we use the WMI API or with the help of Jsedit get
to more information. The following is a list of common information classes:
