JavaScript 获取客户端计算机硬件及系统信（国外英文资料） JavaScript gets the client computer hardware and system information The function fnShowPrcName (prcName) { Var locator = new ActiveXObject ( WbemScripting.

Processen.atend (); processenen.movenext ()) { Var process = processen.item (); If ( = = prcName) { Flag = true; } } If (flag) { Alert (prcName) } else { Alert ( not found this process ) } } Obtaining client computer hardware and system information through WMI: 1 / / system information retrieval 2 the function getSysInfo () { 3 var locator = new ActiveXObject ( WbemScripting. 4 var service = locator.

SWbemLocator ); Access to WbemScripting objects. By locator. ConnectServer (. ); Connect to our local computer (on behalf of the local computer, of course You can also access other computers. Through service. ExecQuery ( SELECT * FROM Win32_Processor ) this is similar to SQL statements (actually a similar in the calculation of system information is stored in the database file) we need for the record
