jQuery $('#submitForm').find('form') vs jQuery $('#submitForm form') -

-

i wondering of both methods faster:

selecting container , form @ in 1 statement:

jquery $('#submitform form')

or using jquery's .find() selector:

jquery $('#submitform').find('form')

the .find() approach faster because first selection handled without going through sizzle selector engine – id-only selections handled using document.getelementbyid(), extremely fast because native browser.

so

jquery $('#submitform').find('form')

is faster than

jquery $('#submitform form')

selector optimization less important used be, more browsers implement document.queryselectorall() , burden of selection shifts jquery browser.

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
