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.
