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.
