how use part of id or class of dom element jquery selector?

i.e. have 

id="some_extra_name"

can use "extra" elements jquery?

yes, can do

$elements = $('[id*=extra]');

if wanted elements id starts "extra", you'd 

$elements = $('[id^=extra]');

and elements id ends "extra" :

$elements = $('[id$=extra]');
