Update  In the past few years the landscape has changed drastically   You can now reliably use querySelector and querySelectorAll  see Wojtek s answer for how to do this     There s no need for a jQuery dependency now   If you re using jQuery  great   if you re not  you need not rely it on just for selecting elements by attributes anymore     There s not a very short way to do this in vanilla javascript  but there are some solutions available   You do something like this  looping through elements and checking the attribute  If a library like jQuery is an option  you can do it a bit easier  like this       myAttribute value      If the value isn t a valid CSS identifier  it has spaces or punctuation in it  etc    you need quotes around the value  they can be single or double        myAttribute  my value       You can also do start-with  ends-with  contains  etc   there are several options for the attribute selector
