I also just found jQuery.isEmptyObject()!! So... if ($('.none').isEmptyObject()) { } ...should also work. :/ . ...and another one - this time without using a function... obj = $('.none'); if (!obj[0]) { } this looks for a first item in the object, if none found run the code, again untested :P ... geez… I also just found jQuery.isEmptyObject()!! So…

if ($(‘.none’).isEmptyObject()) { }

…should also work. :/

.

…and another one – this time without using a function…

obj = $(‘.none’);
if (!obj[0]) { }

this looks for a first item in the object, if none found run the code, again untested :P

What you proposed would do the opposite. But if you hate the '==' so much you can optimize out a few characters with the ! operand. Perhaps you meant

if (!$(‘.none’).length) { }
