Check opacity by jQuery

Question

How do I check if the opacity of an element is 0, and then do something in jQuery?

Answer 1

Have you tried using .css()?

if($('elemFoo').css('opacity') == 0) {     doSomething(); } 

Answer 2

You can do as

$(function() {      if ($('#foo').css('opacity') == 0)         alert('lol');  });
