Jquery count number of hidden elements within div

Question

How can I count the number of items in div that are hidden?

Thanks in advance

Answer 1

I think that

$("#someElement > *").filter(":hidden").size();

will work.

Updated: Added the '*'. Note that this will select the immediate children of #someElement.

Answer 2

Direct children of someElement that are hidden:

$('#someElement > :hidden').length;

Any descendants of someElement that are hidden:

$('#someElement :hidden').length;

If you already have a jQuery object you can use it as the context:

var ele = $('#someElement');

$(':hidden', ele).length;

Answer 3

$("#someElement *:hidden").size()
