Question

I have two sets of check boxes. At least one in each group has to be checked. How do I accomplish this with Jquery? Here is my link to JS Fiddle:

Answer 1

do a:

$('ul:has(input[type="checkbox"]:checked)').length == 2

where 2 is the number of groups. It gives you the number of ul’s that contain a checked input that has to be 2 in this case 😉 So it checks that every ul that contains checkboxes has at least one checked.
