1. To check the status of a single checkbox you can use :checked selector as bellow:
$('#' + id).is(":checked")2. To get the array value of checkboxes selected with the same name:
var checkbox = $('.form .form-item input[name=hobbies]:checked'); // return list checkbox object selectedAnd then you can loop through them and see what's checked you can do:
checkbox.each(function(){ // Do stuff here with this });3. To validate form you can check the length of checkbox variable
if(checkbox == null || checkbox.length <= 0){ // show msg error here }See demo code
