Setting “checked” for a checkbox with jQuery? 38 answers

'checked' property is boolean but it means when it not exists it is false. If you need not submit on click or don't go to link there is e.preventDefault() . So you need this:

 $('#remove-button').click(function(e) {
    $('input:checked').removeAttr('checked');
    e.preventDefault();
 });
 $('#add-button').click(function(e) {
   var input = $('input.input-to-check')
   input.attr('checked', 'checked');
   e.preventDefault();
 });
