I am trying to add to array checked checkboxes, but the array comes up empty, what am I doing wrong on my script?
var availability = [];
$('input[type="checkbox"]').change(function() {
$('.availability input:checked').each(function() {
availability.push($(this).attr('name'));
});
console.log(availability);
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
