Question

I have a large list of check boxes all with unique id values. I’d like to get the id of the checkbox that executes my JavaScript function. Can I do this using $(this)?

Answer 1

You can get the target of the event using event.target.

$('input:checkbox[id]').change(function(event) {
  var checkboxID = $(event.target).attr('id');
  alert(checkboxID);
});
