Question

I would like to detect whether the user has pressed any key when a modal is shown. I tried the following code but the events are not fired.

I found the solution to my problem. It seems like I should not point to the id of the modal so that the keypress event will be detected.

$(document).on('keydown keyup input click',  function (e) {
if($('#modal_confirmation_dp_change').is(':visible')) {
            var key = e.which;
                if (key == 13) { //This is an ENTER 
                    $('#changed_dp_ok').click();
                }
        }
    });
