Comment 1 for bug 1709966

for reference, the XUL code does this:

/* HOLD_CAPTURE_DELAYED */ if (check.ilsevent == 7019) {

            check.what_happened = 'hold_capture_delayed';
            sound.special('checkin.hold_capture_delayed');
            var rv = 0;
            msg += document.getElementById('circStrings').getString('staff.circ.utils.hold_capture_delayed.description');
            if (!suppress_popups) {
                rv = error.yns_alert_formatted(
                    msg,
                    document.getElementById('circStrings').getString('staff.circ.utils.hold_capture_delayed.titlebar'),
                    document.getElementById('circStrings').getString('staff.circ.utils.hold_capture_delayed.prompt_for_nocapture'),
                    document.getElementById('circStrings').getString('staff.circ.utils.hold_capture_delayed.prompt_for_capture'),
                    null,
                    document.getElementById('circStrings').getString('staff.circ.confirm.msg'),
                    '/xul/server/skin/media/images/stop_sign.png'
                );
            } else {
                // FIXME: add SFX and/or GFX
                sound.circ_bad();
            }
            params.capture = rv == 0 ? 'nocapture' : 'capture';

            return circ.util.checkin_via_barcode(session,params,backdate,auto_print,false);

        }
