如何在react-big-calander onSelectEvent的警报中显示两个事件项

npm install react-big-calendar

import { Calendar, momentLocalizer } from 'react-big-calendar';
import moment from 'moment';
import 'react-big-calendar/lib/css/react-big-calendar.css';

const localizer = momentLocalizer(moment);

const events = [
  {
    title: '事件项1',
    start: new Date(2022, 8, 1),
    end: new Date(2022, 8, 3),
  },
  {
    title: '事件项2',
    start: new Date(2022, 8, 5),
    end: new Date(2022, 8, 7),
  },
];

const handleSelectEvent = (event) => {
  alert(`选中的事件项：${event.title}`);
  // 在警报中显示两个事件项
  alert(`事件项1：${events[0].title}\n事件项2：${events[1].title}`);
};

const App = () => {
  return (
    <div>
      <Calendar
        localizer={localizer}
        events={events}
        startAccessor="start"
        endAccessor="end"
        onSelectEvent={handleSelectEvent}
      />
    </div>
  );
};
