javascript — [Leaflet] Как изменить карту и ее границу?

Добрый вечер тоже всем!

У меня есть веб-сайт с картой листовок, которая сфокусирована на области, и эта область ограничена. Граничная область является редактируемой, и за пределами этой области находится весь мир, который нельзя редактировать. Если вы не очищены, вот образец.

Это Leaflet Map, которая ориентирована на область, и эта область ограничена.

и код для этого здесь

Вывод 2-го кода выше должен быть изображением в ссылке выше

1-й код и 2-й код выше имеют одинаковые выходные данные, но имеют разную область и форму границы Теперь мой вопрос: если я нажму кнопку области 1, карта перейдет в область 1 с рамкой, а если я нажму кнопку области 2, она перейдет в область 2 с рамкой.

Простой вопрос: изменить область карты и границы во время нажатия кнопки
