Я пытаюсь работать с Mapbox (потому что Карты теперь платные), и мой сервис в основном:
- Пользователь создает маршрут, касаясь карты *** Сервис принимает координаты и create
- Созданный маршрут сохраняется в базе данных (js или php, я понятия не имею, как лучше это сделать)
- После закрытия windows, когда пользователь возвращается на веб-сайт, маршруты (шаг 1) будут там.
Моя настоящая проблема - точно показать маршрут, я не могу понять документацию ... Итак, я использую массив для каждого щелчка (и это работает), но как завершить следующий шаг (4)?
