В настоящее время я работаю над проектом, который включает в себя отображение множества пользовательских маркеров на карте, а затем создание всплывающей страницы при нажатии. Эта проблема у меня, будучи новичком в javascript, получает второе маркерное изображение, отображаемое на карте. Итак, у меня есть следующий код, как вы видите, значки «камеры» работают ... но для работы также нужен «caltex» ...:
