Hello wonderful people,Обновить изображение после Src Изменение атрибута
Я пытаюсь обновить изображение после изменения атрибута 'src'. Я попытался добавить URL-адрес с отметкой даты, но это, похоже, не работает. Может ли кто-нибудь показать мне, где я ошибаюсь, или просто предложить лучший способ сделать все это вместе?
Я включил весь свой код на сегодняшний день, так как я не уверен, где проблема. Я немного боюсь, я боюсь. Первые три строки в функции displayOut наиболее вероятно, где проблема. Спасибо заранее за вашу помощь.

Я только начинаю использовать как «пусть» и «Const», это просто способ обеспечения правильного объем. Я знаю, что это не обязательно, где я это сказал, но это хорошая практика для будущего моего развития, я думаю. – Cuckoo
