По сути работает всё, кроме кнопки проверки. Юзеру нужно в левом ряду выставить цвета радуги. Почему-то, при перемещении объектов с одной ячейки в другую не передаётся backgroundColor, это я проверил в консоли. Т.е как вначале заспавнилось "Aqua" в id 1, хоть куда его перемещай, но Aqua останется только в этом div'e с id 1. Не могли бы пожалуйста помочь заставить работать правильно эту зласчастную кнопку? |
Цитата:
style.backgroundColor == ccc[ccc.length - 1]) |
С самим Drag'n'drop'ом всё в порядке? Думал, что в нём проблема. Можно немного разъяснить про data-color, data-index? Первый раз имею с ними дело

собери радугу
