У меня есть код, который я использую для фильтрации некоторых пользовательских параметров, но я бы хотел использовать существующую таблицу html в качестве источника данных для поля igcombo, а не для массива javascript. Как я могу это сделать? Вот мой код:Cascading combobox с html-таблицей как datasource

Это отлично! однако фактическая таблица html, которую я должен использовать, не имеет «th» тегов или «id», есть ли способ, которым ваш код может это объяснить? Я обновил код выше. – dmoses
Можете ли вы получить это для каскада, основанного на выборе – dmoses
Я думаю, что да, но вы должны сделать это с данными, повторенными в первом столбце, чтобы фильтровать –
