Это мой JQuery код:

var indiceMateria = $('table#tabla_materia tr.ptype input.ptype[value="148"]').index(); 
console.log('FILA DE LA MATERIA PRIMA: '+indiceMateria); // 1

Что может быть проблема ??. Пожалуйста, помогите. Спасибо.

Он всегда будет возвращать '1', потому что вход с классом' ptype' и значением '148' является вторым элементом внутри его родителя. Что вы ожидаете, чтобы заставить его вернуться по-другому? –

Я думал, что функция index() возвращает индекс, рассматривая только элемент tr таблицы. Таким образом, он возвращает индекс ближайшего элемента? – juanpscotto

Он возвращает индекс элемента относительно его прямого родительского элемента. В этом случае родительский элемент - это 'td', а элемент' input.ptype' - это второй элемент внутри 'td' –

селектор выбирает td элемент и возвращает индекс td, который всегда будет 1, так как это единственный td элемент внутри родительского tr. Используйте closest('tr'), чтобы получить индекс tr.

var indiceMateria = $('#tabla_materia tr.ptype input.ptype[value="148"]').closest('tr').index(); 
//                  ^^^^^^^^^^^^^
