Получение доступа к элементам массива JSON

Итак .getgets возвращает список объектов, которые являются дорожками в музыкальном плейлисте, и каждый трек имеет поле элемента «title», которое я хочу получить и распечатать на экране. Как мне пройти через индексы объектов (0-25) и перечислить их элементы заголовка?Получение доступа к элементам массива JSON

widget.getSounds(function(sound) { 
console.log(sound); 
});

пример из консоли JSON:

Не могли бы вы отредактировать свое сообщение с помощью примера JSON? –

Возможно, все, что вам нужно, это цикл 'for' ... –

Функция each() в jQuery – EnterJQ

Так вы говорите .getSounds() возвращает список объектов, вы можете просто запустить их через для петли.

var songs = widget.getSounds(); 
for (var i = 0; i < songs.length; i++) { 
    var songTitle = songs[i].title; 
    console.log(songTitle); 
}
