Доступ к массиву JSON и отображение JQuery

Привет У меня есть следующий массив JSON, я хотел бы знать, как отображать элемент в div с помощью jquery.Доступ к массиву JSON и отображение JQuery

, например, первый cloudcover в объекте погоды

Следующая не работает для меня

document.getElementById ("examplediv"). InnerHTML = данные [0] .weather [0] .hourly [0] .cloudcover;

назначение не работает, так как данные не является массивом, и вам не нужно, чтобы получить доступ к первому элементу, изменение кода будет:

document.getElementById("examplediv").innerHTML = data.weather[0].hourly[0].cloudcover;

Основная проблема с этим громоздким запроса является то, что это не null безопасно, и я рекомендовал бы добавить null проверки для всех суб-значений.

Данные - это объект, а не массив.

Попробуйте

document.getElementById("examplediv").innerHTML = data.weather[0].hourly[0].cloudcover;

вместо

document.getElementById("examplediv").innerHTML = data[0].weather[0].hourly[0].cloudcover;

Вы можете использовать jquery.parseJson для разбора JSON в объект яваскрипта и использовать его для различных целей. Следующий jquery может дать вам представление о том, как это делается.
