У меня есть данные формата json:
"records":[
{
"status":"active",
"version":5,
"assigned_to":null,
"form_values":
{
"lastName":"Doe",
"photos":
[
{
"photo_id":"ahfhghea08-c938-4ea7",
"caption":null
},
{
"photo_id":"38ffgh847d-0ced-4425",
"caption":null
},
{
"photo_id":"7hgj6a264-cba7-4165",
"caption":null
}
]
},
"status":"active",
"version":1,
"assigned_to":null,
"form_values":
{
"lastName":"James",
"photos":
[
{
"photo_id":"ahfhghea08-c938-4ea7",
"caption":null
}
]
}
}
]
Я пытаюсь l oop через массив фотографий и добавить только photo_id без заголовка, разделенного на%.
Вывод должен быть таким: https://web.photos.com/photos/view?photos=ahfhghea08-c938-4ea7%38ffgh847d-0ced-4425%7hgj6a264-cba7-4165
Я могу отобразить его только с одним photo_id, и это вывод, который я получаю: https://web.photos.com/photos/view?photos=ahfhghea08-c938-4ea7
, когда я пытаюсь добавить второй photo_id, я получаю эту ошибку "не могу прочитать свойство photo_id из неопределенного". потому что иногда есть только 1 photo_id, а не несколько photo_id.
Я пишу сценарий, используя Javascript в Пентахо.
Обновление:
Это ввод json:

Я пытаюсь получить значение photo_id в атрибуте photos. Это: "photos":[{"photo_id":"918564fa9-eacc-585b9b-aa3e-a09637b1188","caption":null}]
Как вы можете видеть на входе json, иногда массив photos может содержать только одно значение photo_id, а иногда может содержать более одного. Когда доступно несколько значений photo_id, мне нужно объединить значения в этом формате: https://web.photos.com/photos/view?photos=(1st photo_id value)%(2nd photo_id value)%....
Я могу прочитать значение 1-го photo_id следующим образом: ['photos'])[0] ['photo_id'], но когда значение 2-го photo_id равно не предоставлено, я получаю неопределенный, и скрипт сломался.
Как я могу проверить, предоставлен ли 2-й photo_id, затем объединить его со строкой URL?
