JAVASCRIPT 对象到数组的转换

Question

在发布我的问题之前，我在 stackoverflow 上进行了搜索，但没有找到任何解决方案。我有一个像这样的对象:

"{"COURRIERS":
     {"05. Juridique":
         [{"res_id":100,"type_label":"Plainte","subject":"test23","doctypes_first_level_label":"COURRIERS","doctypes_second_level_label":"05. Juridique","folder_level":2}]
     }
}"

我需要像数组一样访问它，以便获取 res_id 等信息。

我该怎么做？

提前致谢

假设每一层中不会有多个对象/数组，这应该可以满足您的需要。

let obj = {
  "COURRIERS": {
    "05. Juridique": [{
      "res_id": 100,
      "type_label": "Plainte",
      "subject": "test23",
      "doctypes_first_level_label": "COURRIERS",
      "doctypes_second_level_label": "05. Juridique",
      "folder_level": 2
    }]
  }
}

let folder = Object.keys(obj)[0]
let type = Object.keys(obj[folder])[0]
let result = obj[folder][type][0]

console.log(result)
