javascript - 通过 ID 从数组中获取特定 JSON 对象并返回 JSON 对象 (Javascript/JQuery)

Question

我正在尝试使用 JavaScript 从对象数组中提取特定的 JSON 对象。这是我的 JSON:

"Awards": [
   {
     "Award1": {
        "title": "Award1 Title",
        "recipient": "John Doe",
        "description": "Blah Blah Blah"
     }
   },
   {
     "Award2": {
        "title": "Award2 Title",
        "recipient": "Tom White",
        "description": "Blah Blah Blah"
     }
   },
   {
      "Award3": {
         "title": "Award3 Title",
         "recipient": "Will Biggs",
         "description": "Blah Blah Blah"
      }
   }
]

我想要做的是创建一个函数，它接受数据和 id，在数组中查找对象并返回整个对象。例如，如果我搜索 Award1，我希望它返回:

var obj = {
 "title": "Award1 Title",
 "recipient": "John Doe",
 "description": "Blah Blah Blah"
}

然后我就可以像这样访问数据:

obj.recipient // Which would return John Doe

想法？

Answer 1

查找包含属性 key=Award1 的第一个对象并返回它。

const findKey = (list, key)=>(list.find(obj=>obj[key])||{})[key]

data = {
"Awards": [
   {
     "Award1": {
        "title": "Award1 Title",
        "recipient": "John Doe",
        "description": "Blah Blah Blah"
     }
   },
   {
     "Award2": {
        "title": "Award2 Title",
        "recipient": "Tom White",
        "description": "Blah Blah Blah"
     }
   },
   {
      "Award3": {
         "title": "Award3 Title",
         "recipient": "Will Biggs",
         "description": "Blah Blah Blah"
      }
   }
]
}

console.log(data.Awards.find(obj=>obj["Award1"]))

let key = "Award1"
console.log(data.Awards.find(obj=>obj[key])[key].title)

console.log(
findKey(data.Awards,'Award1')
)

console.log(
findKey(data.Awards,'Award2')
)

console.log(
findKey(data.Awards,'Award3')
)
