嵌套物件中的嵌套陣列

2022-01-15 21:03:33 .NET開發

我有一個物件，其結構是

const data = {

    "responce": [

                        ]
                    },
                    {
                        "title": "heading test"
                    }
                ]
            },
            "responce_ID": "7aeb2a42-a5f8-464d-832d-47cee4cfdb38",
            "responce_name": "uttence_heading_test",
            "updated_BY": "",
            "user_ID": "av1234"
        }
    ],
    "status_code": 0
}

我能夠通過使用提取以下物件陣列 data.responce.map(responce => responce.responce)

[{
  uttence_test_heading: [{
  buttons: [{
  payload: "/my_localities",
  title: "savings"
}, {
  payload: "/my_localities12333qqqwq",
  title: "current"
}, {
  payload: "/fruits",
  title: "platinum"
}]
}, {
  title: "Test Heading"
}]
}, {
  utter_content: [{
  text: "text_title for buttonqwqwq"
}]
}, {
  uttence_text_heading: [{
  buttons: [{
  payload: "/my_localities",
  title: "savings"
}, {
  payload: "/my_localities12333qqqwq",
  title: "current"
}, {
  payload: "/test",
  title: "premium"
}]
}, {
  title: "Text Heading"
}]
}, {
  uttence_heading_test: [{
  buttons: [{
  payload: "/my_localities",
  title: "savings"
}, {
  payload: "/fruits",
  title: "current"
}, {
  payload: "/undefined",
  title: "premium"
}]
}, {
  title: "heading test"
}]
}]

現在我想構造一個物件陣列，其結構如下所示

這是我的預期結果，但我被卡住了，因為 uttence_name 是一個鍵，并且每個物件都不同，所以有人可以指導我如何實作我的預期結果。請幫忙 ！

[{uttence_name: ' uttence_test_heading',buttons: ['savings','current','platinum'],text: '',responce_ID:'6bbb20d6-7f71-408a-a78a-bab39a30016f'},
{uttence_name: 'utter_content',buttons: '',text: 'text_title for buttonqwqwq',responce_ID:'81d699ee-3e78-4356-b703-af095d91e36b'},
{uttence_name:'uttence_text_heading',buttons:['savings','current','premium'],text: '',responce_ID:'bb6b0005-bbd4-49a1-8b25-58e0768800a1'}]

您可以鏈接一秒鐘map并獲得所需的結果。但我的回答假設陣列中只有一個專案。

另外，我不太明白你想用它做什么，buttons所以我把它們保存為一個陣列。

您可以運行下面的代碼片段來查看是否獲得了所需的輸出。

這是根據您提供的資料所需的結果。在代碼中，最好的情況是，它檢查您是否有包含文本的物件，然后相應地添加資料。它也有response_ID
