嵌套 object 中的嵌套数组

Question

我有一个 object 的结构是

const data = {
    "message": "fetch responces successfully",
    "responce": [
        {
            "created_AT": "Mon, 03 Jan 2022 17:39:24 GMT",

                                "title": "savings"
                            },

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

我能够使用data.responce.map(responce => responce.responce)提取以下对象数组

[{
  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"
}]
}]

现在我想构造一个对象数组，其结构如下所示

这是我的预期结果，但我被卡住了，因为 uttence_name 是一个键，并且每个 object 都不同，所以有人可以指导我如何实现我的预期结果。 请帮忙 ！

[{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'}]

Answer 1

您可以链接第二个map并获得所需的结果。 但我的回答假设 arrays 只有一个项目。

另外，我不太明白你想用这些buttons做什么，所以我把它们保存为一个数组。

您可以运行下面的代码片段来查看是否获得了所需的 output。

 const data={message:"fetch responces successfully",responce:[{created_AT:"Mon, 03 Jan 2022 17:39:24 GMT",created_BY:"avinash",dateTime:"Mon, 03 Jan 2022 17:39:24 GMT",deleted_BY:"",flag:0,project_ID:"infobot1234",responce:{uttence_test_heading:[{buttons:[{payload:"/my_localities",title:"savings",},{payload:"/my_localities12333qqqwq",title:"current",},{payload:"/fruits",title:"platinum",},],},{title:"Test Heading",},],},responce_ID:"6bbb20d6-7f71-408a-a78a-bab39a30016f",responce_name:"uttence_test_heading",updated_BY:"",user_ID:"av1234",},{created_AT:"Tue, 04 Jan 2022 17:49:36 GMT",created_BY:"avinash",dateTime:"Tue, 04 Jan 2022 17:49:36 GMT",deleted_BY:"",flag:0,project_ID:"infobot1234",responce:{utter_content:[{text:"text_title for buttonqwqwq",},],},responce_ID:"81d699ee-3e78-4356-b703-af095d91e36b",responce_name:"utter_txt1234",updated_BY:"",user_ID:"av1234",},{created_AT:"Thu, 13 Jan 2022 18:06:39 GMT",created_BY:"avinash",dateTime:"Thu, 13 Jan 2022 18:06:39 GMT",deleted_BY:"",flag:0,project_ID:"infobot1234",responce:{uttence_text_heading:[{buttons:[{payload:"/my_localities",title:"savings",},{payload:"/my_localities12333qqqwq",title:"current",},{payload:"/test",title:"premium",},],},{title:"Text Heading",},],},responce_ID:"bb6b0005-bbd4-49a1-8b25-58e0768800a1",responce_name:"uttence_text_heading",updated_BY:"",user_ID:"av1234",},{created_AT:"Thu, 13 Jan 2022 20:13:54 GMT",created_BY:"avinash",dateTime:"Thu, 13 Jan 2022 20:13:54 GMT",deleted_BY:"",flag:0,project_ID:"infobot1234",responce:{uttence_heading_test:[{buttons:[{payload:"/my_localities",title:"savings",},{payload:"/fruits",title:"current",},{payload:"/undefined",title:"premium",},],},{title:"heading test",},],},responce_ID:"7aeb2a42-a5f8-464d-832d-47cee4cfdb38",responce_name:"uttence_heading_test",updated_BY:"",user_ID:"av1234",},],status_code:0,} const result = data.responce.map((res) => ({...res.responce, responce_ID: res.responce_ID })).map((obj) => ({ utterance_name: Object.keys(obj)[0], text: Object.values(obj)[0][0].text || "", buttons: Object.values(obj)[0][0].buttons?.map((btn) => btn.title) || "", responce_ID: obj.responce_ID })); console.log(result);

Answer 2

使用map 、 find 、 some和? 的示例。 可选链和?? 空值合并运算符

 const data = { message: "fetch responces successfully", responce: [ { created_AT: "Mon, 03 Jan 2022 17:39:24 GMT", created_BY: "avinash", dateTime: "Mon, 03 Jan 2022 17:39:24 GMT", deleted_BY: "", flag: 0, project_ID: "infobot1234", responce: { uttence_test_heading: [ { buttons: [ { payload: "/my_localities", title: "savings", }, { payload: "/my_localities12333qqqwq", title: "current", }, { payload: "/fruits", title: "platinum", }, ], }, { title: "Test Heading", }, ], }, responce_ID: "6bbb20d6-7f71-408a-a78a-bab39a30016f", responce_name: "uttence_test_heading", updated_BY: "", user_ID: "av1234", }, { created_AT: "Tue, 04 Jan 2022 17:49:36 GMT", created_BY: "avinash", dateTime: "Tue, 04 Jan 2022 17:49:36 GMT", deleted_BY: "", flag: 0, project_ID: "infobot1234", responce: { utter_content: [ { text: "text_title for buttonqwqwq", }, ], }, responce_ID: "81d699ee-3e78-4356-b703-af095d91e36b", responce_name: "utter_txt1234", updated_BY: "", user_ID: "av1234", }, { created_AT: "Thu, 13 Jan 2022 18:06:39 GMT", created_BY: "avinash", dateTime: "Thu, 13 Jan 2022 18:06:39 GMT", deleted_BY: "", flag: 0, project_ID: "infobot1234", responce: { uttence_text_heading: [ { buttons: [ { payload: "/my_localities", title: "savings", }, { payload: "/my_localities12333qqqwq", title: "current", }, { payload: "/test", title: "premium", }, ], }, { title: "Text Heading", }, ], }, responce_ID: "bb6b0005-bbd4-49a1-8b25-58e0768800a1", responce_name: "uttence_text_heading", updated_BY: "", user_ID: "av1234", }, { created_AT: "Thu, 13 Jan 2022 20:13:54 GMT", created_BY: "avinash", dateTime: "Thu, 13 Jan 2022 20:13:54 GMT", deleted_BY: "", flag: 0, project_ID: "infobot1234", responce: { uttence_heading_test: [ { buttons: [ { payload: "/my_localities", title: "savings", }, { payload: "/fruits", title: "current", }, { payload: "/undefined", title: "premium", }, ], }, { title: "heading test", }, ], }, responce_ID: "7aeb2a42-a5f8-464d-832d-47cee4cfdb38", responce_name: "uttence_heading_test", updated_BY: "", user_ID: "av1234", }, ], status_code: 0, }; const findObjectByKey = (array, key) => array.find(item => Object.keys(item).some(k => k === key))?.[key]; const output = data.responce.map(({ responce_ID, responce }) => { const uttence_name = Object.keys(responce)[0]; const arr = responce[uttence_name]; const buttons = findObjectByKey(arr, "buttons")?.map(({ title }) => title).join(" ")?? ""; const title = findObjectByKey(arr, "title")?? ""; const text = findObjectByKey(arr, "text")?? ""; return { responce_ID, uttence_name, buttons, title, text, }; }); console.log(output);

Answer 3

这是根据您提供的数据所需的结果。 在代码中，最好的情况是，它检查您是否有 object 包含文本，然后相应地添加数据。 它也有response_ID

 const data={message:"fetch responces successfully",responce:[{created_AT:"Mon, 03 Jan 2022 17:39:24 GMT",created_BY:"avinash",dateTime:"Mon, 03 Jan 2022 17:39:24 GMT",deleted_BY:"",flag:0,project_ID:"infobot1234",responce:{uttence_test_heading:[{buttons:[{payload:"/my_localities",title:"savings",},{payload:"/my_localities12333qqqwq",title:"current",},{payload:"/fruits",title:"platinum",},],},{title:"Test Heading",},],},responce_ID:"6bbb20d6-7f71-408a-a78a-bab39a30016f",responce_name:"uttence_test_heading",updated_BY:"",user_ID:"av1234",},{created_AT:"Tue, 04 Jan 2022 17:49:36 GMT",created_BY:"avinash",dateTime:"Tue, 04 Jan 2022 17:49:36 GMT",deleted_BY:"",flag:0,project_ID:"infobot1234",responce:{utter_content:[{text:"text_title for buttonqwqwq",},],},responce_ID:"81d699ee-3e78-4356-b703-af095d91e36b",responce_name:"utter_txt1234",updated_BY:"",user_ID:"av1234",},{created_AT:"Thu, 13 Jan 2022 18:06:39 GMT",created_BY:"avinash",dateTime:"Thu, 13 Jan 2022 18:06:39 GMT",deleted_BY:"",flag:0,project_ID:"infobot1234",responce:{uttence_text_heading:[{buttons:[{payload:"/my_localities",title:"savings",},{payload:"/my_localities12333qqqwq",title:"current",},{payload:"/test",title:"premium",},],},{title:"Text Heading",},],},responce_ID:"bb6b0005-bbd4-49a1-8b25-58e0768800a1",responce_name:"uttence_text_heading",updated_BY:"",user_ID:"av1234",},{created_AT:"Thu, 13 Jan 2022 20:13:54 GMT",created_BY:"avinash",dateTime:"Thu, 13 Jan 2022 20:13:54 GMT",deleted_BY:"",flag:0,project_ID:"infobot1234",responce:{uttence_heading_test:[{buttons:[{payload:"/my_localities",title:"savings",},{payload:"/fruits",title:"current",},{payload:"/undefined",title:"premium",},],},{title:"heading test",},],},responce_ID:"7aeb2a42-a5f8-464d-832d-47cee4cfdb38",responce_name:"uttence_heading_test",updated_BY:"",user_ID:"av1234",},],status_code:0,}; let newObject = []; data.responce.forEach((item) => { // We will get each item here now // Assuming object of item.responce will come always const objectName = Object.keys(item.responce)[0]; const dataToPush = { 'responce_ID': item.responce_ID, 'uttence_name': objectName, 'buttons': item.responce[objectName][0].buttons? item.responce[objectName][0].buttons.map(data => data.title): '', 'text': item.responce[objectName].find(data => data.hasOwnProperty('text'))? item.responce[objectName].map(value => value.text)[0]: '' }; // Finally adding the item to the array to give the final output newObject.push(dataToPush); }); console.log(newObject);
