我有一個用例來建立一個包含動態資料（包括標題名稱）的表。我嘗試了多種方法從API回應中重建數組，但仍然無法開發它。
從回應接收陣列如下
[ { "category": "Emergency services", "code": "RMY 90", "limit": "9032", "OT": "4124" }, { "category": "Pediatrician", "code": "RMY 80", "limit": "1232", "OT": "9412" }, { "category": "Neurology", "code": "RMY 70", "limit": "6423", "OT": "7312" } ]
網格預期陣列
[ { "item": "Block Code", "Emergency services": "RMY 90", "Pediatrician": "RMY 80", "Neurology": "RMY 70" }, { "item": "Total Capacity", "Emergency services": "9032", "Pediatrician": "1232", "Neurology": "6423" }, { "item": "OT Capacity", "Emergency services": "4124", "Pediatrician": "9412", "Neurology": "7312" } ]
表格範例
我嘗試過使用 Object.keys() 和 map 但無法正確建構陣列。由於程式碼位於客戶端系統中，我無法共用它。請幫我重建數組。
我的程式碼是
const rowList = ["Block Code", "Total Capacity", "OT Capacity"]; let arr = []; const dumming = rowList?.forEach(item => { for (const [key, object] of Object.entries(responseData)) { let x = []; Object.keys(object)?.forEach(item => { x.push(object[item]); }); // console.log('rrrr', x); } let val = responseData.map((ned, index) => { let x = {}; Object.keys(object)?.forEach(item => { x = ned[item] }); // let cor = Object.entries(ned).map(([key, leaf]) => key+leaf); return { id: `${ index }-${ item }`, name: item, ...x }; }); arr.push(val); }); console.log(arr);
我不確定這是否正確。陷入困境
使用rowList 的想法很好，但它假設輸入物件中存在一些關鍵順序（當您稍後需要將資料與每個標籤關聯時），這通常是一個壞主意依賴於普通物件中的某些順序。
但是，您的
rowList沒有任何作用：儘管您迭代它，但您的程式碼從不使用item（它定義了其他item變量）。其次，
.map回呼中有一個未知變數object。我不懂為什麼你會產生一個有
id和name鍵的對象，並產生格式為${ index }-${ item } 的字串因為這與您問題中的任何內容都不符。以下是我建議的做法：
const responseData = [{"category": "Emergency services","code": "RMY 90","limit": "9032","OT": "4124"},{"category": "Pediatrician","code": "RMY 80","limit": "1232","OT": "9412"},{"category": "Neurology","code": "RMY 70","limit": "6423","OT": "7312"}]; const rowList = [["code", "Block Code"], ["limit", "Total Capacity"], ["OT", "OT Capacity"]]; const result = rowList.map(([key, item]) => ({ item, ...Object.fromEntries(responseData.map((obj) => [obj.category, obj[key]])) })); console.log(result);
