循環遍歷和打印嵌套的JSON對象成員

Question

我已經成功返回了要搜索的對象（商店），但是現在我想遍歷服務員數組並為商店打印服務員。 我不能使用jQuery $ each（）進行迭代。 我能做什么？ 謝謝，謝謝您的協助。

totals.js（我的服務）

export const baseUrl = '/src/areas/store-totals/services/tender-total-data.json';
export const all = args =>

  // http.post.standard(baseUrl + 'orders/tenderTotals', {}, args);
  http.get(baseUrl).
  then(function onSuccess(response) { 
    console.log("The response is :" , response);        
  }).
  catch(function onError(response) {
   console.log(response);
  });

投標總data.json

Answer 1

如果要獲取特定商店的服務員，可以使用array.find，如下所示，

 let data ={ "stores": [ { "storeName": "Master Bistro", "storeId": "3046", "attendants": [ { "attendantName": "Janis Joplin", "attendantId": "9784526", "total": 2000, "tenderTotal": { "Cash": 500, "TC": 0, "UOD": 500, "MC": 250, "VI": 250, "AX": 250, "DI": 250, "JC": 0, "DC": 0, "UOP": 0, "GN": 0, "UOGC": 0, "HOTEL": 0, "NCTNCG": 0 } }, { "attendantName": "David Bowie", "attendantId": "2589456", "total": 14675, "tenderTotal": { "Cash": 175, "TC": 0, "UOD": 100, "MC": 9500, "VI": 3500, "AX": 550, "DI": 850, "JC": 0, "DC": 0, "UOP": 0, "GN": 0, "UOGC": 0, "HOTEL": 0, "NCTNCG": 0 } }, { "attendantName": "Michael Jackson", "attendantId": "5478264", "total": 15599, "tenderTotal": { "Cash": 250, "TC": 0, "UOD": 80, "MC": 5624, "VI": 6895, "AX": 2500, "DI": 250, "JC": 0, "DC": 0, "UOP": 0, "GN": 0, "UOGC": 0, "HOTEL": 0, "NCTNCG": 0 } } ], "message": "Store totals for 08/20/2018", "date": "08/20/2018" }, { "storeName": "The Master Marketplace", "storeId": "3047", "attendants": [ { "attendantName": "Dirk Novitski", "attendantId": "9784527", "total": 2000, "tenderTotal": { "Cash": 500, "TC": 0, "UOD": 500, "MC": 250, "VI": 250, "AX": 250, "DI": 250, "JC": 0, "DC": 0, "UOP": 0, "GN": 0, "UOGC": 0, "HOTEL": 0, "NCTNCG": 0 } }, { "attendantName": "Carmello Anthony", "attendantId": "2589458", "total": 14675, "tenderTotal": { "Cash": 175, "TC": 0, "UOD": 100, "MC": 9500, "VI": 3500, "AX": 550, "DI": 850, "JC": 0, "DC": 0, "UOP": 0, "GN": 0, "UOGC": 0, "HOTEL": 0, "NCTNCG": 0 } }, { "attendantName": "Stevie Wonder", "attendantId": "5478266", "total": 15599, "tenderTotal": { "Cash": 250, "TC": 0, "UOD": 80, "MC": 5624, "VI": 6895, "AX": 2500, "DI": 250, "JC": 0, "DC": 0, "UOP": 0, "GN": 0, "UOGC": 0, "HOTEL": 0, "NCTNCG": 0 } } ], "message": "Store totals for 08/22/2018", "date": "08/21/2018" } ] }; let attendants = data.stores.find(store=>store.storeId == 3047).attendants; attendants.forEach( (element) => { console.log(element); }); 

Answer 2

要迭代數組元素，可以使用諸如map或forEach之類的函數。 如果使用map，則迭代邏輯將類似於：

attendants.map((item) => {
 console.log(item);
});
