不確定關於定義錯誤

Question

我給了一個大數組，然後我必須將數據傳輸到一個不同的數組，取決於類型是「客戶」，「商店」還是「地址」，但我得到以下錯誤和我;米不知道爲什麼

/* 
Exception: ReferenceError: store is not defined 
CustomerDB.insertData@Scratchpad/1:56:17 
@Scratchpad/1:105:1 
*/ 


var allData = [ 
{type:"store", data:{store_id: 297, name: "Scotiabank - Main Branch",  address_id: 1023}}, 
{type:"store", data:{store_id: 614, name: "Scotiabank - Hamilton", address_id: 1984}}, 
{type:"customer", data:{customer_id: 24, store_id:614, first_name: "Jonathan", last_name: "Pym", email: "jjpym@yahoo.ca", address_id: 1611, add_date: null}}, 
{type:"customer", data:{customer_id: 36, store_id:193, first_name: "Kaitlyn", last_name: "Adams", email: "katy38@hotmail.com", address_id: 5464, add_date: null}}, 
{type:"customer", data:{customer_id: 73, store_id:297, first_name: "Melissa", last_name: "Bennett", email: "mbennett@gmail.com", address_id: 4536, add_date: null}},   
{type:"address", data:{address_id: 1023, address: "2895 Yonge St.",  city:"Toronto", province:"ON", postal_code:"L4C02G"}}, 
{type:"address", data:{address_id: 1984, address: "3611 Main St. West", city:"Hamilton", province:"ON", postal_code:"R5O8H5"}}, 
{type:"address", data:{address_id: 1757, address: "1177 Ontario St. Unit 8", city:"Mississauga", province:"ON", postal_code:"L9H6B3"}}, 
{type:"address", data:{address_id: 4536, address: "3945 John St.", city: "Ajax", province: "ON", postal_code: "L7M4T9"}}, 

var CustomerDB = 
{ 
    customer:[], 
    address:[], 
    store:[], 

    insertData:function (allData) 
    { 
     for (var i = 0; i < allData.length; i++) 
     {  
     if (allData[i].type == "store") 
      { 
      store[i].push(allData[i].store_id, allData[i].name, allData[i].address_id); 

      } 
     else if (allData[i].type == "customer") 
      { 
      this[i].add_date = new Date(); 
      customer[i].push(allData[i].customer_id, allData[i].store_id, allData[i].first_name, allData[i].last_name, allData[i].email, allData[i].addess_id, allData[i].add_date); 
      } 
     else if (allData[i].type == "address") 
      { 
      address[i].push(allData[i].address_id, allData[i].address, allData[i].city, allData[i].province, allData[i].cpostal_code); 
      } 
     } 
    } 
} 
CustomerDB.insertData(allData); 

Answer 1

雖然我仍然認爲https://stackoverflow.com/a/42182030/6647153是最好的答案。但是，在這裏你去：

1. 這是主要的問題：你必須使用this關鍵字來訪問屬性（陣列）store，cutomer和adress。
2. 推送到數組時，不需要使用下標。
3. 您必須將數據包裝在對象中才能將事物分組。 （這裏我用的是原來的對象）

試試這個：如果你要複製的對象

insertData: function (allData) { 
    for (var i = 0; i < allData.length; i++) {  
     if (allData[i].type == "store") { 
      this.store.push(allData[i]); 
     } 
     else if (allData[i].type == "customer") { 
      allData[i].add_date = new Date(); 
      this.customer.push(allData[i]); 
     } 
     else if (allData[i].type == "address") { 
      this.adress(allData[i]); 
     } 
    } 
} 

，而不是推原，然後使用此功能是這樣的：

function clone(obj) { 
    var newObj = {}; 
    for(var key in obj) 
     newObj[key] = obj[key]; 
    return newObj; 
} 

而且這樣稱呼：

insertData: function (allData) { 
    for (var i = 0; i < allData.length; i++) { 
     var o = clone(allData[i]); 
     var type = o.type; 
     delete o.type; // to remove the type if you want 
     if (type == "store") { 
      this.store.push(o); 
     } 
     else if (type == "customer") { 
      var o.add_date = new Date(); 
      this.customer.push(o); 
     } 
     else if (type == "address") { 
      this.adress(o); 
     } 
    } 
}
