在对象中创建对象数组 - Node.js

Question

在下面的代码中，'info'对象具有描述，数量，值。如何将它们作为数组（Indo属性）。如何在角码中检索。

details.customsDetail.itemDetails = { 
        currency : "2000USD", 
        weight : "lbs", 
        info : {       
         description : "descr", 
         quantity : "2", 
         value : "124",    

        } 

      }; 

Answer 1

你的意思是，indo属性作为数组的对象吗？

details.customsDetail.itemDetails = { 
        currency : "2000USD", 
        weight : "lbs", 
        info : [{       // How to give this in a array. 
         description : "descr", 
         quantity : "2", 
         value : "124",    

        }] 

      };

您可以将对象分配给变量，稍后可以将其推送到数组。

var backUp = angular.copy($scope.details.customsDetail.itemDetails.info); 

$scope.details.customsDetail.itemDetails.info = []; 
$scope.details.customsDetail.itemDetails.info.push(backUp); 

console.log($scope.details.customsDetail.itemDetails) 

angular.module("app",[]) 
 
.controller("ctrl",function($scope){ 
 
$scope.details = {"customsDetail":{"itemDetails":{}}}; 
 

 
$scope.details.customsDetail.itemDetails = { 
 
     currency : "2000USD", 
 
     weight : "lbs", 
 
     info : {// How to give this in a array. 
 
      description : "descr", 
 
      quantity : "2", 
 
      value : "124",    
 

 
     } 
 

 
    }; 
 

 
var backUp = angular.copy($scope.details.customsDetail.itemDetails.info); 
 

 
$scope.details.customsDetail.itemDetails.info = []; 
 
$scope.details.customsDetail.itemDetails.info.push(backUp); 
 

 
console.log($scope.details.customsDetail.itemDetails) 
 
    
 
})
