获取非索引的数组属性

我有一个数组,它附加了如下属性:

    let arVar = [[{a: 1, b:2},{c:3, d:4}, {e:5}]]
     arVar.item_id = "9";
     arVar.type_id = "1";

v 是 arVar ledgerTransactionsArray . 具有我需要的属性,以便我可以将其添加到新的 v .

v 可以拥有或是否会拥有任何财产

arVar.type_id 和 arVar.item_id 这样我就可以将它附加到另一个数组:

$scope.ledgerTransactionsArray = $scope.ledgerTransactionsArray.map(function(v) {
//v is the array with properties that i need to attach to new v
//v has item_id, type_id
      if (Array.isArray(v)) {
        console.log(v, "typeidcheck");
        v = v.map(function(subArrayObj) {

          for (let key in subArrayObj) {
            if (
              key == "credit_amount" || key == "debit_amount" ||
              key == "credit_total" || key == "debit_total"
            ) {
              if (subArrayObj[key]) {
                subArrayObj[key] = parseFloat(subArrayObj[key]).toLocaleString(undefined, {
                  maximumFractionDigits: 2,
                  minimumFractionDigits: 2
                });

              }
            }
          }

          return subArrayObj;
        })
      }
    })
