添加到对象而不是覆盖它

我正在使用以下代码

$scope.createAuction = function () {
    var auction = { auction: { langData: {} } };

    if($scope.selected.tab === $scope.infoTabs[0]) {
        Object.assign(auction.auction, {
          type: 'account',
          layout: $scope.selected.description
        });
        if(auction.auction.layout === 1) {
            for(var i = 0, l = $scope.langInput.values.length; i < l; i++) {
                auction.auction.langData[$scope.langInput.values[i].selected] = {
                    name: $scope.inputs.auction_name_account[i + 1]
                };
            }
            for(var i = 0, l = $scope.langInput.values.length; i < l; i++) {
                auction.auction.langData[$scope.langInput.values[i].selected] = {
                    description: 'a'
                }
            }
        }
    }
    console.log(JSON.stringify(auction));
}

,以便将值添加到用户提供的对象中。我正在使用循环,因为用户可以更改输入的数量。

我想要实现的是我的对象看起来像这样:

"auction": {
    "type": "car",
    "layout": 1,
    "langData": {
        "pl": {
            "name": "nazwa aukcji w pl",
            "description": "opis aukcji w pl",
        },
        "eng": {
            "name": "name auction eng",
            "description": "description auction eng",
        },

但是我的代码正在覆盖"pl""eng",所以结果是我只能看到描述。

在第二个循环中,插入description属性,而不是覆盖对象:

for(var i = 0, l = $scope.langInput.values.length; i < l; i++) {
    auction.auction.langData[$scope.langInput.values[i].selected].description = 'a';
}

如果您愿意,还可以组合循环:

for (var i = 0, l = $scope.langInput.values.length; i < l; i++) {
    auction.auction.langData[$scope.langInput.values[i].selected] = {
        name: $scope.inputs.auction_name_account[i + 1],
        description: 'a'
    };
}
