                $scope.users = [];
                $scope.user = { items : [] , attributes : [] };
                $scope.editMode = false;

                $scope.addItem = function (index) {

                        $scope.user.items.push({
                            Name: $scope.newItemName,
                            Value: $scope.newItemValue
                        });
                    };

                 $scope.deleteItem = function (index) {
                         $scope.user.items.splice(index, 1);
                     };

}

                                                    </td>
                                                </tr>
                                            </table>

                                        </div>
                                    </ul>
                                </div>

我怀疑的是,每当我点击addItem时,它将被存储为Name:“xxx”,Value:“yyy”,但我希望它存储为xxx:yyy。有没有办法做到这一点。我是角度js的新手。请帮我。谢谢

尝试在addItem方法中使用此代码:

$scope.addItem = function (index) {
    var newItem = {};
    newItem[$scope.newItemName] = $scope.newItemValue;
    $scope.user.items.push(newItem);
};

在此代码中,您首先为新项目创建一个对象,然后从newItemName创建该属性,并为其指定一个来自字段newItemValue的值。然后你把它推到一个数组。

这种方法的一个问题是像<p>{{item.Name}}</p>这样的绑定不起作用,因为没有名为Name的属性了。我不知道你为什么要以你描述的格式存储数据,但是为了使旧的绑定工作,你也可以使用旧的属性:

$scope.addItem = function (index) {
    var newItem = {Name: $scope.newItemName, Value: $scope.newItemValue };
    newItem[$scope.newItemName] = $scope.newItemValue;
    $scope.user.items.push(newItem);
};

使用地图代替项目列表:

$scope.user = { items : {} , attributes : [] };

$scope.user.items[$scope.newItemName] = $scope.newItemValue;
