javascript - 扩展/合并对象

Question

我目前正在尝试使用 AngularJS 扩展/推送/合并一个对象，我的问题是，当我扩展时，它添加一个索引为 0 的对象，但我无法再添加，因为它们都获得相同的索引 0

//Original Object
{ "groups": { 
            "1": { "id": "1", "name": "object1"},
            "2": { "id": "2", "name": "object2"}
            }
}

//After running function
{ "groups": { 
            "0": { "id": "1", "name": "object0"}, //This is the new object no more can then be added
            "1": { "id": "1", "name": "object1"},
            "2": { "id": "2", "name": "object2"}
            }
}

//What I want
{ "groups": {                
            "1": { "id": "1", "name": "object1"},
            "2": { "id": "2", "name": "object2"},
            "3": { "id": "3", "name": "object3"},
            "4": { "id": "4", "name": "object4"} // etc
            }
}

我目前正在使用这个:

$scope.addGroup = function () {

    angular.extend($scope.audit.groups,[
        {
                "name": "",
                "questions": []
            }
        ]);
}

PHP 对象目前正在像这样构建，如果重组这将有助于我非常愿意这样做。

public function getAllQuestionGroupsByAuditIdArray($id) {

    $questions = new Question();
    foreach ($this->getAllQuestionGroupsByAuditId($id) AS $key => $group) {

        $QuestionGroups[$key] = array(
            "id" => $group['id'],
            "name" => $group['name'],
            "questions" => $questions->getQuestionsByGroupIdArray($group['id'])
        );
    }


    return $QuestionGroups;
}

$this->response = array(
        "name" => $auditData['name'],
        "groups" => $questionGroups->getAllQuestionGroupsByAuditIdArray($id),
    );
return print_r(json_encode($this->response));

在 PHP 中，我们可以更新响应以返回非关联数组或组，如下所示:

$QuestionGroups = array();
foreach ($this->getAllQuestionGroupsByAuditId($id) AS $key => $group) {
    $QuestionGroups[] = array(
        "id" => $group['id'],
        "name" => $group['name'],
        "questions" => $questions->getQuestionsByGroupIdArray($group['id'])
    );
}

当转换为 JSON 时，这会将groups 作为对象数组而不是对象的对象返回。

然后，您可以简单地使用 .push() 将更多组附加到 groups 数组中。
