如何从打字稿中的对象获取属性

Question

我有一个像这样的对象，我想从中获取“属性”数组并将其存储到新变量中。

obj =  {
        "_id": "5bf7e1be80c05307d06423c2",
        "agentId": "awais",
        "attributes": [ // that array.
            {
                "createdDate": "2018-11-23T11:17:18.771Z",
                "_id": "5bf7e1be80c05307d06423c4",
                "name": "Marketing",
                "description": "Arabic Language Attribute",
                "type": "Boolean",
                "value": "true",
                "usageCount": 0
            },
            {
                "createdDate": "2018-11-23T11:17:18.770Z",
                "_id": "5bf7e1be80c05307d06423c3",
                "name": "English",
                "description": "English Language Attribute",
                "type": "Proficiency",
                "value": "7",
                "usageCount": 0
            }
        ],
        "__v": 0
    }

我不确定我的意思是对的，但是如果您要访问对象并获取数组数据，则可以这样操作：

假设您的json对象保存在var“ jsonObject”变量中，则可以得到如下数组值：

var tempArray = jsonObject['attributes'];
