树形结构返回的信息如下。选中时会对应生成 "state": {"selected" : true}，现在我想获取选中时对应的id以及父级的id。怎么优雅的解决呢？？

[
    {
        "id": "514600710075631001",
        "text": "医院管理",
        "state": {
            "selected": true
        },
        "children": [
            {
                "id": "514600710075631106",
                "text": "职称管理",
                "state": {
                    "selected": true
                },
                "children": [
                    {
                        "id": "514600710075631151",
                        "text": "职称列表"
                    }
                ]
            },
            {
                "id": "514600710075631102",
                "text": "科室管理",
                "children": [
                    {
                        "id": "514600710075631121",
                        "text": "科室列表"
                    }
                ]
            }
        ]
    }
]
