使用现有属性值添加新的JSON属性

Question

我有一个JSON序列化数据文件，看起来像这样：

{
    "name":"Store",
    "children":[
        {
            "name":"Store 1",
            "children":[
                {
                    "name":"collection 1",
                    "description":"collection 1",
                    "children":[
                        {
                            "name":"Products",
                            "description":"Products",
                            "children":[
                                {
                                    "name":"Product 1",
                                    "description":"Product 1"
                                }
                            ]
                        }
                    ]
                }
            ],
            "description":"category 1"
        },
        {
            "name":"Store 2"
        }
    ]
}

对于具有name属性的对象，我想添加一个title，其值与name属性的值相同。以下是我尝试将JSON转换为的内容：

{
    "name":"Store",
    "title":"Store",
    "children":[
        {
            "name":"Store 1",
            "title":"Store 1",
            "children":[
                {
                    "name":"collection 1",
                    "title":"collection 1",
                    "description":"collection 1",
                    "children":[
                        {
                            "name":"Products",
                            "title":"Products",
                            "description":"Products",
                            "children":[
                                {
                                    "name":"Product 1",
                                    "title":"Product 1",
                                    "description":"Product 1"
                                }
                            ]
                        }
                    ]
                }
            ],
            "description":"category 1"
        },
        {
            "name":"Store 2",
            "title":"Store 2"
        }
    ]
}

我们可以使用JSON.Parse解析Json并使用递归为所有子代添加标题，如下所示：>

function Recursion(items) {
  items["title"] = items["name"]
  if (items["children"] != undefined) {
    items["children"].forEach(element => {
      element = Recursion(element)
    });
  }
  return items
}



 var text = '{"name":"Store","children":[{"name":"Store 1","children":[{"name":"collection 1","description":"collection 1","children":[{"name":"Products","description":"Products","children":[{"name":"Product 1","description":"Product 1"}]}]}],"description":"category 1"},{"name":"Store 2"}]}';
  var item = JSON.parse(text);
  item = Recursion(item);
