转换JavaScript对象-JavaScript

如何解决转换JavaScript对象-JavaScript

我有一个简单的JavaScript嵌套对象，如下所示。我不知道会有多少孩子，但这就是我接收到的数据的本质。 如何转换为预期结果？

原始数据嵌套的json

public static Uri getimageContentUri(Context context,File imageFile,String type) {
        if (type != null && type.equals(Constants.IMAGE)) {
            String filePath = imageFile.getAbsolutePath();
            Cursor cursor = context.getContentResolver().query(
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI,new String[]{MediaStore.Images.Media._ID},MediaStore.Images.Media.DATA + "=? ",new String[]{filePath},null);
            if (cursor != null && cursor.movetoFirst()) {
                int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
                cursor.close();
                return Uri.withAppendedpath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,"" + id);
            } else {
                if (imageFile.exists()) {
                    ContentValues values = new ContentValues();
                    values.put(MediaStore.Images.Media.DATA,filePath);
                    return context.getContentResolver().insert(
                            MediaStore.Images.Media.EXTERNAL_CONTENT_URI,values);
                } else {
                    return null;
                }
            }
        } else if (type != null && type.equals(Constants.VIDEO)) {
            String filePath = imageFile.getAbsolutePath();
            Cursor cursor = context.getContentResolver().query(
                    MediaStore.Video.Media.EXTERNAL_CONTENT_URI,new String[]{MediaStore.Video.Media._ID},MediaStore.Video.Media.DATA + "=? ",null);
            if (cursor != null && cursor.movetoFirst()) {
                int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
                cursor.close();
                return Uri.withAppendedpath(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,"" + id);
            } else {
                if (imageFile.exists()) {
                    ContentValues values = new ContentValues();
                    values.put(MediaStore.Video.Media.DATA,filePath);
                    return context.getContentResolver().insert(
                            MediaStore.Video.Media.EXTERNAL_CONTENT_URI,values);
                } else {
                    return null;
                }
            }
        }
        return null;
    }

{
    "work": {
        "children": {
            "abc": {
                
                "label": "Work address","name": "address"
            },"xyz": {
                
                "label": "Work phone","name": "phone"
            },"efg": {
                "children": {
                    "position": {
                        
                        "label": "Work","name": "position"
                    },"employees": {

                        "label": "Number of employees","name": "employees"
                    }
                }
            }
        }
    }
}

我尝试过的是以下代码

{
      work: {
        "address": "","phone": "","details": {
          "position": "","employees": ""
        }
      }
    }

解决方法

您可以使用通用的map函数和递归的transform函数-

const map = (f,t) =>
  Object.fromEntries(Object.entries(t).map(([ k,v ]) => [ k,f(v) ]))

const transform = (t = {}) =>
  t.name 
    ? ""
    : map(transform,t.children || t)

const input =
  {"work":{"children":{"address":{"component":"BaseInput","label":"Work address","name":"address"},"phone":{"component":"BaseInput","label":"Work phone","name":"phone"},"details":{"children":{"position":{"component":"BaseInput","label":"Work position","name":"position"},"employees":{"component":"BaseInput","label":"Number of employees","name":"employees"}}}}}}
  
console.log(transform(input))
