Question

所以我可能会过度思考这个，但我有一个JSON数组，其中包含多层嵌套JSON对象，如下所示：

var OldJSON =  
    {  
   "data":{  
      "shifts":{  
         "data":[  
            {  
               "id":1234,
               "entry_time":"2012-06-11 16:06:04",
               "attendance_id":1
            },
            {  
               "id":4321,
               "entry_time":"2014-07-23 17:29:04",
               "attendance_id":2
            }
         ]
      },
      "sites":{  
         "data":[  
            {  
               "id":4321,
               "name":"John Doe",
               "type":"field",
               "bases":{  
                  "data":[  
                     {  
                        "id":1234,
                        "type":"field",
                        "active":false
                     },
                     {  
                        "id":4321,
                        "type":"field",
                        "active":true
                     }
                  ]
               }
            },
            {  
               "id":1234,
               "name":"Jill Doe",
               "type":"field",
               "bases":{  
                  "data":[  
                     {  
                        "id":1234,
                        "type":"field",
                        "active":false
                     },
                     {  
                        "id":4321,
                        "type":"field",
                        "active":true
                     }
                  ]
               }
            }
         ]
      }
   }
}

我想要做的是将'base'对象从'sites'对象中分离出来并重新组织JSON，使它看起来像这样：

var NewJSON = 
{  
   "data":{  
      "shifts":{  
         "data":[  
            {  
               "id":1234,
               "entry_time":"2012-06-11 16:06:04",
               "attendance_id":1
            },
            {  
               "id":4321,
               "entry_time":"2014-07-23 17:29:04",
               "attendance_id":2
            }
         ]
      },
      "sites":{  
         "data":[  
            {  
               "id":4321,
               "name":"John Doe",
               "type":"field"
            },
            {  
               "id":1234,
               "name":"Jill Doe",
               "type":"field"
            }
         ]
      },
      "bases":{  
         "data":[  
            {  
               "id":1234,
               "type":"field",
               "active":false
            },
            {  
               "id":4321,
               "type":"field",
               "active":true
            }
         ]
      }
   }
}

我在项目中使用Javascript和Angular以及下划线。理想情况下，解决方案将利用这三者之一。我想出来的所有东西看起来都很难看，所以我想知道是否有一种简单的方法可以做我喜欢的这样的事情。

这段代码怎么样，太丑了？

var data = JSON.parse(/*Your JSON */).data;
var bases = [];
var i;
var sites = data.sites.data;
var len = sites.length;

for (i = 0; i < len; i++) {
    var site = sites[i];
    var base = site.data.bases;

    bases.push(base.date);

    delete site.data.bases;
}

data.bases = {data : Array.prototype.concat.apply([], bases) };
