將對象差異添加到「正確」位置

Question

我從我的服務器獲取了差異對象，需要將它合併到本地表示中。 所以我需要一種方法來添加當前在原始表示中未定義的對象部分。

例子：

// The serverresponse 
{ 
    "PRIVATE": { 
     "SCREENS": { 
      "WORKSPACE": { 
       "POSTS": { 
        "1363391397125": { 
         "TGT": "1363390641817", 
         "ACN": "position", 
         "TO": [ 
          57.1875, 
          69.21182266009852 
         ] 
        } 
       } 
      } 
     } 
    } 
} 

// This part is similar to my local representation 
{ 
    "PRIVATE": { 
     "SCREENS": { 
      "WORKSPACE": { 
       "POSTS": {} 
      } 
     } 
} 


// So I want to insert this part of the given data at same position inside the local data 
{ 
    "1363391397125": { 
        "TGT": "1363390641817", 
        "ACN": "position", 
        "TO": [ 
          57.1875, 
          69.21182266009852 
         ] 
        } 
} 

有很多不同的部分插入所以我在尋找明確的替代遍歷每個情況下，我都會有。

看到你添加的jQuery的標籤，你可以使用jQuery的extend()方法，類似如下：

// The serverresponse 
var x = { 
    "PRIVATE": { 
     "SCREENS": { 
      "WORKSPACE": { 
       "POSTS": { 
        "1363391397125": { 
         "TGT": "1363390641817", 
          "ACN": "position", 
          "TO": [ 
         57.1875, 
         69.21182266009852] 
        } 
       } 
      } 
     } 
    } 
}; 

// This part is similar to my local representation 
var y = { 
    "PRIVATE": { 
     "SCREENS": { 
      "WORKSPACE": { 
       "POSTS": {} 
      } 
     } 
    } 
}; 

// merges x into y 
$.extend(y, x); 

// use $.extend(x, y); if you intended it to be the other way around.
