我訪問使用JavaScript這個對象。 Id喜歡訪問此LocalizedLabel中的「標籤」的值。

"Label":{ 
       "LocalizedLabels":[ 
       { 
        "Label":"Active","LanguageCode":1033,"IsManaged":true,"MetadataId":"4754c2fa- 
2241-db11-898a-0007e9e17ebd","HasChanged":null 
        } 
}

開始於任何JavaScript對象，您已經將JSON解析爲.. –

然後什麼?????? –

你是怎麼「用JavaScript來解析它的？」 – Rafael

訪問Javascript對象中的不同圖層是非常直接的，一旦你得到了把戲。基本上，當你想要更深入一個對象時，你使用「。」來表示。其次是密鑰名稱。例如：

object = {"key1": { "key2": "some value"}} 
value = object.key1.key2 //returns "some value"

這將返回與該密鑰關聯的值。如果該值是另一個對象，則可以迭代該過程。如果該值是一個數組，那麼就像在任何其他數組上一樣操作它。

再加上通常數組訪問技術：

object = {"key1": 
      { "key2": 
       [ 
        {"key3": "some value"}, 
        {"key3": "another value"} 
       ] 
     }} 
list = object.key1.key2 // returns "[ {"key3": "some value"},{"key3": "another attribute"}]" 

listElement = object.key1.key2[0] // return "{"key3": "some value"}" 

value = object.key1.key2[0].key3 // returns "some value" 

otherValue = object.key1.key2[1].key3 // returns "another value"

等

編輯：正如在下面的評論指出，JSON是一個簡單的格式化，本身不是一個數據類型。你想知道的是這裏是如何操作javascript對象和數組。（換句話說，JSON是一種將對象和/或數組作爲字符串的語法方式正確的javascript，有關更多詳細信息，請參閱here）

請注意，此答案中沒有JSON，只是嵌套的對象/數組。 – nnnnnn

好吧，我的錯誤。編輯我的答案，謝謝你指出。 –
