我访问使用JavaScript这个对象。 Id喜欢访问此LocalizedLabel中的“标签”的值。

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

开始于任何JavaScript对象，您已经将JSON解析为.. –

然后什么?????? –

你是怎么“用JavaScript来解析它的？” – Rafael

访问Javascript对象中的不同图层是非常直接的，一旦你得到了把戏。基本上，当你想要更深入一个对象时，你使用“。”来表示。其次是密钥名称。例如：

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

这将返回与该密钥关联的值。如果该值是另一个对象，则可以迭代该过程。如果该值是一个数组，那么就像在任何其他数组上一样操作它。

再加上通常数组访问技术：

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

编辑：正如在下面的评论指出，JSON是一个简单的格式化，本身不是一个数据类型。你想知道的是这里是如何操作javascript对象和数组。（换句话说，JSON是一种将对象和/或数组作为字符串的语法方式正确的javascript，有关更多详细信息，请参阅here）

请注意，此答案中没有JSON，只是嵌套的对象/数组。 – nnnnnn

好吧，我的错误。编辑我的答案，谢谢你指出。 –
