JavaScript對象 - 不能包含訪問鍵 ' - '

可能重複：
How do I reference a javascript object property with a hyphen in it?JavaScript對象 - 不能包含訪問鍵 ' - '

我有以下格式的JSON：

var response1="{" + 
         "\"code\":\"200\"," + 
         "\"requestID\":\"1002\"," + 
         "\"body\":\"[{" + 
         "\\\"author\\\":\\\"sumit\\\"," + 
         "\\\"id\\\":\\\"ABX-002\\\"," + 
         "\\\"title\\\":\\\"How to make Android APK in 2 seconds :)\\\"" + 
         "}," + 
         "" + 
         "{" + 
         "\\\"author\\\":\\\"sumit\\\"," + 
         "\\\"id\\\":\\\"ABX-002\\\"," + 
         "\\\"title\\\":\\\"How to make Android APK in 2 seconds :)\\\"" + 
         "}," + 
         "{"+ 
         "\\\"author\\\":\\\"sumit\\\"," + 
         "\\\"id\\\":\\\"ABX-002\\\"," + 
         "\\\"title\\\":\\\"How to make Android APK in 2 seconds :)\\\"" + 
         "}" + 
         "]\"," + 
         "\"headers\":{\"Server\":\"Apache-Coyote/1.1\"," + 
            "\"Content-Type\":\"text/xml\"," + 
            "\"Content-Length\":\"131\"," + 
            "\"Date\":\"Thu, 06 Sep 2012 09:10:26 GMT\"" + 
            "}" + 
         "}";

我想要解析內容類型密鑰。所以我寫了下面的代碼來解析值：

var jsonResponse = jQuery.parseJSON(response1); 
var contentType = jsonResponse.headers.Content-Type;

我不能夠得到的Content-Type和Content-Length的值。任何幫助，將不勝感激。非常感謝

你爲什麼雙重逃脫身體JSON？ – Bergi

嗨Bergi ...我已經作爲字符串對象的響應，所以我已經添加適當的轉義字符，使其成爲一個適當的JSON字符串。 –

當鑰匙是不是一個合法的道理，你必須使用一個字符串作爲密鑰，並用數組語法：

var contentType = jsonResponse.headers['Content-Type'];

注意：這不是一個「JSON解析」的問題，這是標準的Javascript對象訪問規則。
