如何使用 javascript 访问此 JSON 字符串中的响应/响应 ID？

Question

嗨，我正在使用parsejson解析此JSON字符串：

json = [
  {
    "Answers": [
      {
        "Responses": [
        ],
        "AnswerID": 1,
        "AnswerText": "Green"
      },
      {
        "Responses": [
          {
            "ResponseID": 1,
            "RespondingUser": null,
            "ResponseDate": "/Date(1351694241577)/"
          },
          {
            "ResponseID": 2,
            "RespondingUser": null,
            "ResponseDate": "/Date(1351694245093)/"
          }
        ],
        "AnswerID": 2,
        "AnswerText": "Blue"
      }
    ],
    "QuestionID": 1,
    "QuestionText": "Favourite colour?",
    "ClosingDate": "/Date(1351953058527)/",
    "AskingUser": null
  }
]
var result = jQuery.parseJSON(json);

但是，现在如何从"结果"中获得响应/响应ID？任何帮助将不胜感激！

Answer 1

[] = array

{} =对象

您有一个数组，丢失了包装方括号。

alert（json.answers [0] .answertext）=" green"

Answer 2

您应该能够使用for-in-in循环：

 for (i in result[0].Answers)
 {
    // do something with result[0].Answers[i].Responses
 }

这是您要寻找的吗？

Answer 3

for (var a in result[0].Answers) {
    result[0].Answers[a].AnswerID // Do something with it.
}
