Question

我有一个像这样开始的json。我可以毫无问题地访问用户，声明和相关的第一级数据。我正在尝试在ClaimResponse中访问特定变量的数据（即User.id = 3）。我尝试了

x.ClaimResponse[Userid].id

的变体，没有运气。关于我如何获得这些数据的任何直接想法？

{
"data": [
    {
        "User": {
            "score": "272",
            "id": "3"},
        "Claim": {

Answer 1

[]运算符用于根据数组中的索引获取数据，例如，如果ClaimResponse [0]获得id为4的用户

Answer 2

你可以在使用返回数组的关键ClaimResponse获取数据后为数组运行for循环。

喜欢

public static JSONObject ObjectWithIdandReponse(int _id,JSONArray responseArray) {
    for (JSONObject Obj in responseArray)
    {
     if(Obj.id==_id)
     return Obj;
    }
}

Make方法返回JSON Obj并将参数作为用户ID和声明数组传递

Answer 3

您是否尝试使用特定ID获取特定的ClaimResponse？如果是这样，试试这个：

var arr = x.ClaimResponse,
    userId = "3", //Set this to the uid you want
    length = arr.length,
    claim = null; //This variable stores the correct claim

for (var i = 0; i < length; i++) {
  claim = arr[i];
  if (claim.id === userId) {
    break;
  }
}

基于变量获取json数组的值
