Question

我有以下JSON：

{
"code": 201,
"data": {
    "type": "Agent",
    "id": {
        "@type": "Client",
        "@id": "88",
        "title": "Ing.",
        "titleAfter": null,
        "name": "Ján",
        "surname": "Kašperan",
        "idNumber": "8706229411",
        "dateOfBirth": null,
        "idCardNumber": "OP12345",
        "idCardExpirationDate": null,
        "idCardType": {
            "@type": "IdCardType",
            "@id": 1,
            "name": "id_card_type.id_card",
            "shortName": "OP"
        },
        "type": 1
    }
}
}

我想写一个JSON路径表达式，以便我想得到＆＃34; @ id＆＃34; 的价值：＆＃34; 88＆＃34;，。

我的JSON路径不起作用：$ .data.id。@ id

由于不允许@，因此请通过字符串属性名称访问它。有关属性访问器的更多信息，请参见MDN

var json = {
  "code": 201,
  "data": {
    "type": "Agent",
    "id": {
      "@type": "Client",
      "@id": "88",
      "title": "Ing.",
      "titleAfter": null,
      "name": "Ján",
      "surname": "Kašperan",
      "idNumber": "8706229411",
      "dateOfBirth": null,
      "idCardNumber": "OP12345",
      "idCardExpirationDate": null,
      "idCardType": {
        "@type": "IdCardType",
        "@id": 1,
        "name": "id_card_type.id_card",
        "shortName": "OP"
      },
      "type": 1
    }
  }
}
console.log(json.data.id["@id"])
