javascript - 获取 json 数组中的一些值

Question

我有一个如下所示的 json。如何检索组“demo”内的信息，而不查看数组，例如: json['data'][0] 我想检索读取第一个值的信息..“group “如果它与演示匹配，则获取所有该组信息。

 {
      "filter": "*",
      "data": [
        {
          "group": "asdasd",
          "enable": 1,
          "timeout": 7,
          "otpMode": 0,
          "company": "cool",
          "signature": "ou yeah",
          "supportPage": "",
          "newsLanguages": [
            0,
            0,
            0,
            0,
            0,
            0,
            0,
            0
          ],
          "newsLanguagesTotal": 0
        },
        {
          "group": "demo",
          "enable": 1,
          "timeout": 7,
          "otpMode": 0,
          "company": "pppppooo",
          "signature": "TTCM",
          "supportPage": "http://www.trz<xa",
          "newsLanguages": [
            0,
            0
          ],
          "newsLanguagesTotal": 0
        }
      ]
    }

我已经很久了:

   let json = JSON.parse(body);
    //console.log(json);
    console.log(json['data'][1]);

哪些访问“演示”

Answer 1

处理每个“数据项”并检查组值。如果匹配，则执行某些操作。

var json = JSON.parse(jsonStr);

for(var i=0;i<json.data.length;i++){
    if(json.data[i].group == "demo"){
        var group = json.data[i];
        // Process the group info
    }
}
