如何在 JSON.stringify() 之后获取特定值

Question

这是console.log 中显示的数据。

{"data":
    [
        {
            "CloserName":null,
            "agent_id":"10807",
            "AgentName":"TEST",
            "SurveyDate":"02/02/2018 02:18:46 AM",
            "SurveyName":"Ruth  ",
            "state":"West Bengal",
            "phone":"9836969715",
            "status":"Approved",
            "verification_progress":"Pending",
            "survey_id":"1",
            "rejection_remarks":"aa",
            "tl_remarks":"Pending"
        }
    ],
    "count":1
}

谁能帮我显示单个值（即survey_id）？我只是想拿那个survey_id

这是一个例子：

var json = {  
   "data":[  
      {  
         "CloserName":null,
         "agent_id":"10807",
         "AgentName":"TEST",
         "SurveyDate":"02/02/2018 02:18:46 AM",
         "SurveyName":"Ruth ",
         "state":"West Bengal",
         "phone":"9836969715",
         "status":"Approved",
         "verification_progress":"Pending",
         "survey_id":"1",
         "rejection_remarks":"aa",
         "tl_remarks":"Pending"
      }
   ],
   "count":1
}

// get first id
var id = json.data[0].survey_id
console.log(id)

// get all ids
var ids = json.data.map(x => x.survey_id)
console.log(ids)

如果 JSON 已字符串化，JSON.parse(jsonStr)请先调用。
