如何从Array获取所有Exit值

Question

console.log(data);

输出：

现在如何使用JQuery或JavaScript从此JSON对象获取所有Exit值？

Answer 1

您只需要映射数组值并返回退出状态

var data = {
  "Status": "OK",
  "Message": "",
  "Data": {
    "LocationId": 1,
    "LocationName": null,
    "LocationData": [

    ],
    "DeviceData": [

    ],
    "AverageData": [
      {
        "Timestamp": "2017-01-01T00:00:00",
        "Data": [
          {
            "Snapshot": false,
