Question

我有一个json数据如下

[{
  "_id": "52cbafc5afcec877d925d116",
  "id": "52",
  "url": "172.34.56.7"
}, {
  "_id": "52c255e5cf0060b8cce84b4a",
  "id": "13",
  "url": "172.18.2.114"
}, {
  "_id": "52cbd018afcec877d925d131",
  "id": "49",
  "url": "172.16.2.120"
}, {
  "_id": "52d60c9eafcec877d925d17a",
  "id": "100",
  "url": "156.45.34.56"
}]

我想打印如下数据。（最后的数据首先出现）

[{
    "_id": "52d60c9eafcec877d925d17a",
    "id": "100",
    "url": "156.45.34.56"
  }, {
    "_id": "52cbd018afcec877d925d131",
    "id": "49",
    "url": "172.16.2.120"
  }, {
    "_id": "52c255e5cf0060b8cce84b4a",
    "id": "13",
    "url": "172.18.2.114"
  },
  [{
    "_id": "52cbafc5afcec877d925d116",
    "id": "52",
    "url": "172.34.56.7"
  }]

实现Comparator，然后用它对Json数组进行排序。

Answer 2

这可以使用

完成

data=data.reverse()

更改json值的顺序
