Question

我有以下多维数组：

const users = [
  [
    1020,
    "10-FEB-2019",
    "ajd",
    "Mary",
    "jones",
    "a@gmail.com",
    "25 main Lane",
    "brooklyn",
    "NY",
    "11210",
    "5165551212",
    "MEMB",
    "alk",
    "14-FEB-2019",
    93.35
  ],
  [
    1010,
    "08-FEB-2019",
    "dak",
    "Daisy",
    "smith",
    "d@gmail.com",
    "62 stone Drive",
    "brooklyn",
    "NY",
    "11210",
    "5165551212",
    "ADMIN",
    "ERR",
    "19-MAR-2019",
    71.487
  ],
  [
    1000,
    "05-FEB-2019",
    "alk",
    "Arnold",
    "smith",
    "a@gmail.com",
    "62 stone Drive",
    "brooklyn",
    "NY",
    "11210",
    "5165551212",
    "ADMIN",
    "alk",
    "14-FEB-2019",
    203.41
  ]
]

我想按姓氏（索引4）对这个数组进行排序-琼斯，史密斯，史密斯。我尝试了这个var sorted = _.sortBy(users[4]);，但是没有用。

您可以将_.sortBy()或_.orderBy()与要排序的“列”的索引一起使用：

const users = [[1020,"10-FEB-2019","ajd","Mary","jones","a@gmail.com","25 main Lane","brooklyn","NY","11210","5165551212","MEMB","alk","14-FEB-2019",93.35],[1010,"08-FEB-2019","dak","Daisy","smith","d@gmail.com","62 stone Drive","brooklyn","NY","11210","5165551212","ADMIN","ERR","19-MAR-2019",71.487],[1000,"05-FEB-2019","alk","Arnold","smith","a@gmail.com","62 stone Drive","brooklyn","NY","11210","5165551212","ADMIN","alk","14-FEB-2019",203.41]]

const result = _.sortBy(users, 4)

console.log(result)
