使用 Lodash 按值对对象数组进行排序 [英] use Lodash to sort array of object by value

问题描述

我正在尝试按名称"值对数组进行排序(使用 Lodash).我使用 Lodash 文档来创建下面的解决方案，但是 .orderBy 似乎根本没有任何影响.任何人都可以阐明对数组进行排序的正确方法吗?

字符数组

<预><代码>[{身份证":25，"name":"阿纳金天行者","createdAt":"2017-04-12T12:48:55.000Z","updatedAt":"2017-04-12T12:48:55.000Z"},{身份证":1，"name":"卢克·天行者","createdAt":"2017-04-12T11:25:03.000Z","updatedAt":"2017-04-12T11:25:03.000Z"}]

功能代码

 var chars = this.state.characters;_.orderBy(chars, 'name', 'asc');//使用 Lodash 按 'name' 对数组进行排序this.setState({characters: chars})

解决方案

这个方法 orderBy 不会改变输入数组，您必须将结果分配给您的数组:

var chars = this.state.characters;chars = _.orderBy(chars, ['name'],['asc']);//使用 Lodash 按 'name' 对数组进行排序this.setState({characters: chars})

I am trying to sort an array by 'name' value (using Lodash). I used the Lodash docs to create the solution below however .orderBy doesn't seem to be having any affect at all. Can anyone shed some light on the correct way to sort array?

Chars Array

[  
   {  
      "id":25,
      "name":"Anakin Skywalker",
      "createdAt":"2017-04-12T12:48:55.000Z",
      "updatedAt":"2017-04-12T12:48:55.000Z"
   },
   {  
      "id":1,
      "name":"Luke Skywalker",
      "createdAt":"2017-04-12T11:25:03.000Z",
      "updatedAt":"2017-04-12T11:25:03.000Z"
   }
]

Function Code

 var chars = this.state.characters;

 _.orderBy(chars, 'name', 'asc'); // Use Lodash to sort array by 'name'

 this.setState({characters: chars})

解决方案

This method orderBy does not change the input array, you have to assign the result to your array :

var chars = this.state.characters;

chars = _.orderBy(chars, ['name'],['asc']); // Use Lodash to sort array by 'name'

 this.setState({characters: chars})
