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文档在下面创建了解决方案，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?

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?

字符数组

[  
   {  
      "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"
   }
]

功能代码

 var chars = this.state.characters;

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

 this.setState({characters: chars})

推荐答案

此方法orderBy不会更改输入数组， 您必须将结果分配给您的数组:

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})
