带破折号的两个对象数组的区别

本文介绍了带破折号的两个对象数组的区别的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在reactJS的 useEffect 中有以下代码

I have the following code inside my useEffect in reactJS

const A1 = [{id: 1, nome: "Ruan"}, {id: 2, nome: "Gleison"}] const A2 = [{id: 2, nome: "Gleison"}, {id: 3, nome: "Geraldo"}] const results = _.xor(A1, A2); console.log(results)

lodash 的逻辑是 _.xor 是要返回两个数组之间的差，但是，这不是正在发生的事情

The logic of lodash is _.xor is to return the difference between the two arrays, however, that is not what is happening

我得到的回报如下

0: Object {id: 1, nome: "Ruan"} 1: Object {id: 2, nome: "Gleison"} 2: Object {id: 2, nome: "Gleison"} 3: Object {id: 3, nome: "Geraldo"}

我非常感谢您提供的所有帮助

推荐答案

您可以使用 xorBy 表示用于比较的属性:

You can use xorBy to indicate a property used for comparison:

const A1 = [{id: 1, nome: "Ruan"}, {id: 2, nome: "Gleison"}] const A2 = [{id: 2, nome: "Gleison"}, {id: 3, nome: "Geraldo"}] const results = _.xorBy(A1, A2, 'id'); // or 'nome' console.log(results)
