lodash 两个对象数组的差异

Question

useEffect我的reactJS中有以下代码

\n

const A1 = [{id: 1, nome: "Ruan"}, {id: 2, nome: "Gleison"}]\nconst A2 = [{id: 2, nome: "Gleison"}, {id: 3, nome: "Geraldo"}]\n\nconst results = _.xor(A1,\xc2\xa0A2);\n\nconsole.log(results)\n

\n

lodashis的逻辑_.xor是返回两个数组之间的差异，但是，事实并非如此

\n

我得到的回报如下

\n

0: Object {id: 1, nome: "Ruan"}\n1: Object {id: 2, nome: "Gleison"}\n2: Object {id: 2, nome: "Gleison"}\n3: Object {id: 3, nome: "Geraldo"}\n

\n

我感谢所有提供帮助的努力

Answer 1

您可以使用xorBy来指示用于比较的属性：

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)
