合并两个JS键值数组

问题描述

我需要合并两个JS数组，但是使用concat fn或lodash库我无法做到...

I need to merge two JS arrays, but using concat fn or lodash library i can't do it...

我有两个这样的数组:

[ test2: 'string', test: 'string' ]

[ nome: 'string',test2: 'string', test: 'string' ]

我需要的是这样的结果数组:

And what i need is to have result array like this:

[ test2: 'string', test: 'string', nome: 'string' ]

我该怎么做?我尝试了几种没有成功的方法...

How can i do this? i tried several methods withouth success...

数组concat无效...

Array concat doesn't work...

谢谢

推荐答案

您将数组用作key:value对，但是在Javascript中，数据类型是对象.您的两个输入变成了对象，如下所示:

You're using arrays as a key:value pair, but in Javascript that data type is an object. Your two inputs turned into objects look like this:

{ test2: 'string', test: 'string' }

{ nome: 'string', test2: 'string', test: 'string' }

要合并这两个对象，可以使用ECMAScript 2018 对象传播语法.

To merge these two objects you can use the ECMAScript 2018 Object Spread syntax.

const obj1 = { test2: 'string', test: 'string' };
const obj2 = { nome: 'string',test2: 'string', test: 'string' };
const newObj = {...ob1, ...ob2}

请注意，因为您的对象共享相同的名称和值对，所以只有 test:'string'和 test2:'string'

Note that because your objects share the same name and value pairs, there is only one copy of test:'string' and test2:'string'
