如何向数组内的现有对象添加属性

Question

例如这是原始数组[ {name:xyz,id:123 }, {name:abc,id:232},] 现在这是另一个数组[ {value:'anything'}, {value:'anything12312'}]现在在新数组或原始数组中，输出应该是这样的[ {value:'anything',name:xyz,id:123}, {value:'anything12312', name:abc,id:232}}]我怎样才能实现这个目标

Answer 1

你的意思是这样？

使用地图、索引和传播作为：

let a = [

 {name:"xyz",id:123 },

 {name:"abc",id:232},

]

let b = [

 {value:'anyrhing'},

 {value:'anything12312'}

]

let res = a.map((el,idx)=> ({...el,...b[idx]}));

console.log(res)

Answer 2

使用对象解构。

const arr1 = [

 {name:'xyz',id:123 },

 {name:'abc',id:232},

] 

const arr2 = [

 {value:'anyrhing'},

 {value:'anything12312'}

]

const arr3 = [];

for(let i=0;i<arr1.length;i++)

  arr3.push({...arr2[i],...arr1[i]});

Answer 3

A1=[

    {name:"xyz",id:123 },

    {name:"abc",id:232},

   ];

A2=[

    {value:'anyrhing'},

    {value:'anything12312'}

   ];

obj1={

    ...A2[0],

    ...A1[0]}

//another method to merge objects

obj2=Object.assign(A2[1],A1[1]);

//The result you needed

A3=[obj1,obj2];
