Angular 2如何將對象數組放入另一個對象數組

Question

所以我有2 Arrays （總是等於index ）：

A: [
{name: Jhon1}
{name: Jhon2}
{name: Jhon3}
]

B: [
{lastName: Pom1}
{lastName: Pom2}
{lastName: Pom3}
]

合並后的預期結果：

A: [
   {name: Jhon1, lastName: Pom1}
   {name: Jhon2, lastName: Pom2}
   {name: Jhon3, lastName: Pom3}
]

Concat方法只是將整個數組合並為一個這樣的數組：

  A: [
    {name: Jhon1}
    {name: Jhon2}
    {name: Jhon3}
    {lastName: Pom1}
    {lastName: Pom2}
    {lastName: Pom3}
    ]

我正在嘗試的我自己的功能。 下面有兩個數組： this.prices和this.search.favoriteItems ，然后我想像以前描述的那樣合並：

showProducts(){
   for(let i of this.localStorageArray){
    let id = localStorage.getItem(i);
    this.search.getProductsById(id).subscribe
    ((data: any) => {
     this.prices.push(data.lowestPrices.Amazon);
     this.search.favoriteItems.push(data);  
   //something here to merge this.prices and this.search
    });

  }
  }

您可以將.map()與對象銷毀一起使用：

 let arr1 = [{name: 'Jhon1'}, {name: 'Jhon2'}, {name: 'Jhon3'}], arr2 = [{lastName: 'Pom1'}, {lastName: 'Pom2'}, {lastName: 'Pom3'}]; let zip = (a1, a2) => a1.map((o, i) => ({...o, ...a2[i]})); console.log(zip(arr1, arr2)); 

 .as-console-wrapper { max-height: 100% !important; top: 0; }
