Question

我从API获得以下回报：

{
"0": {
    "lat": "-30.02897288697400000",
    "lng": "-51.22800440001900000"
},
"1": {
    "lat": "-30.02879088697400000",
    "lng": "-51.22803440001900000"
},
"2": {
    "lat": "-30.02846288697400000",
    "lng": "-51.22814140001900000"
},
"3": {
    "lat": "-30.02822088697400000",
    "lng": "-51.22821640001900000"
},
"4": {
    "lat": "-30.02760388697400000",
    "lng": "-51.22844040001900000"

如何将其映射到数组以在Angular应用中使用？到目前为止，我已经尝试过创建一个没有运气的对象数组：

export class MyClass {
  lat: string;
  lng: string;
}

和...

handleSuccessfulResponse(response) {
  this.myClass = response;
}

我在做什么错了？

Answer 1

您可以按以下方式使用方法Objects.values()：

const result = {
  "0": {
    "lat": "-30.02897288697400000",
    "lng": "-51.22800440001900000"
  },
  "1": {
    "lat": "-30.02879088697400000",
    "lng": "-51.22803440001900000"
  },
  "2": {
    "lat": "-30.02846288697400000",
    "lng": "-51.22814140001900000"
  },
  "3": {
    "lat": "-30.02822088697400000",
    "lng": "-51.22821640001900000"
  },
  "4": {
    "lat": "-30.02760388697400000",
    "lng": "-51.22844040001900000"
  }
};

const myArray = Object.values(result);
console.log(myArray);

Answer 2

您可以为此使用Object.values，查找代码段以获取更多详细信息。

let obj={
"0": {
    "lat": "-30.02897288697400000",
    "lng": "-51.22800440001900000"
},
"1": {
    "lat": "-30.02879088697400000",
    "lng": "-51.22803440001900000"
},
"2": {
    "lat": "-30.02846288697400000",
    "lng": "-51.22814140001900000"
},
"3": {
    "lat": "-30.02822088697400000",
    "lng": "-51.22821640001900000"
}}

let arr=Object.values(obj);
console.log(arr)
