javascript - 将某些值从一个 JSON 对象添加到另一个对象

转载作者：行者123 更新时间：2023-11-29 23:05:17

我试图笨拙地将某些值从 JSON 对象添加到新的 JSON 对象。因为我正在使用的当前地理编码器似乎没有提供有效的 geoJSON 以供在 map 加载功能中使用。那么我可以向新对象添加允许的值以便可以查询吗？

我有一个 geoCoder 的返回结果，我使用它去除了值

var businessLoc = JSON.stringify(business1);

permittedValues = [].concat(
  ...business1.map(v => [
    "type:" + v.type + ",",
    "geometry{" + v.geometry + "}"
  ])
);

console.log(permittedValues);

var newObj = {
  type: "FeatureCollection",
  features: [{

  }]
};

var jsonObj = {};

features = newObj.features.geometry;

for (i = 0; i < permittedValues.length; i++) {
  newObj.features[i] = permittedValues[i];
}

console.log(newObj);

map.addSource("sample", {
  type: "geojson",
  data: newObj
});

结果

0: "type:Feature,"
1: "geometry{[object Object]}"
2: "type:Feature,"
3: "geometry{[object Object]}"
4: "type:Feature,"
5: "geometry{[object Object]}"
6: "type:Feature,"
7: "geometry{[object Object]}"
8: "type:Feature,"
9: "geometry{[object Object]}"
10: "type:Feature,"
11: "geometry{[object Object]}"
12: "type:Feature,"
13: "geometry{[object Object]}"

我想要什么

  {
    "type": "FeatureCollection",
    "features": [
      {
        "type": "Feature",
        "geometry": {
          "type": "Point",
          "coordinates": [

什么接近工作

permittedValues = [].concat(...business1.map((v) => [v.geometry]))



var newObj = {
  type: "FeatureCollection",
  features:[{
    type:'Feature',
    geometry:permittedValues[0]
  }]
};

最佳答案

在创建 permittedValues 时不要使用字符串连接，只需提取您想要的属性即可。

var permittedValues = business1.map(({type, geometry}) => ({type, geometry}));
var newObj = {
  type: "FeatureCollection",
  features: permittedValues
};

var business1 = [
