我正试图将某些值从JSON对象添加到新的JSON对象。因为我正在使用的当前地址解析器似乎没有提供有效的geoJSON以供在地图加载功能中使用。那么我可以在新对象中添加允许的值，以便对其进行查询吗？
我有geoCoder的返回结果，我使用剥离了这些值
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]}"

在创建permittedValues时不要使用字符串连接，只需提取所需的属性即可。
var permittedValues = business1.map(({type, geometry}) => ({type, geometry}));
var newObj = {

答案 1 :(得分：0)
假设返回的结果是“结果”，您是否尝试访问geometry[0]？您正在尝试做的事情似乎很费劲。是否没有getter或API /响应中的方法可以访问此数据？
