Google Maps API：获取机场名称

Question

当我搜索机场时，我得到如下结果：

点击第一个结果“拉瓜迪亚机场 (LGA)”，但给了我这个地方结果：

{
  "address_components": [
    {
      "long_name": "New York",
      "short_name": "New York",
      "types": [
        "locality",
        "political"
      ]
    },
    {
      "long_name": "East Elmhurst",
      "short_name": "East Elmhurst",
      "types": [
        "neighborhood",
        "political"
      ]
    },
    {
      "long_name": "Queens",
      "short_name": "Queens",
      "types": [
        "sublocality_level_1",
        "sublocality",
        "political"
      ]
    },
    {
      "long_name": "Queens County",
      "short_name": "Queens County",
      "types": [
        "administrative_area_level_2",
        "political"
      ]
    },
    {
      "long_name": "New York",
      "short_name": "NY",
      "types": [
        "administrative_area_level_1",
        "political"
      ]
    },
    {
      "long_name": "United States",
      "short_name": "US",
      "types": [
        "country",
        "political"
      ]
    },
    {
      "long_name": "11371",
      "short_name": "11371",
      "types": [
        "postal_code"
      ]
    }
  ],
  "formatted_address": "New York, Queens, NY 11371, USA",
  "vicinity": "New York",
  "html_attributions": []
}

“LaGuardia Airport”或“LGA”在结果中的任何位置。

如何获得地点的名称？

---

这是我的代码的要点：

const autocomplete = new gmaps.places.Autocomplete(addressInput, {}); // {types: ['address']}
autocomplete.setFields(['address_component','formatted_address','vicinity']);

autocomplete.addListener('place_changed', () => {
    let place = autocomplete.getPlace();

    if (place.address_components && place.address_components.length) {
        console.log(JSON.stringify(place, null, 2))
    }
}

Answer 1

地点的“名称”（在您的情况下为“拉瓜迪亚机场”）位于地点对象的名称属性中。

来自the documentation：

名称 可选
类型：字符串可选
地点的名称。

如果您查看文档中的 Google 自动完成示例： https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete

infowindowContent.children["place-name"].textContent = place.name;

您将在信息窗口中看到单击该条目时创建的标记。
