Question

我正在尝试使用HTML 5 GeoLocation获取经度和纬度，然后使用Google Maps API 获取该经度/纬度的国家/地区代码。有没有更简单的方法从google places api获取国家/地区代码？

我发现此链接的解决方案==＆gt; Getting country code from Google Maps and HTML 5 GeoLocation 获取国家代码。

有没有办法直接从google places api获取国家/地区代码，而不先获取经度和经度，然后传递到google maps api。

这是我用来从google places api

获取国家/地区代码的以下脚本

<script>
// This example displays an address form, using the autocomplete feature
// of the Google Places API to help users fill in the information.

var placeSearch, autocomplete;
var componentForm = {
street_number: 'short_name',
route: 'long_name',
locality: 'long_name',
administrative_area_level_1: 'short_name',
country: 'long_name',
postal_code: 'short_name'
};

function initAutocomplete() {
  // Create the autocomplete object, restricting the search to geographical
 // location types.
  autocomplete = new google.maps.places.Autocomplete(
  /** @type {!HTMLInputElement}     */(document.getElementById('autocomplete')),
  {types: ['(cities)']});

  // When the user selects an address from the dropdown, populate the address
  // fields in the form.
  //autocomplete.addListener('place_changed', fillInAddress);

// Get Latitude and longitude

  google.maps.event.addListener(autocomplete, 'place_changed', function () {
        var place = autocomplete.getPlace();
        //document.getElementById('city2').value = place.name;
        document.getElementById('lat').value = place.geometry.location.lat();
        document.getElementById('lng').value = place.geometry.location.lng();

    });
}

// [START region_fillform]
function fillInAddress() {
 // Get the place details from the autocomplete object.
 var place = autocomplete.getPlace();

  for (var component in componentForm) {
   document.getElementById(component).value = '';
   document.getElementById(component).disabled = false;
  }

  // Get each component of the address from the place details
 // and fill the corresponding field on the form.
 for (var i = 0; i < place.address_components.length; i++) {
   var addressType = place.address_components[i].types[0];
   if (componentForm[addressType]) {
    var val = place.address_components[i][componentForm[addressType]];
    document.getElementById(addressType).value = val;
  }
  }
  }
  // [END region_fillform]

Answer 1

要获取国家/地区代码，请获取类型为country的地址组件的简称：

// for the country, get the country code (the "short name") also
if (addressType == "country") {
  document.getElementById("country_code").value = place.address_components[i].short_name;
}

function fillInAddress() {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();

  for (var component in componentForm) {

  // Get each component of the address from the place details

使用以下功能，您将获得邮政编码，国家，州，城市等。

export let placeAddresCompoponent = {
    ZIP_CODE: 'postal_code',
    COUNTRY: 'country',
    STATE: 'administrative_area_level_1',
    CITY: 'administrative_area_level_2',
    TOWN: 'sublocality_level_1',
    AREA: 'sublocality_level_2',
    NEAREST_ROAD: 'route'
}

使用以下功能从地址组件获取数据。您将从 Google Place Api 的结果中获得 address_components 。

export function getAddressComponent(address_components, key) {
    var value='';
    var postalCodeType = address_components.filter(aComp =>
        aComp.types.some(typesItem => typesItem === key))
    if (postalCodeType != null && postalCodeType.length > 0)
        value = postalCodeType[0].long_name
    return value;
}

您可以使用下面的地址获取特定地址。

addressComponent =来自Google Place API结果的 address_components 数组

var zipCode = getAddressComponent(addressComponent, placeAddresCompoponent.ZIP_CODE)
var country = getAddressComponent(addressComponent, placeAddresCompoponent.COUNTRY)
console.log('zipCode : ', zipCode)
console.log('country : ', country)

  postal_code: 'short_name',
  political: 'short_name'
};

function initAutocomplete() {
  // Create the autocomplete object, restricting the search to geographical
  // location types.
  autocomplete = new google.maps.places.Autocomplete(
      /** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
      {types: ['(cities)']});

  // When the user selects an address from the dropdown, populate the address
  // fields in the form.
  autocomplete.addListener('place_changed', fillInAddress);
}

// [START region_fillform]
function fillInAddress() {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();

  for (var component in componentForm) {
    document.getElementById(component).value = '';
    document.getElementById(component).disabled = false;
  }

  // Get each component of the address from the place details
  // and fill the corresponding field on the form.
  for (var i = 0; i < place.address_components.length; i++) {
    var addressType = place.address_components[i].types[0];
    if (componentForm[addressType]) {
      var val = place.address_components[i][componentForm[addressType]];
        if(place.address_components[i][componentForm['political']]){
            console.log(place.address_components[i][componentForm['country']]);
            if(isNaN(place.address_components[i][componentForm['political']])){
                country_code=place.address_components[i][componentForm['political']];
                var country_name=place.address_components[i][componentForm['country']];
            }
        }
      document.getElementById(addressType).value = val;

    }
  }
  // **Country code, Country name goes here**
  document.getElementById("Country_code").value=country_code;
