Question

我在我的网站上使用以下代码自动填充地址并显示各个字段。

工作正常，但是当用户输入时，它会从世界各地提取地址，直到他们进一步进入地址。

我想暂时将国家锁定到美国并尝试了几个小提琴，但无法让代码发挥得很好。

希望得到一些帮助 - 谢谢

<script src="https://maps.googleapis.com/maps/api/js?key=123xyz&signed_in=true&libraries=places&callback=initAutocomplete"
        async defer></script>

<script>    
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: ['geocode']});

  // 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]];
      document.getElementById(addressType).value = val;
    }
  }
}
// [END region_fillform]

// [START region_geolocation]
// Bias the autocomplete object to the user's geographical location,
// as supplied by the browser's 'navigator.geolocation' object.
function geolocate() {
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
      var geolocation = {
        lat: position.coords.latitude,
        lng: position.coords.longitude
      };
      var circle = new google.maps.Circle({
        center: geolocation,
        radius: position.coords.accuracy
      });
      autocomplete.setBounds(circle.getBounds());
    });
  }
}
// [END region_geolocation]

</script>

我猜这与以下内容有关，但无论我在那里尝试它都没有什么不同。

  autocomplete = new google.maps.places.Autocomplete(
      /** @type {!HTMLInputElement}   */(document.getElementById('autocomplete')),
      {types: ['geocode']});

您是否尝试过以下操作？你提到你已经尝试了几件事，但没有透露更多：

function initAutocomplete() {
    var options = {
        types: ['(geocode)'],
        componentRestrictions: {country: "us"}
    };

    var input = document.getElementById('autocomplete');
    autocomplete = new google.maps.places.Autocomplete(input, options);
}

如果这不起作用，那么设置一个小提琴并显示给我们，这样我们就可以尝试让它为你工作。
