自動完成地址輸入

Question

我正在使用Google自動完成地址搜索腳本。

因此，當用戶輸入地址時，輸入自動隨搜索結果一起顯示。目前這顯示整個詞的地址，但我只需要英國地址

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); 
     } 

     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; 
      } 
     } 
     } 

     // 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()); 
      }); 
     } 
     } 



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

有沒有辦法將此限制在英國？

嘗試改變這種功能，唯一的變化是在你傳遞給自動完成選項通過添加組件限制

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'], 
     componentRestrictions: { country: "uk" } 
    }); 

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