Question

我对此非常陌生，想知道如何获取完整的字符串而不是当前正在进行的第一个字符，

目前正在使用https://developers.google.com/maps/documentation/javascript/examples/geocoding-reverse

中的html + js示例

function codeLatLng(callback) {
  var input = document.getElementById('latlng').value;
  var latlngStr = input.split(',', 2);
  var lat = parseFloat(latlngStr[0]);
  var lng = parseFloat(latlngStr[1]);
  var latlng = new google.maps.LatLng(lat, lng);



    geocoder.geocode({'latLng': latlng}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {

      if (results[1]) {
        map.setZoom(17);
        marker = new google.maps.Marker({
            position: latlng,
            map: map



        });
       infowindow.setContent(results[0].formatted_address);
        infowindow.open(map, marker);
    document.getElementById('Addressb').value= results[0].formatted_address; //working
    document.getElementById('Strn').value = results[0].formatted_address[0];
    document.getElementById('Strna').value = results[0].formatted_address[2];




      } else {
        alert('No results found');
     }
   } else {
      alert('Geocoder failed due to: ' + status);
    }
  });

}



google.maps.event.addDomListener(window, 'load', initialize);



    </script>

结果需要存储在指定的文本字段中，如下所示

Street Number: <input id="Strn" type="text"><br>
    Street Name: <input id="Strna" type="text"><br>
    Suburb: <input id="Subu" type="text"><br>
    Town: <input id="Town" type="text"><br>
    Code: <input id="Code1" type="text"><br>

Answer 1

你必须遍历地址组件，然后是类型，这里是代码

  var streetNumber;
  var streetName;
  var city;
  var state;
  var zip;
  var country;
  for(var i = 0; i < results[0].address_components.length; i++){
    for(var k = 0; k < results[0].address_components[i].types.length; k++){
        if (results[0].address_components[i].types[k] == "street_number")
            streetNumber = results[0].address_components[i].long_name;
        else if (results[0].address_components[i].types[k] == "route")
            streetName = results[0].address_components[i].short_name;
        else if (results[0].address_components[i].types[k] == "locality")
            city = results[0].address_components[i].long_name;
        else if (results[0].address_components[i].types[k] == "administrative_area_level_1")
            state = results[0].address_components[i].long_name;
        else if (results[0].address_components[i].types[k] == "postal_code")
            zip = results[0].address_components[i].long_name;
        else if (results[0].address_components[i].types[k] == "country")
            country = results[0].address_components[i].long_name;
    }
  }

Answer 2

Here's a link Google地图地理编码文档，指定响应的格式。

它看起来确实按照特定的顺序在address_components数组中单独返回地址的组件。因此，如果您要对街道地址进行地理编码，则address_components[0].long_name应返回街道地址，address_components[1].long_name街道名称等。

希望有所帮助。
