Question

我的页面中有一个文本框，其中包含位置名称和带有文本getLat&Long的按钮。现在点击我的按钮，我必须在文本框中显示latitude和longitude位置的提醒。有什么建议吗？

Answer 1

您可以使用Google Geocoder service中的Google Maps API将您的位置名称转换为纬度和经度。所以你需要一些代码：

var geocoder = new google.maps.Geocoder();
var address = document.getElementById("address").value;
geocoder.geocode( { 'address': address}, function(results, status) {
  if (status == google.maps.GeocoderStatus.OK)
  {
      // do something with the geocoded result
      //
      // results[0].geometry.location.latitude
      // results[0].geometry.location.longitude
  }
});

您是否包含v3 javascript API？

<script type="text/javascript"
     src="http://maps.google.com/maps/api/js?sensor=set_to_true_or_false">
</script>

Answer 2

我希望这可以在将来帮助某人。

你可以使用Google Geocoding API，如前所述，我最近必须做一些工作，我希望这会有所帮助：

<!DOCTYPE html>
<html>
    <head>
        <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
        <script type="text/javascript">
        function initialize() {
        var address = (document.getElementById('my-address'));
        var autocomplete = new google.maps.places.Autocomplete(address);
        autocomplete.setTypes(['geocode']);
        google.maps.event.addListener(autocomplete, 'place_changed', function() {
            var place = autocomplete.getPlace();
            if (!place.geometry) {
                return;
            }

        var address = '';
        if (place.address_components) {
            address = [
                (place.address_components[0] && place.address_components[0].short_name || ''),
                (place.address_components[1] && place.address_components[1].short_name || ''),
                (place.address_components[2] && place.address_components[2].short_name || '')
                ].join(' ');
        }
      });
}
function codeAddress() {
    geocoder = new google.maps.Geocoder();
    var address = document.getElementById("my-address").value;
    geocoder.geocode( { 'address': address}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {

      alert("Latitude: "+results[0].geometry.location.lat());
      alert("Longitude: "+results[0].geometry.location.lng());
      } 

      else {
        alert("Geocode was not successful for the following reason: " + status);
      }
    });
  }
google.maps.event.addDomListener(window, 'load', initialize);

        </script>
    </head>
    <body>
        <input type="text" id="my-address">
        <button id="getCords" onClick="codeAddress();">getLat&Long</button>
    </body>
</html>

现在这也有一个autocomlpete函数，你可以在代码中看到它，它从输入中获取地址，并在输入时由API自动完成。

点击按钮后，您可以根据需要通过提醒获得结果。另请注意，这会使用最新的API并加载'places'库（调用API时使用'libraries'参数）。

希望这会有所帮助，并阅读文档以获取更多信息，欢呼。

http://maps.googleapis.com/maps/api/geocode/OUTPUT?address=YOUR_LOCATION&sensor=true

OUTPUT = json或xml;

有关google map api的详细信息，请访问url：

http://code.google.com/apis/maps/documentation/geocoding/index.html

希望这会有所帮助

Answer 4

以下是我使用的代码。它工作得很好。

var geo = new google.maps.Geocoder;
geo.geocode({'address':address},function(results, status){
    if (status == google.maps.GeocoderStatus.OK) {              
        var myLatLng = results[0].geometry.location;

        // Add some code to work with myLatLng              

    } else {
        alert("Geocode was not successful for the following reason: " + status);
    }
});

希望这会有所帮助。

Answer 5

我希望这对将来范围包含自动完成的Google API功能更有用纬度和经度

var latitude = place.geometry.location.lat();
var longitude = place.geometry.location.lng();

Answer 6

我建议使用以下代码，您可以使用此<script language="JavaScript" src="http://j.maxmind.com/app/geoip.js"></script>来获取某个位置的纬度和经度，虽然它可能不那么准确，但它对我有效;

下面的代码段

<!DOCTYPE html>
<html>
<head>
<title>Using Javascript's Geolocation API</title>

<script type="text/javascript" src="http://j.maxmind.com/app/geoip.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>
<body>
<div id="mapContainer"></div> 

<script type="text/javascript">

        var lat = geoip_latitude();
        var long = geoip_longitude();
        document.write("Latitude: "+lat+"</br>Longitude: "+long);

</script> 
</body>
</html>

Answer 7

通过自动填充输入位置，并在所有字段的其余部分输入：自动填充纬度和经度值。
将API KEY替换为您的Google API密钥

    var autocomplete = new google.maps.places.Autocomplete(input, options);

    google.maps.event.addListener(autocomplete, 'place_changed', function() {
