Cha*_*dra 39 javascript google-maps geocoding latitude-longitude
我的页面中有一个文本框,其中包含位置名称和带文本的按钮getLat&Long.现在单击我的按钮,我必须在文本框中显示警报latitude和longitude位置.有什么建议吗？

您可以使用Google Maps API中的Google地理编码器服务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
}
});

你是否包含v3 javascript API？
<script type="text/javascript"
src="http://maps.google.com/maps/api/js?sensor=set_to_true_or_false">
</script>

我希望这可以帮助将来的某个人.
你可以使用谷歌地理编码API,如前所述,我最近必须做一些工作,我希望这有助于:
<!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,您可以在代码中看到它,它从输入中获取地址,并在键入时由API自动完成.
点击按钮后,您的地址就会根据需要通过警报获得结果.另请注意,这使用最新的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.

OUTPUT = json或xml;

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.
我希望这对于未来范围包含具有纬度和经度的自动完整Google API功能更有用
var latitude = place.geometry.location.lat();
var longitude = place.geometry.location.lng();
