我正在尝试使用谷歌地图v3 api创建一个地图。我在互联网上找到了下面的代码，我想在地图窗口中显示纬度和经度，而不是地址。
<script>
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-33.8688, 151.2195),
zoom: 13,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map_canvas'),
mapOptions);
var input = document.getElementById('searchTextField');
var autocomplete = new google.maps.places.Autocomplete(input);
autocomplete.bindTo('bounds', map);
var infowindow = new google.maps.InfoWindow();
var marker = new google.maps.Marker({
map: map
});
google.maps.event.addListener(autocomplete, 'place_changed', function() {
infowindow.close();
marker.setVisible(false);
input.className = '';
var place = autocomplete.getPlace();
if (!place.geometry) {
// Inform the user that the place was not found and return.
input.className = 'notfound';
return;
}
// If the place has a geometry, then present it on a map.
if (place.geometry.viewport) {
map.fitBounds(place.geometry.viewport);
} else {
map.setCenter(place.geometry.location);
map.setZoom(17); // Why 17? Because it looks good.
}
var image = {
url: place.icon,
size: new google.maps.Size(71, 71),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(17, 34),
scaledSize: new google.maps.Size(35, 35)
};
marker.setIcon(image);
marker.setPosition(place.geometry.location);
marker.setVisible(true);
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(' ');
}
infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + address);
infowindow.open(map, marker);
});
请有人帮我获取并显示经纬度。非常感谢。
你在哪里有
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(' ');
}
infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + address);
infowindow.open(map, marker);
将infowindow行更改为
infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + place.geometry.location.lat() + ',' + place.geometry.location.lng());
更简单的解决方案是：
var address = "New Delhi"
$.ajax({
url:"http://maps.googleapis.com/maps/api/geocode/json?address="+address+"&sensor=false",
type: "POST",
success:function(res){
console.log(res.results[0].geometry.location.lat);
console.log(res.results[0].geometry.location.lng);
}
});
干杯！
看看这段代码。。
<!DOCTYPE html>
<html>
<head>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
<script>
function initialize() {
var address = 'Kolkata';
geocoder = new google.maps.Geocoder();
geocoder.geocode({
'address': address
}, function(results, status) {
var lat=document.getElementById("lat").innerHTML=results[0].geometry.location.lat();
var lng=document.getElementById("lng").innerHTML=results[0].geometry.location.lng();
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<p id="lat"></p>
<p id="lng"></p>
</body>
