问题描述
我正在尝试使用Google Maps v3 api创建地图。我在互联网上发现了下面的代码,我想在地图窗口中显示纬度和纬度,而不是地址。
<脚本>
函数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){
//通知用户该地点未找到并返回。
input.className ='notfound';
return;
}
//如果该地点有一个几何图形,则将其显示在地图上。 $ b if(place.geometry.viewport){
map.fitBounds(place.geometry.viewport);
} else {
map.setCenter(place.geometry.location);
map.setZoom(17); //为什么是17?因为它看起来不错。
}
var image = {
url:place.icon,
size:new google .maps.Size(71,71),
原点:新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);
});
//设置单选按钮上的侦听器来更改Places
// Autocomplete中的过滤器类型。
函数setupClickListener(id,types){
var radioButton = document.getElementById(id);
google.maps.event.addDomListener(radioButton,'click',function(){
autocomplete.setTypes(types);
});
}
setupClickListener('changetype-all',[]);
setupClickListener('changetype-establishment',['establishment']);
setupClickListener('changetype-geocode',['geocode']);
}
google.maps.event.addDomListener(window,'load',initialize);

请有人帮我获取并显示经纬度。

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
<$ p ()+ place.name +'< / strong>< br>' ','+ place.geometry.location.lng());
I am trying create a map using google maps v3 api. I have found the below code over internet and I want to show the latitude and logitude in map window instead of address.
<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);
});
// Sets a listener on a radio button to change the filter type on Places
// Autocomplete.
function setupClickListener(id, types) {
var radioButton = document.getElementById(id);
google.maps.event.addDomListener(radioButton, 'click', function() {
autocomplete.setTypes(types);
});
}
setupClickListener('changetype-all', []);
setupClickListener('changetype-establishment', ['establishment']);
setupClickListener('changetype-geocode', ['geocode']);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div>
<input id="searchTextField" type="text" size="50">
<input type="radio" name="type" id="changetype-all" checked="checked">
<label for="changetype-all">All</label>
<input type="radio" name="type" id="changetype-establishment">
<label for="changetype-establishment">Establishments</label>
<input type="radio" name="type" id="changetype-geocode">
<label for="changetype-geocode">Geocodes</lable>
</div>
<div id="map_canvas"></div>
</body>
</html>
Please some one help me to get and show latitude and longitude.Thanks,Enamul
解决方案
Where you have
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);
Change the infowindow line to read
infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + place.geometry.location.lat() + ',' + place.geometry.location.lng());
