ねえ、私はGoogleマップAPIを初めて使用します。マップが埋め込まれています。地理位置情報を使用してユーザーの緯度と経度を取得し、マップAPIのギャップを埋めています。ただし、生成された緯度と経度を使用するとマップは機能しませんが、入力するだけで機能します
動かないコード:
var map;
var infowindow;
function initialize() {
if (navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(showPosition);
}
function showPosition(position)
{
var latlon = new google.maps.LatLng( position.coords.latitude + "," + position.coords.longitude );
map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: latlon,
zoom: 15,
disableDefaultUI: true
});
var request = {
location: latlon,
radius: 555,
types: ['bar']
};
infowindow = new google.maps.InfoWindow();
var service = new google.maps.places.PlacesService(map);
service.search(request, callback);
}
function callback(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
for (var i = 0; i < results.length; i++) {
createMarker(results[i]);
}
}
}
}
function createMarker(place) {
var placeLoc = place.geometry.location;
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location
});
google.maps.event.addListener(marker, 'click', function() {
alert(place.name);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
作業コード
var map;
var infowindow;
function initialize() {
var latlon = new google.maps.LatLng(-33.8665433, 151.1956316);
map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: latlon,
zoom: 15,
disableDefaultUI: true
});
var request = {
location: latlon,
radius: 555,
types: ['bar']
};
infowindow = new google.maps.InfoWindow();
var service = new google.maps.places.PlacesService(map);
service.search(request, callback);
}
function callback(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
for (var i = 0; i < results.length; i++) {
createMarker(results[i]);
}
}
}
function createMarker(place) {
var placeLoc = place.geometry.location;
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location
});
google.maps.event.addListener(marker, 'click', function() {
alert(place.name);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
いただければ幸いです:)
