Ich versuche, meinen Markern auf einer Google-Karte etwas InfoWindow-Inhalt hinzuzufügen. Ich kann meinen Server abfragen, Daten abrufen und die Markierungen auf die Karte setzen. Das funktioniert. Was nicht funktioniert ist, dass nichts passiert, wenn ich auf den Marker klicke. Ich würde denken, dass das Infowindow erscheinen würde. Leider ist es so lange her, dass ich Google Maps programmiert habe. Aus irgendeinem Grund wird das Klickereignis der Markierung nicht aufgerufen. Irgendwelche Vorschläge bezüglich meiner Dummheit werden geschätzt.Infofenster zu Google Maps hinzufügen
TIA<script>
var map, geocoder;
var Markers = [];
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
center: { lat: 0.0, lng: 0.0 },
zoom: 12
});
if (!Modernizr.geolocation) {
alert("Your browser sucks. Get a new one, maybe one that is up to date and supports GPS.")
return;
}
else {
navigator.geolocation.getCurrentPosition(show_map);
}
}
function show_map(position) {
map.setZoom(12);
var Latitude = position.coords.latitude;
var Longitude = position.coords.longitude;
map.setCenter({ lat: Latitude, lng: Longitude });
var bounds = map.getBounds();
var url = "/api/xxxxxxxxjsonendpoint";
var lowerLeft = bounds.getSouthWest();
var upperRight = bounds.getNorthEast();
var lat0 = lowerLeft.lat();

Hier ist die jüngste Aktualisierung von meinem Code. Immer noch keine worky ........

alert("Your browser sucks. Get a new one, maybe one that is up to date and supports GPS.")
return;
}
else {
navigator.geolocation.getCurrentPosition(show_map);

'position: geocodeAddress (Geocoder, Karte, Adresse)' die 'geocodeAddress' Funktion nicht (und kann nicht, weil es asynchron ist) alles zurückgeben. – geocodezip
