问题 I seek to change the position of markers in google maps with the value of the real-time database I try to mMap.clear to but it's not the right solution because if I have 100 markers and change position of 1 marker the 100 is clear and reposition for make 1 marker change myRef.addValueEventListener(new ValueEventListener() { @Override public void onDataChange(DataSnapshot dataSnapshot) { mMap.clear(); for (DataSnapshot ds : dataSnapshot.getChildren()) { Double lang = ds.child("lang").getValue

问题 I have a Google Map (v3) that I am placing several markers into, and want to be able to click on the markers and pull up a Fancybox iFrame. I can't figure out how to pull the URL from the marker into Fancybox. I can see the Fancybox firing - the popup window appears breifly and then the link is pulled up as a new page over top of the current page. Here is a snippet of the relevant code: var sites = [ ['Mount Evans', 39.58108, -105.63535, 4, 'www.myurl-1.com'], ['Irving Homestead', 40.315939,

问题 I'm very new to React and web development, so hopefully this makes sense. So I'm building an App that uses Google Maps api and React to show markers of places that I fetch from Foursquare. I generate an array of places from Foursquare (Limited to 5 places that I want to keep static) and placed it in the state of my app so I can pass the data to both a List sidebar and my Map to generate markers. I have also created a Filter search bar that I want to use to filter the List AND the Map Markers

问题 marker = new google.maps.Marker({ icon: image, position: new google.maps.LatLng(locations[i][1], locations[i][2]), flat: true, optimized: false, map: map, visible: true, customInfo: locations[i][0] }); I have the above to build my Marker in my Google Map but when the marker is clicked, the map zooms to the location and I'd like to make the marker non clickable. I have tried the following with no success google.maps.event.addListener(marker, 'click', function() { map.setZoom(17); map.setCenter

问题 I know the topic has already been discussed many times, but I can't resolve my problem. I'd like to display some markers on my map, with a click event on each of them. Each click event should open an infoWindow with some data. Here is what I wrote ; this code runs without any error in the console, all the markers are correctly displayed, but the infowindow displayed on click is always the same for all... //Global variable var info = new google.maps.InfoWindow(); //... some other functions

问题 When going to the Google website and signin in you can click on the “Maps” option from the toolbar menu at the top of the page.
