How do I delete a marker on Google Maps?

阅读更多关于 How do I delete a marker on Google Maps?

问题 I only know of one way: Right click and click 'delete me' How else can I delete markers on Google Maps? This is my code now: GEvent.addListener(marker, 'mousedown', function(e) { alert(e) if (e.button == 2){ alert('sss') map.removeOverlay(marker); } When i right-click, it alerts (40.23141543543321,114.3214121421) ; when I look at the API, I see this: mousedown(latlng:GLatLng) so I think that e is not an event, but a 'GLatLng' If I use the 'singlerightclick', nothing happens when i right-click

Google Maps: Border on Markers

阅读更多关于 Google Maps: Border on Markers

问题 I'm trying to display photos as markers on Google Maps. This is no problem by redefining the marker as an image, but I want to put some sort of border or shadow to make them stand out better. Something like the Google photos would be best, but I guess this is too complicated, if at all possible. A simple 1px solid border would do fine. One option is to actually change the image, but this is not an option. Also, the images are different sizes so I can not put a black image as the shadow (1px

I'm trying to create markers on Google Maps v2 from my mySQL database and it is not working. The map does come up but there are no markers.
