When we click on this marker, a detailed information window will show, just like this : I search the "white house",then it create a marker "A". This is not difficult. However I found something more interesting: In the map view, even we do not search anything, when the map zoom to some specified level, there will be some anchors generated. If the mouse over it or click it, it will show something

问题 I need to have a map with a list of markers on it. It needs to transition between these smoothly. I have the following code which currently loops around the markers. var x = 0; function pan_to() { if(x >= addresses.length){ x=0; } $.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address='+addresses[x]+'&sensor=false', null, function (data) { var p = data.results[0].geometry.location var latlng = new google.maps.LatLng(p.lat, p.lng); map.panTo(latlng); }); x++; } setInterval(pan_to
