detecting visible google map markers after setZoom
I'm using google map fitBounds, then I use map.setZoom to zoom-in one level (after google finds the best zoom level to fit my markers), then I want to check weather my markers are visible in viewport or not, how can I do so? it seems that map.getBounds().contains doesn't work, please take a look at this fiddle: fiddle
I want to check my marker is visible or not:
google.maps.event.addListenerOnce(map, "zoom_changed", function() {
map.setZoom(map.getZoom()+2);
if( map.getBounds().contains("35.700592","51.394773"))
alert('ok');
but there seems to be an error
//alert("the zoom level is now "+map.getZoom());
});
Why do you think "35.700592","51.394773" is a google.maps.LatLng? It is two strings separated by a comma.
This won't work:
google.maps.event.addListenerOnce(map, "zoom_changed", function() {
map.setZoom(map.getZoom()+2);
if( map.getBounds().contains("35.700592","51.394773"))
alert('ok');
});
This is the correct way to use "contains" (with a LatLng object):
google.maps.event.addListenerOnce(map, "zoom_changed", function() {
map.setZoom(map.getZoom()+2);
if( map.getBounds().contains(new google.maps.LatLng(35.700592,51.394773)))
alert('ok');
});
And you probably want to make an array containing your markers and use .getPosition() on the markers
