Google Maps API 3 - Check if marker is in view

I see 开发者_如何学Gothat there is a getVisible call, but that only checks if the marker is on the map NOT if the marker is in the current view.

I want to check if the marker is in the current view bounds?

I guess you want

map.getBounds().contains(marker.getPosition())

You need to tell map that your markers should be contained within view by adding following code

google.maps.event.addListener(map, 'bounds_changed', function() {
    map.getBounds().contains(marker.getPosition()) 
});

Here bound_changed event is triggered.
