触发任何Google Map事件后如何触发动作

Question

I am implementing an app using Google Maps API 3. I would like to know what is the best implementation in dealing with this problem. I want to execute an action once ANY event in Google Map has been fired. Currently, what I am doing is that I call the function every time a specific event is called. I find this redundant and I have to make a listener for all of the events. So, is there a way to generalize this where I can do the following:

google.maps.addListener(everything_on_the_map_canvas, 'ANY_EVENT', function(event) {
  foo();
})

function foo(){
 //do something here
}

Thank you.

If the user decides to continue with map operations, they will have to move the mouse over the map to do anything. So you could simply trap a mousemove .

google.maps.event.addListener(map, 'mousemove', function(event) {foo();})

If the user can manipulate the map without moving the mouse over the map, then you will need to listen to other events.

• bounds_changed will cover most eventualities with zoom and pan, heading and the like
• maptype_id_changed

But that's only three instead of all of them. If the bounds don't change when the tilt does (and you can change tilt from outside the map) you may need to listen for tilt_changed as well.
