Javascript event handling for Google Maps

I am using google maps + javascript + php in my application. I want to know two things:
In google maps,

  1. does moveend event ALWAYS gets fired AFTER zoomend/dragend (whichever of two) event occurs.

  2. When I click zoom icon on google map or scroll the mouse wheel to zoom, the zoomend event gets fired more than once. If I zoom in one step using + icon on map, the zoomend event gets fired twice or sometimes more. any possible loophole.

    And so want to know how to stop further event propogation in javascript. (remember I need not use clearListeners as it will forever ignore event handler which is undesirable).

Thank you.

I set up listeners for 'moveend', 'zoomend', and 'dragend' to try it out.

GEvent.addListener(map, "moveend", function() { console.log('moveend'); });
GEvent.addListener(map, "zoomend", function() { console.log('zoomend'); });
GEvent.addListener(map, "dragend", function() { console.log('dragend'); });

It appears that 'moveend' always fires after 'zoomend' or 'dragend'.

However, no events ever fired more than once at a time. Maybe you accidentally set up two simultaneous listeners. You shouldn't need to use stopPropagation or cancelBubble.

you could try just reuturning false or null from the event. If that doesn't work trying using "event.cancelBubble = true" or "event.stopPropagation"
