how to handle the event when markers load into memory .

Question

i have many makers (maybe 500) to insert to maps, so i want to Optimization them

google.maps.event.addListener(marker, 'visible_changed', function() {
                alert('ww')
            });

this code can't alert 'ww', when i zoom in the map(so some marker will not be seen)

why can't trigger the 'visible_changed' event when zoomin

and how to handle the event when the marker is loaded into memory,

If you would like to display this many markers you should be using marker clusterer or marker manager - they will do all the hard work for you - all you need to do is pass an array of marker objects to them. More info here http://code.google.com/p/google-maps-utility-library-v3/wiki/Libraries and a demo here

• Marker Manager http://google-maps-utility-library-v3.googlecode.com/svn/tags/markermanager/1.0/docs/examples.html
• Marker Clusterer - http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerclusterer/1.0/examples/advanced_example.html

Hello, I have similar problem. I want to catch event, when marker is displayed on a page. I´m working on my diploma paper and I need to test different browsers and show up script duration. Any idea?
