detect the zoom with the jquery-ui-map

Question

I use the Google maps v3 plugin for jQuery. All I want to do is to detect the zoom. With the code below

 var map = $('#map_canvas').gmap('get', 'map');
$(map).addEventListener('zoom_changed', function() {
    alert(map);
});

I can detect if the zoom has changed but I don't know the exact zoom. So, how can I detect the zoom?

Answer 1

There is probable an event variable passed in there.

Try using it:

var map = $('#map_canvas').gmap('get', 'map');
$(map).addEventListener('zoom_changed', function(event) {
    alert(map);
    //... use event
});
