I'm trying to find a way to add some UI feedback to scroll wheel zoom
in firefox. In chrome, the map zooms visibly and you know your mouse
wheel did something. In firefox, at least on mine, there's virtually
no feedback until seconds later when the new tiles start loading.
On the regular old google maps, they provide a little box-getting-
larger (or smaller) animation so you know your mouse wheel did
something, but on my google maps api v3 app ... nothing.
I tried this, but the animation usually happens long after the new
tiles loaded. It's not useful to give the feedback after the zoom
changes...
google.maps.event.addListener(map, 'zoom_changed', function()
{
var thisZoom = map.getZoom();
// this is the right idea, but happens way after the zoom,
aka useless
if( currentZoom < thisZoom ) {
// going in
anim_circle.setMap(map);
anim_circle.setCenter(map.getCenter());
anim_circle.setRadius(50);
setTimeout(function(){
anim_circle.setCenter(map.getCenter());
anim_circle.setRadius(100);
setTimeout(function(){
anim_circle.setCenter(map.getCenter());
anim_circle.setRadius(200);
setTimeout(function(){
anim_circle.setMap(null);
}, 150);
}, 150);
}, 150);
[...snip...]
Is there away to turn on some feedback — if there is, I can't find it
— or failling that, is there some way to hook an zoom event shortly
before the zoom actually happens?
