Question

I wish that a marker bounces for a few seconds and eventually stops automatically.. I am trying this code :

1. globalMarkers[i].setAnimation(google.maps.Animation.BOUNCE);
2. setTimeout(function() {
3.    globalMarkers[i].setAnimation(null)
4. }, 3000);

but for some reason, line 1 executes (hence marker will start bouncing) but the 3rd line returns the following error:

Uncaught TypeError: Cannot call method 'setAnimation' of undefined
        (anonymous function)

Any ideas what it could be?

This works fine (with a single global marker object)

    marker.setAnimation(google.maps.Animation.BOUNCE);

    setTimeout(function() {
        marker.setAnimation(null)
    }, 3000);

My guess is that you’re interating, and your setTimeout i is not in scope. Try this instead:

    for (var x = 0; x < 5; x++) {
        var marker = markers[x];
        marker.setAnimation(google.maps.Animation.BOUNCE);
        stopAnimation(marker);
    }


function stopAnimation(marker) {
    setTimeout(function () {
        marker.setAnimation(null);
    }, 3000);
}

There are some more creative solutions here:
