Marker Animations With setTimeout()

  • google.maps.Marker is deprecated, withgoogle.maps.marker.AdvancedMarkerElement being the recommended replacement.

  • This example demonstrates usingwindow.setTimeout() to animate markers dropping onto the map sequentially.

  • A "Drop Markers" button triggers the animation, placing markers at predefined neighborhood locations.

  • Sample code is provided in TypeScript and JavaScript, alongside CSS and HTML for styling and structure.

As of February 21st, 2024 (v3.56), google.maps.Marker is deprecated. We encourage you to transition to the newgoogle.maps.marker.AdvancedMarkerElement class. Advanced markers provide substantial improvements over the legacygoogle.maps.Marker class. The minimum version of the Maps JavaScript API withgoogle.maps.marker.AdvancedMarkerElement is 3.53.2. At this time, google.maps.Marker is not scheduled to be discontinued.
