google.maps.Markeris deprecated, withgoogle.maps.marker.AdvancedMarkerElementbeing the recommended replacement.This example demonstrates using
window.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.
This example useswindow.setTimeout() to place markers on the mapconsecutively rather than all at once when aDrop Markers button isclicked.
