Removing Markers
AI-generated Key Takeaways
This example demonstrates how to add, hide, show, and delete markers on a Google Map using the Maps JavaScript API.
Markers are added to the map when the user clicks, and stored in an array for management.
Users can interact with buttons to control the visibility and existence of markers on the map.
The provided code snippets include implementations in both JavaScript and TypeScript.
While
google.maps.Markeris deprecated, it is currently still functional, and this example uses it for demonstration purposes.
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 creates a map where each click by the user creates a marker. Clickthe buttons to hide or delete all of those markers.
