Control marker visibility by zoom level

  • This example demonstrates how to control the visibility of markers based on the map's zoom level.

  • By dynamically setting themarker.map property to either the map instance ornull, markers can be shown or hidden as the user zooms in or out.

  • The sample code utilizes theAdvancedMarkerElement class and listens to thezoom_changed event to adjust marker visibility accordingly.

  • You can view the marker visibility change by zooming in or out on the map provided in the sample.

This example shows controlling marker visibility by zoom level. See the markers'visibility change (begin by zooming out):

Note: Read theguide on using TypeScript and Google Maps.

JavaScript

constmapElement=document.querySelector('gmp-map');asyncfunctioninitMap(){// Request needed libraries.const{Map}=(awaitgoogle.maps.importLibrary('maps'));const{AdvancedMarkerElement}=(awaitgoogle.maps.importLibrary('marker'));constmarkerOptions=[{position:{lat:37.4239163,lng:-122.094},title:'This marker is visible at zoom level 15 and higher.',minZoom:14,},{position:{lat:37.4245,lng:-122.096},title:'This marker is visible at zoom level 16 and higher.',minZoom:15,},{position:{lat:37.4249,lng:-122.095},title:'This marker is visible at zoom level 17 and higher.',minZoom:16,},{position:{lat:37.425,lng:-122.0955},title:'This marker is visible at zoom level 18 and higher.',minZoom:17,},];constmarkers=[];for(const{position,title}ofmarkerOptions){constmarker=newAdvancedMarkerElement({position,title});mapElement.append(marker);markers.push(marker);}mapElement.innerMap.addListener('zoom_changed',()=>{letzoom=mapElement.innerMap.getZoom();for(leti=0;i <markers.length;i++){const{position,minZoom}=markerOptions[i];markers[i].position=zoom >minZoom?position:null;}});}initMap();
Note: The JavaScript is compiled from the TypeScript snippet.
