Is there a way to make my map icons scale in size with zoom instead of being a static 38x38? If CSS can achieve this, I'm open to that option as well. It seems like it would also involve iterating through all markers, but I haven't been able to figure out how to do that.
Appreciate any help in advance.
All the markers should be within the DOM, each having its own "pane" identified by the class name leaflet-pane leaflet-marker-pane. The markers themselves must have at least the class leaflet-marker-icon.
You can access them using standard DOM queries like querySelectorAll. You might want to explore if there are any plugins available that cater to your specific needs; Leaflet has a variety of plugins in its ecosystem.
Unraveling the enigma of the XY problem, you find yourself pondering over adjusting marker sizes according to the zoom level. Instead of taking the straightforward route, you contemplate iterating through markers only to hit a dead end. Seeking guidance on this conundrum leads you to inquire about another problem.
The query arises: how can one dynamically alter the size of marker icons based on the zoom level?
Diverse approaches exist to tackle this issue.
One method involves binding an event handler to the map's zoomend event and navigating through each marker within it. This can be accomplished by utilizing map.eachLayer(...), verifying if the layer represents a marker (lyr instanceof L.Marker), and updating its L.Icon.
An alternate strategy includes linking an event handler to the zoomend event of the map for each individual marker, similar to the following:
for (i in data) {
...
var marker = L.marker(data[i].coords, ...);
map.on('zoomend', function() {
if (map.getZoom() > 15) {
marker.setIcon(...);
} else {
marker.setIcon(...);
}
});
}
A more innovative approach entails leveraging Leaflet.ZoomCSS, which modifies the map's CSS classes based on the zoom level, enabling you to adjust styling accordingly.
