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.
