QUESTION
This is related to a previous question: Leafletjs dynamically bound map to visible overlays.
I am now using the Leaflet.FeatureGroup.SubGroup
plugin with the Leaflet.markercluster
plugin. Trying to set map bound to all visible markers and marker clusters. I am using 3 co-ordinates to test:
ANSWER
Answered 2017-Jul-27 at 19:23If I understand correctly, you are puzzled because when one of your SubGroups has only 1 marker, the map.fitBounds
does not look to be executed?
In that case, that is simply the expected behaviour of the !southWest.equals(bounds.getNorthEast())
check: it avoids executing the next block when bounds
represents a null area, i.e. there is 0 or 1 marker into it.
By replacing the check by bounds.isValid()
, you avoid only the case when there is 0 marker, but in the case there is exactly 1 marker, it will allow executing the next block, therefore trying to fit bounds on a null area. In such case, Leaflet pans to that single marker and zooms to maxZoom
.
QUESTION
I want to implement marker clustering for multiple geoJSON layers. After some research, using Leaflet.FeatureGroup.SubGroup plugin looks like the solution I need.
How can I iterate over the geoJSON to dynamically add/remove Layer Groups from the map with current code sample I have provided?
