Leaflet WMS Set points Transparent - leaflet

Question

I am using Geoserver to display a WMS format Layer points on leaflet.
var owsrootUrl = 'http://localhost:8081/geoserver/cite/wms';
var defaultParameters = {
service : 'WFS',
version : '2.0',
request : 'GetFeature',
transparent: true,
typeName : 'cite:transacthcmgis_salesaggregated',
outputFormat : 'json',
format_options : 'callback:getJson',
SrsName : 'EPSG:4326'
};
var geojsonMarkerOptions = {
radius: 0,
fillColor: "#ff7800",
color: "#000",
weight: 0,
opacity: 0,
fillOpacity: 0.0
};
var parameters = L.Util.extend(defaultParameters);
var URL = owsrootUrl + L.Util.getParamString(parameters);
var ajax = $.ajax({
url : URL,
dataType : 'json',
jsonpCallback : 'getJson',
success : function (response) {
L.geoJson(response, {
style: function(geoJsonPoint, latlng) {
return L.marker(latlng, geojsonMarkerOptions);
},
onEachFeature: function (feature, url) {
popupOptions = {maxWidth: 250};
url.bindPopup("<b>Pharmacy Name:</b> " + feature.properties.customername_clients
+ "<br><b>adm0_zscore: </b>" + feature.properties.adm0_zscore
+ "<br><b>adm1_zscore: </b>" + feature.properties.adm1_zscore
+ "<br><b>adm2_zscore: </b>" + feature.properties.adm2_zscore
+ "<br><b>adm3_zscore: </b>" + feature.properties.adm3_zscore
,popupOptions);
}
}).addTo(map);
zscore.on('add', function(evt) {
if (!map.hasLayer(geoJSON)) map.addLayer(geoJSON);
});
zscore.on('remove', function(evt) {
if (map.hasLayer(geoJSON)) map.removeLayer(geoJSON);
});
}
});
I am setting my style for the stroke to 0 and my fill opacity to 0.0 and it still returns me the default leaflet point icon as you can see in this picture?
How i can display them "transparent"?

Answer 1

Let me quote the Leaflet documentation about L.GeoJSON's pointToLayer property, emphasis mine:
A Function defining how GeoJSON points spawn Leaflet layers. It is internally called when data is added, passing the GeoJSON point feature and its LatLng. The default is to spawn a default Marker.
Note that the default pointToLayer callback ignores the value of the style option passed to the L.GeoJSON constructor.
I guess you'll want to provide a custom pointToLayer callback, so that poitn features spawn L.CircleMarkers instead. There's information on how to do so in the Leaflet GeoJSON tutorial.
