How to change fillColor due a field value

Question

I have a map with some features, but I want to shoe them depending on al field.

May be

if [fieldname] = 0 --> color = RED else --> color = blue

Could anyone give a clue where to start?

Searching at leaflet documentation I managed to program

function getColor(d) {
    return d = 0 ? '#3182bd' :
           d = 1 ? '#31a354' :
                    '#FFEDA0';
}

function style(feature) {
return {
        fillColor: getColor(feature.properties.*fieldname*),
    };

}

But I'm not sure how to integer it, if I'm on the way or there's something easier with gvnix

Thanks all Javier

In your gvNIX view you can customize the symbol used to draw a geometry using the attribute fnAjustRender of entity-field tagx. Using this method you must declare a script in .jspx page and register it in the attribute.

By example, in show.jspx entity fied definition you should change:

....
<layer:entity-field clusterize="false" 
        fnAjustRender="myJSFunction"   .... z="user-managed"/>
....

Then create a myJSFunction in jspx like this:

<script>
  function myJSFunction(gvmap, layerId, fieldName, 
       featurePk, leafletLayer, featureData, isSelected) {

      var iconColor = "white";
      if (featureData.propName == 1) {
        iconColor = "red";
      } else {
        iconColor = "blue";
      }
      var iconMarker = L.AwesomeMarkers.icon({
                "icon" : icon,
                "prefix" : prefix,
                "markerColor" : markerColor,
                "iconColor" : iconColor
            });
       leafletLayer.setIcon(iconMarker);
       return leafletLayer;
  }

</script>
