[OpenLayers-Users] GeoJSON filter function

[Adrián Ribao Martínez]

Hello,

you are right, my mail wasn't clear. Whant  I wanted to do is change the icon of the feature in function of an attribute. I thought that the filter funcion would help me to do that but then I discovered this solution:

var style = new OpenLayers.Style({
     'pointRadius': 10,
     'externalGraphic': '${icon}'
     });

which is much better.

Anyway, I like to know how could I use the filter funcion of the GeoJSON.read method.

http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLayers/Format/GeoJSON-js.html#OpenLayers.Format.GeoJSON.read

" This can be used to reform generic objects into instances of classes, or to transform date strings into Date objects."

I have been testing the filter argument passing a function, but I don't know the arguments and it didn't work. I'd like to know how could I transfrom date strings for example.

This won't work:
geojson_format.read(data, "FeatureCollection", function(e){alert(e); return e;})


Thank you.
