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.
