You have to actually load the GeoJSON features into the layer.
First, look at the following examples:
http://openlayers.org/dev/examples/geojson-reprojected.html
http://openlayers.org/dev/examples/cartodb-geojson.html
They both use a Fixed strategy which is the best one if you want to load
your data once and have it in a static file or known URL.
You would add your style definition to the vector layer definition they
present in these examples and then you would have a layer with features
to be symbolized.

Hello,
I have some features in GeoJSON format I want to display, so I did this:
[code]
var vectorLayer = null;
var vectorStyle =
{
graphicName: 'square',
strokeColor: '#222',
fillColor: '#222'
};
var styleDefault = OpenLayers.Util.applyDefaults(
vectorStyle,
OpenLayers.Feature.Vector.style['default']
);
vectorLayer = new OpenLayers.Layer.Vector('search',
{
styleMap: new OpenLayers.StyleMap(
{
'default': styleDefault
}
),
displayInLayerSwitcher: true
}
);
[/code]
but they don't appear in the map, my question is if this is enough to
get the features displayed or do I need something else there? if this
is enough, I should think that this problem is about how the features
are being read by OL. In fact, this doesn't work either:
var ll = new OpenLayers.LonLat(feature.geometry.x, feature.geometry.y);
mapPanel.map.setCenter(ll);
I get:
feature is not defined
[Break On This Error]
var ll = new OpenLayers.LonLat(feature.geometry.x, feature.geometry.y);
why should this happen? thanks in advance
