I do this (uses prototype.js):
var vector_layer = new OpenLayers.Layer.Vector('A Layer',{
sphericalMercator: true,
});
new Ajax.Request("YOUR_URL_HERE", {
onSuccess: function(response){
route_json= new OpenLayers.Format.GeoJSON()
vector_layer.addFeatures(route_json.read(response.responseText));
}
}
);
However, for some reason it's not actually displaying on the map, even
though
map.zoomToExtent(vector_layer.getDataExtent()) zooms to where the
layer *should* be.

Shouldn't be needed.
