The control triggers "featuresselected" events when features are received.
var getFeatures = new OpenLayers.Control.GetFeature({
box: true,
click: false,
multiple: true,
protocol: new OpenLayers.Protocol.HTTP({
url: '/obj',
format: new OpenLayers.Format.GeoJSON(),
params: {
limit: 2000
}
}),
eventListeners: {
featuresselected: function(e) {
// do something with e.features
}
}
});
