Select nearest feature?

[Infiniverse]

The default SelectionInteraction is a bit tricky to use - quite often it is not easy to click on a feature, especially if it's a narrow line. One approach to resolving this is outlined in:

http://jsfiddle.net/XfEmn/

It sets things up so that when a selection is made, the nearest feature is selected instead, which makes it much easier to select features.

Is this an approach could be integrated into v-ol3?

(function() {

//util func for creating some poitn features
function createFeatures () {
    var points = [
        {"lon": 10, "lat": 60},
        {"lon": -10, "lat": 40},
        {"lon": 30, "lat": 30},
        {"lon": 20, "lat": 20}
    ];

    return _.map(points, function(point, idx) {
        var p = new OpenLayers.Geometry.Point(point.lon, point.lat).transform(new OpenLayers.Projection("EPSG:4326"), new OpenLayers.Projection("EPSG:900913"));
        return new OpenLayers.Feature.Vector(p, {"index": idx});
    });
}

var map = new OpenLayers.Map({
    div: "map",
    theme: null,
    
    layers: [
        new OpenLayers.Layer.OSM("OpenStreetMap", null, {
            transitionEffect: "resize"              
        })
    ],
    center: new OpenLayers.LonLat(0, 0),
    zoom: 1
}); 

var nodeLayer = new OpenLayers.Layer.Vector();
nodeLayer.addFeatures(createFeatures());
map.addLayer(nodeLayer);

var selectFeatureControl = new OpenLayers.Control.SelectFeature(nodeLayer);
map.addControl(selectFeatureControl);

map.events.register("click", map,  function(e) {
    selectFeatureControl.deactivate();
    var pos = this.getLonLatFromPixel(e.xy);        
    var point =  new OpenLayers.Geometry.Point(pos.lon, pos.lat);
    var closest =_.min(nodeLayer.features, function(feature) {
        return feature.geometry.distanceTo(point);
    });
    selectFeatureControl.activate();
    selectFeatureControl.select(closest);        
});

}());
