我正在使用OpenLayers v3.6(这很重要,因为我发现并且可能有效的大多数解决方案都适用于OpenLayers 2).

我有一个表,当我在该表中选择一行时,我想在OpenLayers地图上突出显示/选择相应的功能.所有要素都是同一矢量图层中的简单多边形(ol.geom.Polygon)(ol.layer.Vector).

我设置了这样的选择交互:

// there is a lot of other code here
...
addSelectListener: function() {
    this.SelectInteraction = new ol.interaction.Select({
        condition: ol.events.condition.singleClick,
        layers: function (layer) {
            // defines layer from which features are selectable
            return layer.get('id') == 'polygons_layer';
        },
        style: this.Style.Selected
    });

    // Map = ol.Map
    Map.addInteraction(this.SelectInteraction);
    this.SelectInteraction.on('select', this.selectPolygon, this);
}

...

selectPolygon: function(event) {
    var selectSrc = this.getSelectInfo(event);

    // some code that relies on selectSrc data
}

...

getSelectInfo: function (event) …
