I have an ol.source.ServerVector with several polygons drawn as features. I'd like for the map to zoom to the extent of the selected polygon upon selection, but I'm hitting a wall.

I was able to find this post that helped with zooming to all of the features in the source, but not the selected feature specifically


var extent = source.getExtent();

That works great to zoom to all of my polygons, but I can't seem to find any way to only use the selected feature's extent.

    var extent = this.array_[0].getGeometry().getExtent();

This is inside of an on.('change:length') function, so the 'this' is the selected collection. It might not be the "correct" way to do it, but it seems to be working as desired, so hopefully this helps someone out down the line.

    This did help me! But a little update, in ol.Collection, you should interact with the internal array via the getters, ie: getLength() and item(0). Also, OL has consolidated fitExtent and fitGeometry with fit, so just use that on either the geometry or extent.

  • fitExtent is deprecated. use view.fit() instead.

  • @AdamAL : Just like @ janechii has already commented on Jul 10 '16.

  • I suppose I lack reading skills. I missed that. But then again maybe I missed it due to over-verbosity.
