I have already found Undoing last point when drawing linestring in OpenLayers 3? (with working Plunker) but it can't undo misclicks when drawing polygon. So what I want is remove last drawing.

Does anyone know how to do that?

You can use something like this -

var features = vectorSource.getFeatures();
var lastFeature = features[features.length - 1];
vectorSource.removeFeature(lastFeature);

Note that you need to vectorSource.getFeatures() every time you want to remove the last feature or use it in a function.

  • Hey this works great for me. DO you any idea about redo that feature again. Sep 20, 2018 at 11:41
  • vectorSource.addFeature(lastFeature) should work. If you are removing multiple features and want to redo them, may be you should store the features somewhere before you remove them. Sep 21, 2018 at 10:32
  • this removeFeatures actually deletes feature, so on that index we get undefined value. Sep 21, 2018 at 11:30
  • Oh. Clone the feature then? var cloneFeature = lastFeature.clone(); Sep 21, 2018 at 11:44
