Openlayers3: Abort The Draw Interaction

i am using for my html a draw interaction for drawing routes manually // manual route creation event $('#createRoute').click(function() { // remove prev

Solution 1:

Wait until your feature is added to ol.source.Vector:

your_source.on('addfeature', function(event) {
    saveRoute(event);
    map.removeInteraction(draw);

    console.log("Map Interaction(Route): deactivated");
});
