Limit drop marker to feature

ITApplications

Hi

When zoomed in and the streets feature layer is available we are able to drop a graphic marker anywhere on the map.

I'd like to limit the graphic marker to be only able to drop it onto the feature (street) and not just anywhere on the map.

How can I do that?

This map will be used for reporting potholes on a street and the graphic will serve no other service other than visually showing (along with the popup that appears when you click on the feature) where someone has clicked to report the location of the pothole.

 

Thanks

// change this
if (!view.graphics.length) {
  // check if layer where you clicked
  // with hitTest
  view.hitTest(evt).then(({results}) => {
    if (results.length) {
      view.graphics.removeAll();
      view.graphics.add(graphic);
    }
  });
}

// to this
// check if layer where you clicked
// with hitTest
view.hitTest(evt).then(({results}) => {
  if (results.length) {
    view.graphics.removeAll();
    view.graphics.add(graphic);
  }
});
