Edit geometry, single feature

williamcarr

I have a single feature that represents a piece of machinery that needs to have it's geometry updated. I would like it to be able to be place by an input lat/lon via input text box. I was wondering what the best logic for this would entail.

How would I select a single feature for geometry update? An array?

Any help/guidance would be appreciated.

no worries.

1. make sure to take advantage of either the selectFeatures() callback or the corresponding event listener ("selection-complete") when you'd like to get a reference to a specific feature to update.
2. don't bother instantiating a new Graphic object.  just use the mapClick to set graphic.geometry on what's already been selected.  (because you don't want to overwrite or blow away the existing attributes.)

map.on("click", function(evt) {   featureLayer.selectFeatures(query, FeatureLayer.SELECTION_NEW, function(results) {     //use the method callback to dig into the results and update its geometry                             results[0].geometry = evt.mapPoint;                 //pass the entire array (in this case one feature) back to the server     featureLayer.applyEdits(null, results, null);                 //refresh the layer to make sure the edit was successful     featureLayer.refresh();               });         });

here's a working fiddle
