Zooming to query result extent

SteveMacLean

I am trying to zoom to the extent of a query I have.  I am having a problem when I call esri.graphicsUtils.graphicsExtent(resultFeatures) to get the extent.  It is returning NaN.  It works for one query I have that returns 42 records but for all the other queries I have it doesn't work.  

       queryTask.execute(query, function (featureSet) {
            var resultFeatures = featureSet.features;
            var myFeatureExtent = esri.graphicsUtils.graphicsExtent(resultFeatures);
            map.setExtent(myFeatureExtent); 
               var layerDefinitions = [];
               layerDefinitions[0] = queryString;
               //siteslayer.setLayerDefinitions(layerDefinitions);
          
         });

Any help would be appreciated.

Thanks

Steve

For future references... It's 2020 and I'm having the same issue you described using graphicsUtils.graphicsExtent with a point layer. I develop using js api version 3.x. Turns out, that for some reason one feature in the array returned from the REST query is coming with the following geometry:

{
  "geometry": {
    "x": "NaN",
    "y": "NaN",
    "spatialReference":  ...
  },
  "attributes": {

     ...

  }
}

Our users add points to this layer using Arcmap 10.5 and Arcmap 10.7 and I couldn't find out why sometimes this null geometry happens.

If you query the database to view this bad registry with sqldeveloper, you will find some null data inside shape column:

At least, that was what happened here. I would recomend checking the array for NaN data before using graphicsUtils.graphicsExtent to filter out bad data like this:

//note that NaN here is a string

var goodFeatures = features.filter(f => f.geometry.x === "NaN" || f.geometry.y === "NaN");

var extent = graphicsUtils.graphicsExtent(goodFeatures)

When I set the map with a bad extent, the map simply disapear and breaks the app.
