ArcGIS Maps SDK for JavaScript, get the number of items returned after applying a filter (client-side)

I am newbie to ArcGIS Maps SDK for Javascript.

I have done a filter by attributes (from user selection) on client-side. It works right, but I would like to show a message if the filter doesn't return any item. Is it possible with any method with my approach or should I change it?

Here is my code : https://codepen.io/gisdevelopment/pen/OJozLzw

Hi there,

You will have to query the features on the layer view once you change the layer view's feature filter. You can do it as shown below:

// Get a query object from the filter's current configuration const queryParams = earthquakesLayerView.filter.createQuery(); earthquakesLayerView.queryFeatures(queryParams) .then(function(results){ console.log("results", results.features); });
