Learn more about the parameters you can use in the documentation. Query a FeatureLayer. Add a simple popupTemplate to each graphic to show some trail information when they are clicked. The main difference between client-side and server-side queries is that client-side querying is only possible after the feature layer is added to a map and the attributes are present. Query expressions are used in ArcGIS to select a subset of features and table records. Notice that only the features that match the query are displayed. Notice that all of the features draw because the layer is added to the map, but only the features returned from the query are added to the graphics layer. 5. Define an addGraphics function that will be used later to accept the return values from a query and add the results to the graphics layer. The graphics layer will be used to draw the features returned from the query. When the features are returned, pass the results to the addGraphics function. Try clicking on the map to see the features selected. Learn more about the parameters you can use in the documentation. Since features can only be queried after the layer is loaded, use whenLayerView to ensure the layer is ready and is not being updated. //queryFeatureLayer(view.center, 1500, "intersects"); //queryFeatureLayer(event.mapPoint, 1500, "intersects"); //queryFeatureLayer(view.center, 1500, "intersects"), //queryFeatureLayer(event.mapPoint, 1500, "intersects"), // Only return features for the feature layer. As a service editor, ArcGIS Pro supports a wide range of geodatabase datasets and capabilities from supported databases. When the view is ready, call the queryFeatureLayer function and pass in the center of the view, 1500 as the distance in meters, and intersects as the spatial relationship operator to use. In the require statement, add a reference to the FeatureLayer, GraphicsLayer and Graphic modules. This will search for and display features in the center of the map. Hosted feature layers are layers that have been published to ArcGIS Online. I am developing a web application (with ArcGIS Javascript 4.15) where I can click on a property.
