Hi! Is it normal that the IdentifyTask returns features even if the layer is not visible? I see in the documentation that the layerOption parameter in the IdentifyParameters should define if the IdentifyTask will return feature for visibile layer only. However, this parameter seem not working. The popup is displayed even if the layer is not visible as shown below. The image and code below are taken from the documentation sample codes script > require ( [ "esri/Map" , "esri/views/MapView" , "esri/layers/TileLayer" , "esri/tasks/IdentifyTask" , "esri/tasks/support/IdentifyParameters" , "dojo/_base/array" , "dojo/on" , "dojo/dom" , "dojo/domReady!" ] , function ( Map , MapView , TileLayer , IdentifyTask , IdentifyParameters , arrayUtils , on , dom ) { var identifyTask , params ; // URL to the map service where the identify will be performed var soilURL = " https://services.arcgisonline.com/arcgis/rest/services/Specialty/Soil_Survey_Map/MapServer " ; // Add the map service as a TileLayer for fast rendering // Tile layers are composed of non-interactive images.

now I found a better way: you call: // .allSublayers is a flat collection of all children layer, including parent folder _current_visible_layer_id_array = getVisibleLayerIds(_map_image_layer.allSublayers); function getVisibleLayerIds(flat_layer_collection){ // layer is collection of all kinds of layers. find the visible one var ___array = []; flat_layer_collection.forEach(function(item, i){ console.log("flat_collection_forEach - item: ====== >",item ) if (item.sublayers) { // if item.sublayers is NOT null, means, item have children sulayer or layers. // filter out } else { // sublayer is null if (item.visible) { ___array.push(item.id); } else { ___array.push(-1); } } }); return ___array; } // getVisibleLayerIds

Your code only works for single level sublayers, DOES NOT work when multiple level of sublayers, For example, a sublayers have children sublayers, etc.... 2 level deep sulayers..... You have to use recursive to solve the multiple deep level sublayers..... Here is my working code: var _current_visible_layer_id_array = [] // you call this method recursive_nestedLayer(map,_map_image_layer.sublayers); // then you set params.layerIds = _current_visible_layer_id_array // now it works. // *********************** get current visible layer *********************** /* // https://community.esri.com/thread/192627-jsapi-v43-identifytask-returns-feature-even-if-layer-is-not-visible // only works when layer NOT have nest sublayers. Only 1 level, function getVisibleLayerIds(map, layer){ if (layer.sublayers){ return layer.sublayers.filter(sublayer => sublayer.visible).map(sublayer => layer.sublayers.indexOf(sublayer)); } else { return layer.visible ? [map.allLayers.indexOf(layer)] : [-1]; } } */ // for nested sublayer, use recursive function recursive_nestedLayer(map, _nestedLayer){ _nestedLayer.forEach(function(item, i){ if (item.sublayers){ // recursive function deep 1 level recursive_nestedLayer(map, item.sublayers); }else { console.log('-low-level-item',item ) if (item.visible){ console.log("visible !!!!") // map.allLayers.indexOf(item), not work, maybe lost layer handle, instead use item.id works. //_current_visible_layer_id_array.push(map.allLayers.indexOf(item)); _current_visible_layer_id_array.push(item.id); } else { _current_visible_layer_id_array.push(-1); } } // if }); } //recursive_nestedLayer // *********************** end ********************** get current visible layer ***********************

Did you ever log a bug with Esri on this? This seems to still be an issue at 4.17. Although, I wonder if it is a bug or a flaw in the logic. When creating a new IdentifyTask you just specify a url. It isn't really tied to the layer at all. So how would it know if the layer is visible or not? It seems like we are missing something.

MaximeDemers

Doing that, it wont work when the layer is visible...

What you'll have to do is set the layerIds property to -1 (setting it to "[]" doesn't work, like it did in 3.x)

params = new IdentifyParameters();
params.tolerance = 3;
params.layerIds = [-1];
params.layerOption = "top";
params.width = view.width;
params.height = view.height;‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Thats not what the doc says about the layerOption "top" paramerer: Only the top-most VISIBLE layer is identified.

Anyway setting the layerOption to "visible" does not make any difference. You can try directly in the sample code sandbox

ThomasSolow

By default it looks like identify is run on the top layer only, regardless of client layer visibility. You can change this using the identify params. For instance if you wanted to run identify only on visible layers, you could set the "layerOption" property on the params to "visible."

IdentifyParameters | API Reference | ArcGIS API for JavaScript 4.3

If you want to get specific about which layers to query, you can pass an array of layerIds in as the "layerIds" property.
