Identify Task on multiple layers- return all results to one InfoWindow

Den-GIS — Sat, 11 Dec 2021 21:12:47 GMT

Hi everyone

I try to show all results of several layers immediately in an InfoWindow without navigating over the arrow in the top right corner of InfoWindow (next / previous feature layer). Is that possible?
As a test, I use the following example

<!DOCTYPE html>
<html>
 <head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
 
 <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no">
 <title>Identify with Popup</title>
<link rel="stylesheet" href="https://js.arcgis.com/3.27/esri/css/esri.css">
 <style>
 html, body, #map {
 height:100%;
 width:100%;
 margin:0;
 padding:0;
 }
 </style>
<script src="https://js.arcgis.com/3.27/"></script>
 <script>
 var map;
require([
 "esri/map",
 "esri/InfoTemplate",
 "esri/layers/ArcGISDynamicMapServiceLayer",
 "esri/symbols/SimpleFillSymbol",
 "esri/symbols/SimpleLineSymbol",
 "esri/tasks/IdentifyTask",
 "esri/tasks/IdentifyParameters",
 "esri/dijit/Popup",
 "dojo/_base/array",
 "esri/Color",
 "dojo/dom-construct",
 "dojo/domReady!"
 ], function (
 Map, InfoTemplate, ArcGISDynamicMapServiceLayer, SimpleFillSymbol,
 SimpleLineSymbol, IdentifyTask, IdentifyParameters, Popup,
 arrayUtils, Color, domConstruct
 ) {
var identifyTask, identifyParams;
var popup = new Popup({
 fillSymbol: new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID,
 new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,
 new Color([255, 0, 0]), 2), new Color([255, 255, 0, 0.25]))
 }, domConstruct.create("div"));
map = new Map("map", {
 basemap: "satellite",
 center: [-83.275, 42.573],
 zoom: 18,
 infoWindow: popup
 });
map.on("load", mapReady);
var parcelsURL = "https://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/Parcels/MapServer";
 map.addLayer(new ArcGISDynamicMapServiceLayer(parcelsURL,
 { opacity: 0.55 }));
function mapReady () {
 map.on("click", executeIdentifyTask);
 //create identify tasks and setup parameters
 identifyTask = new IdentifyTask(parcelsURL);
identifyParams = new IdentifyParameters();
 identifyParams.tolerance = 3;
 identifyParams.returnGeometry = true;
 identifyParams.layerIds = [0, 2];
 identifyParams.layerOption = IdentifyParameters.LAYER_OPTION_ALL;
 identifyParams.width = map.width;
 identifyParams.height = map.height;
 }
function executeIdentifyTask (event) {
 identifyParams.geometry = event.mapPoint;
 identifyParams.mapExtent = map.extent;
var deferred = identifyTask
 .execute(identifyParams)
 .addCallback(function (response) {
 // response is an array of identify result objects
 // Let's return an array of features.
 return arrayUtils.map(response, function (result) {
 var feature = result.feature;
 var layerName = result.layerName;
feature.attributes.layerName = layerName;
 if (layerName === 'Tax Parcels') {
 var taxParcelTemplate = new InfoTemplate("",
 "${Postal Address} <br/> Owner of record: ${First Owner Name}");
 feature.setInfoTemplate(taxParcelTemplate);
 }
 else if (layerName === 'Building Footprints') {
 console.log(feature.attributes.PARCELID);
 var buildingFootprintTemplate = new InfoTemplate("",
 "Parcel ID: ${PARCELID}");
 feature.setInfoTemplate(buildingFootprintTemplate);
 }
 return feature;
 });
 });
// InfoWindow expects an array of features from each deferred
 // object that you pass. If the response from the task execution
 // above is not an array of features, then you need to add a callback
 // like the one above to post-process the response and return an
 // array of features.
 map.infoWindow.setFeatures([deferred]);
 map.infoWindow.show(event.mapPoint);
 }
 });

Denis,

You have to manually set the infoWindows content:

<!DOCTYPE html>
