Hi,I'm working on multiple ArcGISDynamicMapServiceLayer IdentifyTask and i use this thread as a sample and it work. But i've some issue when i change basemap: "satellite" to basemap: "osm", identify popup didn't work.Thank<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <!--The viewport meta tag is used to improve the presentation and behavior of the samples on iOS devices--> <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"> <title>Identify with Popup</title> <link rel="stylesheet" href="http://js.arcgis.com/3.8/js/esri/css/esri.css"> <style> html, body, #map { height: 100%; width: 100%; margin: 0; padding: 0; } </style> <script>var dojoConfig = { parseOnLoad: true };</script> <script src="http://js.arcgis.com/3.8/"></script> <script> var map; var identifyTask, identifyParams, idPoint; var identifyResults; require([ "esri/map", "esri/dijit/Popup", "dojo/promise/all", "dojo/domReady!" ], function ( Map, Popup, All ) { var popup = new Popup({ fillSymbol: new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255, 0, 0]), 2), new dojo.Color([255, 255, 0, 0.25])) }, dojo.create("div")); map = new Map("map", { basemap: "osm", center: [-83.275, 42.573], zoom: 18, infoWindow: popup }); dojo.connect(map, "onLoad", mapReady); var landBaseLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/Parcels/MapServer", { opacity: .55 }); map.addLayer(landBaseLayer); var militaryLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://sampleserver6.arcgisonline.com/arcgis/rest/services/Military/MapServer", { opacity: .55 }); map.addLayer(militaryLayer); function mapReady(map) { dojo.connect(map, "onClick", runIdentifies); } function runIdentifies(evt) { identifyResults = []; idPoint = evt.mapPoint; var layers = dojo.map(map.layerIds, function (layerId) { return map.getLayer(layerId); }); layers = dojo.filter(layers, function (layer) { if (layer.visibleLayers[0] !== -1) { return layer.getImageUrl && layer.visible } }); //Only dynamic layers have the getImageUrl function.
