Thanks, Jim. Your solution is elegant.

The problem was that the array I was building considered the numbers as string rather than integer, so I had to use parseInt. I should have included this code in my original post. I thought I was misunderstanding the subLayerIds String[] type. function getPrintLegendLayerPolygons() { var arrayLegendPolygons = [], visiblePrintSublayerPolygons = [], arrayValue = []; arrayLegendPolygons = getVisibleLayersPolygons().sort(); // Exclude some Polygon layers from the legend that are self-explanatory if (arrayLegendPolygons.length > 0) { for (var i = 0; i < arrayLegendPolygons.length; i++) { if (arrayLegendPolygons == indexPoly_CountyBdry || arrayLegendPolygons == indexPoly_MuniBdry || arrayLegendPolygons == indexPoly_Waterbody) { } else { visiblePrintSublayerPolygons.push(parseInt(arrayLegendPolygons,10)); } } arrayValue = visiblePrintSublayerPolygons; } else { arrayValue = []; } return arrayValue; } function getVisibleLayersPolygons() { visiblePolygons = []; $('[name="layerVisibility"]:checked').each(function () { if ($(this).is(':checked')) { var layerid = $(this).attr('id').split(":"); // layerid[1] is LayerIndex in the Map Service // layerid[3] is service layer (e.g., points, lines, polygons) if (layerid[3] == 'Polygons') { visiblePolygons.push(layerid[1]); } } // end if stmt }); return visiblePolygons; }

I have successfully gotten the PrintTask to work with multiple map services with a legend. By hard-coding the list of legendLayer.subLayerIds, it works. However, I want to look up the visible layers in the map and return an array of layer indexes and assign that array to the legendLayer.subLayerIds for each map service. I have tried various things such as (1.) using a loop and pushing each array value into legendLayer.subLayerIds, (2.) using brackets (e.g., legendLayer.subLayerIds = [returnedArray], (3.) creating a string instead of an array with commas in between each layer index (e.g., "[38,44]"). Option (3.) actually works, but even if I pass a blank string (e.g., "[ ]"), all of the visible layers for that map service are included in the print legend. Here is the code that works with the hard-coded values for the legendLayer.subLayerIds: <!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"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black-translucent"> <meta name="mobile-web-app-capable" content="yes"> <title>ArcGIS dynamic and tile layers using Popup and InfoTemplates</title> <script type="text/javascript" src="../jquery/jquery-1.11.3.min.js"></script>  <script type="text/javascript" src="../jquery/jquery-ui-1.10.4/ui/jquery-ui.js"></script> <link rel="stylesheet" href="https://js.arcgis.com/3.20/esri/css/esri.css"> <style> html, body, #ui-esri-map { width: 100%; height: 100%; margin: 0; padding: 0; } .esriPopup .titlePane { text-shadow: none; } .esriPopup .titleButton.next { right: 40px; } .esriPopup .titleButton.prev { right: 53px; } .demographicInfoContent { padding-top: 10px; } .demographicInnerSpacing { display: inline-block; width: 8px; } .demographicNumericPadding { width: 90px; display: inline-block; text-align: right; } #info{ top: 0px; right: 0px; position: absolute; z-index: 99; opacity: 0.9; background-color: whitesmoke; border-bottom-left-radius: 8px; padding: 0px 0px 0px 10px; } #infoPrint{ bottom: 5px; left: 5px; position: absolute; z-index: 99; opacity: 0.9; background-color: lightpink; border-top-right-radius: 8px; padding: 10px 10px 20px 10px; width: 20%; } </style> <script src="https://js.arcgis.com/3.20/"></script> <script> $(document).ready(function () { var map; // layer indexes in the map services var indexPoint_StormwaterOuterZoom = 34; var indexPoint_StormwaterMiddleZoom = 35; var indexPoint_StormwaterCloseUpZoom = 36; var indexPoint_ControlPts = 1; var indexPoint_FiberPts = 9; var indexPoint_ReferencePts = 11; var indexPoint_SchoolBusStopsOSPI = 19; var indexPoint_AvistaPoleStructure = 28; var indexPoint_Shop = 5; var indexLine_PriorityArray = 13; var indexLine_RoadSegments = 38; var indexLine_Railroad = 41; var indexLine_Waterline = 44; var indexPoly_NoTrucks = 32; var indexPoly_CountyBdry = 13; var indexPoly_Parcels = 53; var indexPoly_MuniBdry = 83; var indexPoly_Waterbody = 27; require([ "dojo/dom-construct", "esri/Color", "esri/dijit/Popup", "esri/InfoTemplate", "esri/dijit/Legend", "esri/layers/ArcGISDynamicMapServiceLayer", "esri/map", "esri/tasks/PrintTask", "esri/tasks/PrintTemplate", "esri/tasks/PrintParameters", "esri/tasks/LegendLayer", "esri/config", "dojo/parser", "dojo/domReady!" ], function ( domConstruct, Color, Popup, InfoTemplate, Legend, ArcGISDynamicMapServiceLayer, Map, PrintTask, PrintTemplate, PrintParameters, LegendLayer, esriConfig, parser ) { parser.parse(); //This sample may require a proxy page to handle communications with the ArcGIS Server services.

The reason the ShowIdentifyResults was taking so long to display on the map was because it was creating results for all layers in each of the dynamic map service layers. To only ShowIdentifyResults for the visible layers, I modified the createIdentifyParams function with this: var visLayers = layer.visibleLayers; if (visLayers !== -1) { var subLayers = []; for (var i = 0; i < visLayers.length; i++) { subLayers.push(visLayers); } // end for stmt alert("idParams.layerIds=" + subLayers); idParams.layerIds = subLayers; } else { idParams.layerIds = []; }

‎06-02-2017

Ah, that makes sense. Thank you. Why does the code then go on and take forever for the identify popup to appear? Why does the identify popup display all layers that were clicked at a point on the map, and not just the visible layers?

I used the sample cleverly written in post Identify Sample and modified it by setting visible layers for only a few layers in each map service. However, when I click on the map, the identify brings up results for all the layers I clicked on even though they are not visible in the map. In this code snippet, the layer.visibleLayers[0] = 0,33,38,13. Can someone explain those results? function mapReady(map) { dojo.connect(map, "onClick", runIdentifies); pointsLayer.setVisibleLayers([33]); linesLayer.setVisibleLayers([38, 44]); polygonsLayer.setVisibleLayers([13, 27, 53, 62, 83]); } ... layers = dojo.filter(layers, function (layer) { if (layer.visibleLayers[0] !== -1) { return layer.getImageUrl && layer.visible } Can someone help me understand how multiple map services are handled in the identify task? For a single map service, the identifyParams.layerIds is set to the index values of the layers to identify. For multiple map services, is the identifyParams.layerIds set to the map url AND the index of the layer? How does the IdentifyTask know which index belongs with which map service? Thank you.

Below is how I am able to expand the LayerList automatically in the ArcGIS API for JavaScript 4.3. On an event click, I wanted the LayerList to automatically expand to show the sublayers within my MapImageLayer. In 3.x, two classes were replaced: one to expand the layerlist and another to change the icon. I am unsure how to change the attributes in the When using Inspect Element, I can see that the following attributes change in the html: 1. the title changes from "Expand" to "Collapse" and aria-expanded changes from" false" to" true" <div class="esri-layer-list__item-container"> <span tabindex="0" title="Expand" class="esri-layer-list__child-toggle" role="button" aria-expanded="false" aria-controls="layerListDiv_15afbb8a47b-object-23">...</span> 2. the hidden=" " is an element when the above elements are = Expand and false, respectively, and the hidden=" " is removed from when the above elements are = Collapse and true, respectively <ul class="esri-layer-list__list esri-layer-list__--independent" id="layerListDiv_15afbb8a47b-object-23" role="group" hidden=" ">...</ul> 3. the icon changes from <span class="esri-layer-list__child-toggle-icon--closed esri-icon-rigjht-triangle-arrow" aria-hidden="true"></span> to <span class="esri-layer-list__child-toggle-icon--opened esri-icon-down-arrow" aria-hidden="true"></span> Here is my code snippet: //********************************************* // Function Expand Layer List //********************************************* function expandLayerList() { // change aria-expanded var x = document.getElementsByClassName("esri-layer-list__child-toggle")[0].getAttribute("aria-expanded"); if (x == "false") { x = "true" document.getElementsByClassName("esri-layer-list__child-toggle")[0].setAttribute("aria-expanded", x); } // change title var y = document.getElementsByClassName("esri-layer-list__child-toggle")[0].getAttribute("title"); if (y == "Expand") { y = "Collapse"; document.getElementsByClassName("esri-layer-list__child-toggle")[0].setAttribute("title", y); } // change hidden var z = document.getElementsByClassName("esri-layer-list__list esri-layer-list__list--independent")[1].hasAttribute("hidden"); alert(z); if (z) { var h1 = document.getElementsByClassName("esri-layer-list__list esri-layer-list__list--independent")[1]; h1.removeAttribute("hidden"); } } // end expandLayerList function

I am trying to set the initial extent for my map that uses the ESRI "topo" basemap. My map service is in a different spatial reference, therefore, I am using the spatial reference of the basemap to set my min/max x/y values. However, whatever I set my extent values, the map either sets to zoom level 9 or 10 in the "topo" basemap. I tried using "fitExtent: true". When I comment out the 'basemap: "topo," statement, then the initialExtent works. Question: How can I override the zoom levels of the basemap when setting my initial Extent? my JavaScript: // wkid: 102100 or 3857 is the spatial reference of basemap // basemap url: https://services.arcgisonline.com/arcgis/rest/services/World_Topo_Map/MapServer var initialExtent = new esri.geometry.Extent( -13115148, 5969306, -13028889, 6120000, new esri.SpatialReference({ wkid: 3857 }) ); map = new Map("mapDiv", { basemap: "topo", sliderOrientation: "vertical", sliderPosition: "top-left", extent: initialExtent, fitExtent: true, sliderStyle: "small" }); //end map

‎01-27-2017

Thank you. It is similar to how I set up the regular definition query. var layerDefinitions = []; layerDefinitions[0] = "bridge_symbol = 'weight restr'"; allTravelImpactsLayer.setLayerDefinitions(layerDefinitions);

‎01-27-2017

Good idea! When I try setting the identify parameter layer definition, identifyParams.layerDefinitions[3] = "DateOn <= '" + ondate + "' AND DateOff >= '" + offdate + "'"; I get an error "0x800a138f - JavaScript runtime error: Unable to set property '3' of undefined or null reference" So, I found on another post to try setting the layer definition like this: identifyParams.layerDefinitions = { "3": "DateOn <= '" + ondate + "' AND DateOff >= '" + offdate + "'" }; I do not get an error, but the identify layer definition is not getting set.

I am using the ArcGISDynamicMapServiceLayer to load my layers into the map in ArcGIS API for JavaScript 3.19. I have set up the IdentifyTask, and it works great except for one problem. I allow the end-user to search on a date range which sets a definition query to only display those features. However, the identify popup includes those features that are being excluded using the definition query. How do I get an Identify popup for only those features that are visible because of the definition query?

I am using the IdentifyTask sample for 4.2 at https://developers.arcgis.com/javascript/latest/sample-code/tasks-identify/index.html However, I am using a MapImageLayer as my URL and when I try to perform the identifyTask.execute(identifyParams), the success promise isn't working. All I get is the "wait" cursor. I also tried defining my sublayers within my new MapImageLayer with id: values set as the same index values from the map service. The map service is in a different spatial reference than the ESRI basemap, if that makes any difference. Does identifyTask work with a MapImageLayer?

‎12-30-2016

Robert, Thanks for your response. You have answered other questions I have had on this forum, and I greatly appreciate it. I was able to get the view.popup.reposition(); to work once I removed the view.goTo code.
