works great on .js file with Aptana studio 3; Thanks Kelly ... View more

I am trying to modify the gallery sample - Public Information Map - 2.0. I want to include a dynamic map layer in the layers.js that will always be the active layer for map click events to display attributes in an info window but not appear in the Layers Menu for turning its display on and off. (It will be totally transparent and I do not want the user to even know the layer exists.) I have figured out the transparency and active for click event part but not how to remove it from the drop down Layers Menu. I would appreciate any help to this struggling beginner. I also modified this template, and in the end, it was a huge pain, and I almost ended up redeveloping the entire app. If you look, there's probably a function that adds all layer variables to an array, then later, another function loops over the array adding each layer to the legend widget. Just stop the layer in question from being added to the array and your done. ... View more

from the api reference: "The name of the layer as defined in the map service." a -> ... id: "graphicsLayer4" console.log(featureLayer.name) - would return the name of the layer as defined in the service. Doesn't look like you can define name, only properties listed in the 'constructor detail' section of the api reference. ... View more

found the problem. I ended up setting up a query task onLoad that fills a graphicsLayer will transparent points. I know this is duplicate data since the feature layer is already loaded/displayed on the map. However, the onMouseOver is hooked to the graphicsLayer and the onClick is hooked to the feat. layer; for me, this allows for easy switching b/t the two. Identify button enabled remove graphicsLayer disconnect graphicsLayer onMouseOver connect map onClick Identify button disabled loop over TOC and check if the layer is visible add graphicsLayer connect graphicsLayer onMouseOver disconnect map onClick ...

i'm almost there... when the map loads, the onMouseOver listener is active. Simple popups are displayed, highlightgraphic added. OnMouseOut also works removing the highlightgraphic. When the identify toggle button is clicked, onMouseOver is no longer active and executeIdentifyTask fires... so far so good. However, if you try and click a point that was previously hovered on, executeIdentifyTask is not fired, but rather, only the simple popup is displayed?? any advice? TIA! //globals var featlayer; var identifyListener; var facilsHoverHandle; var facilsHoverHandleOut; function init() {     featlayer = new esri.layers.FeatureLayer("url",{         mode:esri.layers.FeatureLayer.MODE_ONDEMAND, id: 'facs',              outFields:["*"]     });     facilsHoverHandle = dojo.connect(featlayer, "onMouseOver", showHoverPopup);     facilsHoverHandleOut = dojo.connect(featlayer, "onMouseOut", hideHoverPopup); } function showHoverPopup(evt){         map.graphics.enableMouseEvents();         var infoTemplate = new esri.InfoTemplate(); infoTemplate.setTitle(evt.graphic.attributes.facil_name); infoTemplate.setContent("<b>${facil_name}</b>"); map.infoWindow.resize(245,125);    var highlightSym = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_SQUARE, 10,     new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID,     new dojo.Color([255,0,0]), 1),     new dojo.Color([0,255,0,0.25]));    evt.graphic.setInfoTemplate(infoTemplate);    var content = evt.graphic.getContent(); map.infoWindow.setContent(content); var title = evt.graphic.getTitle(); map.infoWindow.setTitle(title); highlightGraphic = new esri.Graphic(evt.graphic.geometry,highlightSym); map.graphics.add(highlightGraphic); map.infoWindow.show(evt.screenPoint,map.getInfoWindowAnchor(evt.screenPoint)); }   function hideHoverPopup(evt){         map.graphics.remove(highlightGraphic); } //toggles identify onClick and featlayer onMouseOver listeners on/off function activateIdentify(){      if (dijit.byId("tool_identify").checked) {   map.infoWindow.hide();   dojo.disconnect(featlayerHoverHandle);   dojo.disconnect(featlayerHoverHandleOut);              identifyListener = dojo.connect(map, "onClick", executeIdentifyTask);    } else {       dojo.disconnect(identifyListener);   facilsHoverHandle = dojo.connect(featlayer , "onMouseOver", showHoverPopup);   facilsHoverHandleOut = dojo.connect(featlayer , "onMouseOut", hideHoverPopup);    } } <button dojotype="dijit.form.ToggleButton" id="tool_identify" title="Identify"                         onclick="activateIdentify();" style="cursor:crosshair;">                         <img src="images/infoIcon.png" width="34px" height="34px" alt="" /> </button> ...

awesome. Thanks Derek! ... View more

i guess the short answer to why do i need identifyTask is because I saw this method in the samples. Now that I look back, the identifyTask seems to only be necessary if it's a dynamicLayer? There are multiple points atop each other at full scale, and when zoomed in, multiple layers can be selected, so I stuck with the deferred = identifyTask.execute() deferred.addCallback() then switch for each featureLayer name and set infoWindow accordingly. There are also several queryRelatedFeatures tasks for some of the layers. Do you have a sample of an identify tool, I've never seen one? Do you just use a dijit.form.button? thanks! ... View more

after some brainstorming, I decided to do away with the identifyTask and replace it with a findTask when a grid row click is detected. The existing code to process the response can remain exactly the same since both the identifyTask and findTask returns a dojo.deferred incase anyone's interested, here's the solution: function executeIdentifyTask(evt) {     if (evt.mapPoint == undefined){ //grid click, lets switch to a find task anchorPt = evt.geometry; siteCode = evt.attributes.site_code[0]; lids.push(0);   var findTask2 = new esri.tasks.FindTask("https://mydomain.com/MapServer/"); var fParams = new esri.tasks.FindParameters(); fParams.searchText = siteCode; fParams.returnGeometry = true; fParams.searchFields = ["site_code"]; fParams.layerIds = lids; //set lids to include only facil layer fParams.contains = false; var deferred = findTask2.execute(fParams);      }      else{ //map click; identifyParams.tolerance = 5; anchorPt = evt.mapPoint; //since LAYER_OPTION_VISIBLE only pertains to scale visibility, not TOC checked/not checked, we have to manually set the identifyParams.layerIds dojo.forEach(legendLayers, function(layer){   //layer must be checked in toc AND not be parcels, bndry or prtct;   if (layer.layer.visible === true && (!(layer.layer.id == "parcels" || layer.layer.id == "bndry" || layer.layer.id == "prtct"))){    lids.push(map.getLayer(layer.layer.id).layerId); //set lids to include all visible facilities   }   })        //click dependent identifyparams        identifyParams.layerIds = lids;                  identifyParams.width  = map.width;        identifyParams.height = map.height;        identifyParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_VISIBLE;           identifyParams.geometry = anchorPt;        identifyParams.mapExtent = map.extent;        var deferred = identifyTask.execute(identifyParams);     }     deferred.addCallback(function(response) {         //set esri.dijit.PopupTemplate for each layer     }); }; ...
