Hi,I'm trying to add functionality to select a group of parcels as laid out in this example, and display queried information for those parcels in a popup info window. I've got it displaying the queried data in an infowindow correctly, and it highlights the correct parcel for the info being displayed, but I'm having issues highlighting every selected parcel. In the above example it sets the selection symbol with setSelectionSymbol(), but for whatever reason this isn't working for me, and I'm not exactly sure what I'm doing wrong.I've included the parts of my code that are relevant to my problem, including parts that deal with toggling the parcel layer on and off in a legend.Thank you for any help! If i can help clarify anything at all let me know! function init() { //initialize popup window var popup = new esri.dijit.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")); //add geometry service from server esri.config.defaults.geometryService = new esri.tasks.GeometryService("http://2501s-jjohnson:6080/arcgis/rest/services/Utilities/Geometry/GeometryServer"); //initalize map app.map = new esri.Map("map", { basemap : "satellite", center : [-111.924531, 40.611871], zoom : 13, infoWindow: popup }); //query parcel and show info in popup window function executeIdentifyTask(evt) { var query = new esri.tasks.Query(); query.geometry = pointToExtent(app.map,evt.mapPoint,10); var deferred = featureParcel.selectFeatures(query,esri.layers.FeatureLayer.SELECTION_NEW); app.map.infoWindow.setFeatures([deferred]); app.map.infoWindow.show(evt.mapPoint); console.log(evt.mapPoint); } //trigger feature layer parcel query if parcels are turned on function clickConnect(connect){ if(connect){ //perform the identify task on click clickHandler = dojo.connect(app.map, "onClick", executeIdentifyTask); }else{ //disconnect the click handler dojo.disconnect(clickHandler); clickHandler = null; } } //add parcel layer var parcels = new esri.layers.ArcGISDynamicMapServiceLayer("http://2501s-jjohnson:6080/arcgis/rest/services/Parcels_UT/MapServer", { id : 'parcels', visible : false }); parcelLayer.push({ layer : parcels, title : 'Parcels' }); //add parcel feature layer query info for popup window var content = "<b>Address</b>: ${ADDR}" + "<br /><b>Owner Name</b>: ${OWNER}" + "<br /><b>Parcel ID</b>: ${APN}" + "<br /><b>City</b>: ${CITY}" + "<br /><b>Acres</b>: ${TOTAL_ACRES}"+ " <br /><a href='${COUNTY_LINK}' target='_blank'>County Assessor Site</a>" var popUpTemplate = new esri.InfoTemplate("Parcel", content); //add parcel feature layer featureParcel = new esri.layers.FeatureLayer("http://2501s-jjohnson:6080/arcgis/rest/services/Parcels_UT/MapServer/0",{ mode: esri.layers.FeatureLayer.MODE_SELECTION, outFields: ["*"], infoTemplate:popUpTemplate }); //set selection Symbol var selectionSymbol = new esri.symbol.SimpleFillSymbol().setColor(new dojo.Color([255,255,0,0.5])); selectionSymbol.setOutline(new esri.symbol.SimpleLineSymbol("solid", new dojo.Color([255,0,0]), 2)); featureParcel.setSelectionSymbol(selectionSymbol); //create legend dojo.connect(app.map, 'onLayersAddResult', function(results) { var legend = new esri.dijit.Legend({ map : app.map, layerInfos : legendLayers }, "retail"); legend.startup(); }); //add all layers to map app.map.addLayers([parcels]); //add layer arrays into legend object legendLayers["parcel"] = parcelLayer; dojo.connect(app.map, 'onLayersAddResult', function(results) { //for each layer array in legend object for (var k in legendLayers){ //add legend check boxes for each layer //to toggle layer visibility dojo.forEach(legendLayers, function(layer) { var layerName = layer.title; var checkBox = new dijit.form.CheckBox({ name : "checkBox" + layer.layer.id, value : layer.layer.id, checked : layer.layer.visible, onChange : function(evt) { var clayer = app.map.getLayer(this.value); clayer.setVisibility(!clayer.visible); this.checked = clayer.visible; //toggle the feature layer parcel query //parcelClick indicates whether the parcel layer is on if (this.value ==="parcels" && this.checked === true){ clickConnect(true); parcelClick = true; } else if (this.value ==="parcels"){ clickConnect(false); parcelClick = false; } } }); //add the check box and label to the table of contnents dojo.place(checkBox.domNode, dojo.byId(k), "after"); var checkLabel = dojo.create('label', { 'for' : checkBox.name, innerHTML : layerName }, checkBox.domNode, "after"); dojo.place("<br />", checkLabel, "after"); }); } }); dojo.connect(app.map, "onLoad", initSelectToolbar); } function initSelectToolbar(map) { selectionToolbar = new esri.toolbars.Draw(map); var selectQuery = new esri.tasks.Query(); dojo.connect(selectionToolbar, "onDrawEnd", function(geometry) { selectionToolbar.deactivate(); selectQuery.geometry = geometry; var deferred = featureParcel.selectFeatures(selectQuery, esri.layers.FeatureLayer.SELECTION_NEW); app.map.infoWindow.setFeatures([deferred]); app.map.infoWindow.show(); }); } function pointToExtent(map, point, toleranceInPixel) { var pixelWidth = map.extent.getWidth() / map.width; var toleraceInMapCoords = toleranceInPixel * pixelWidth; return new esri.geometry.Extent( point.x - toleraceInMapCoords, point.y - toleraceInMapCoords, point.x + toleraceInMapCoords, point.y + toleraceInMapCoords, map.spatialReference ); } dojo.ready(init);
