Legend - toggle services

ArowanaIndah — Tue, 03 Jun 2014 06:10:38 GMT

Hi,
I'm using 'Display identify results in popup' sample and try to display the legend like 'Legend - toggle services' sample. I try to mix the code together and it seem not working. I'm not very good in coding.

Thank

Hi Arowana,

Looks like you are calling the event 'layers-add-result', so you will need to use map.addLayers method rather than map.addLayer. Try the following:

Legend - toggle services and multiple ArcGISDynamicMapServiceLayer

ArowanaIndah — Fri, 10 Dec 2021 21:11:02 GMT

Hi Jake,
Thank for the answer. Sorry for asking again. If i want to use multiple ArcGISDynamicMapServiceLayer, from a code above how do i configure IdentifyTask code.

Thank

        map.on("load", mapReady);

        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);
        }
