onClick on ArcGISDynamicMapServiceLayer

christianromero

Hi, I'm trying to replicate this Onclick event for a sublayer in a ArcGISDynamicMapServiceLayer  sample but i hadn't success.

Mine scenario are: I've a menu each action can show a different view of data (layers) one of those are a time TimeSlider, the time slider works fine but a need to add a function for display some data after doing a click on certain point on the map.

function inittimeSlider() {

    try{

        var opLayer = new esri.layers.ArcGISDynamicMapServiceLayer(document.getElementById('hUrl').value);

        opLayer.setVisibleLayers([CapaPosicion.FALLAS.value]);

        opLayer.id = 'timeSlider';

        opLayer.opacity = 0.6;              

       

        var component = dijit.registry.byId("timeSliderDiv");      

            if (component) {

                //destroy it

                dojo.domConstruct.destroy(component);

                dijit.registry.remove(timeSlider)

                timeSlider.destroy()

            }             

            timeSlider = new esri.dijit.TimeSlider({

                style: "width: 100%;"

            }, dojo.dom.byId("timeSliderDiv"));

            map.setTimeSlider(timeSlider);

            var timeExtent = new esri.TimeExtent();

            timeExtent.startTime = new Date("01/01/2015 UTC");

            timeExtent.endTime = new Date("08/31/2015 UTC");

            timeSlider.setThumbCount(2);

            timeSlider.createTimeStopsByTimeInterval(timeExtent, 1, "esriTimeUnitsMonths");

            timeSlider.setThumbIndexes([0, 1]);

            timeSlider.setThumbMovingRate(2000);

            timeSlider.startup();

            //add labels for every other time stop

            var labels = dojo._base.array.map(timeSlider.timeStops, function (timeStop, i) {

                //if ( i % 2 === 0 ) {

                return timeStop.getUTCFullYear();

                //} else {

                return "";

                //}

            });

            timeSlider.setLabels(labels);

            timeSlider.on("time-extent-change", function (evt) {

                var startValString = Meses(evt.startTime.getUTCMonth());

                var endValString = Meses(evt.endTime.getUTCMonth());

                dojo.dom.byId("daterange").innerHTML = "<i>" + startValString + " a " + endValString +  "  " + "<\/i>";

            });

         

            map.addLayers([opLayer]);

            map.on("load", initFunctionality);

            function initFunctionality() {

                map.on("click", doIdentify);

               var identifyTask = new esri.tasks.IdentifyTask(document.getElementById('hUrl').value);

                var identifyParams = new esri.tasks.IdentifyParameters();

                identifyParams.tolerance = 3;

                identifyParams.returnGeometry = true;

                identifyParams.layerIds = [CapaPosicion.FALLAS.value];

                identifyParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_ALL;

                dojo.on(identifyTask, "complete", function (event) {

                    array.forEach(event.results, function (feature) {                     

                        if (feature.layerName == "timeSlider") {

                            alert('123456789');

                        }

                    });

                });

            }

            function doIdentify(event) {

                map.graphics.clear();

                identifyParams.geometry = event.mapPoint;

                identifyParams.mapExtent = map.extent;

                identifyTask.execute(identifyParams)

            }  

    }

        catch (e) {

            console.log("Error : " + e);

            HideProgress();

    }

}

at first I thought it was the same way to what is done in the onclick of esri.layers.FeatureLayer,

exist another way ? or I have something wrong that can not see ?

Christian,

   It is likely that map is already loaded before you get to running this portion of code. Seems like you need to be listening for the "layer-add" event and check if the layer added is your opLayer and if so execute you initFunctionality function.
