How to get feature layer name, once graphic (feature) is clicked

tonylife

When click a feature on map, the popup shows the attributes of the feature.
I want to show feature layer name in content of popup using infoTemplate.
I am able to get the graphic information at the time.
Is there a way I can get the feature layer name also?

Thanks,
Tony

One option is to define a function that will generate your popup content using setContent. Then you can use the graphic.getLayer method to retrieve the graphics layer name. Here's an example that shows how this works:

it wouldn't be impossible to accomplish this, but the graphic returned by the GraphicsLayer onClick event does not expose the corresponding featureLayer name.

perhaps this?

var template = new esri.InfoTemplate();

var featureLayer = new esri.layers.FeatureLayer("http://servicesbeta.esri.com/ArcGIS/rest/services/SanFrancisco/SFStreetTreesRendered/MapServer/0",{
          id: "My Feature Layer Name",
    mode: esri.layers.FeatureLayer.MODE_SELECTION,
          outFields: ["*"],
          infoTemplate:template
});
//first pass infoTemplate, then instantiate feature layer, then set title using id
template.setTitle(featureLayer.id);

Here's the way I got the layer name into my infoWindow. This shows all the visible attributes for the layer

        connect.connect(map, "onClick", executeIdentifyTask);
        identifyTask = new esri.tasks.IdentifyTask(parameters.url);
        identifyParams = new esri.tasks.IdentifyParameters();
        identifyParams.tolerance = 3;
        identifyParams.returnGeometry = true;
        //identifyParams.layerIds = [0, 117];
        identifyParams.layerIds = myLayer.visibleLayers;
        identifyParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_ALL;
        identifyParams.width = map.width;
        identifyParams.height = map.height;

        map.infoWindow.resize(415, 200);
        map.infoWindow.setTitle("Results");

    function executeIdentifyTask(evt) {
        identifyParams.geometry = evt.mapPoint;
        identifyParams.mapExtent = map.extent;
        identifyParams.layerIds = myLayer.visibleLayers; //in case the visible layers have changed for the layer

        var deferred = identifyTask.execute(identifyParams);
        deferred.addCallback(function (response) {
            return dojo.map(response, function (result) {
                var feature = result.feature;
                var infoTemplate = new esri.InfoTemplate("test", "${*}");
                var contentString = "";
                var sp = new Array();
                var sp = feature.attributes;

                contentString += "<b>" + result.layerName + "</b><hr width = '90%'>";

                for (x in sp) {
                    contentString += x + ": " + feature.attributes + "<br/>";
                }
                var infoTemplate = new esri.InfoTemplate();
                var titleText = "<div>" + "Title" + "</div>"
                infoTemplate.setTitle(titleText);
                infoTemplate.setContent(contentString);
                feature.setInfoTemplate(infoTemplate);

                return feature;
            });
        });
        map.infoWindow.setFeatures([deferred]);
        map.infoWindow.show(evt.mapPoint);
    }

Thank you!
This is the solution I am using. I do use a customized function with graphic parameter in setContent.
Actually what I need is graphic.getLayer().name.
