Accessing featurelayer properties from an array of feature layers javascript api

DanRicketts

I am adding my feature layers to an array and map as follows:

         dojo.forEach(globals.layers, function (addit, i) {

                globals.featureLayers = new FeatureLayer(addit.url, {

                    mode: addit.mode,

                    id: addit.id,                  

                    outFields: addit.outFields,

                    infoTemplate: addit.infoTemplate

                });

                if (addit.type == "poly") {

                    globals.featureLayers.setRenderer(renderer)

                }

                map.addLayer(globals.featureLayers);

            });

This works fine and the layers needed display in the browser.  However, when I try to access the graphics array within the feature layer by doing the below in the above forEach statement:

               var graphicstmp = globals.featureLayers.graphics;

                console.log("Features Layer Properties in base ", graphicstmp)

I get an empty array in graphicstmp.  If I look at the globals.featureLayers array in dev tools I see the graphics object there and it is not empty.  It has the properties for the layer that are displaying.  So apparently I am doing something wrong with trying to access it this way globals.featureLayers.graphics.  Help is appreciated.  I eventually want to modify some of the properties but I first need to be able to access them.

I think Sarah Clark​ is correct that you are probably attempting to access the graphics before they have been loaded. However, I would use the update-end event instead of the load event. The load event fires when the layer properties are populated, the update-end event should fire when all graphics have finished loading.

load event:

Fires after layer properties for the layer are successfully populated.

update-end event:

Fired when the layer has finished updating its content.

if you are only interested in listening to this event the first time the feature layer loads look into on.once().
