FeatureLayer & ArcGISDynamicMapServiceLayer

[GyeyoungChoi]

Hello,

I was making a map with popup function however I'm stuck or have no idea using

        var featureLayer = new esri.layers.FeatureLayer("http://localhost/ArcGIS/rest/services/TAVP/MapServer",{
   opacity:0.5,
   mode: esri.layers.FeatureLayer.MODE_SELECTION,
   outFields: ["*"],
   infoTemplate:template
   });

it works when I change new esri.layers.FeatureLayer to new esri.layers.ArcGISDynamicMapServiceLayer

but then popup will not work.


Can anyone help me out with this?


URL working fine and map as well

hi jack,

a feature layer needs to have the index of a layer in a map service specified.  check out the following article for more information.

ie. the following is a valid FeatureLayer...

http://services.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_1990-2000_Population_Change/M...

while the url below is a reference to the map service itself (and would be a valid ArcGISDynamicMapServiceLayer

http://services.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_1990-2000_Population_Change/M...

check out each link in the browser to see the Rest endpoint for each resource to compare and contrast what is returned.
