Please help me understand IdentifyTask with IdentifyParam

TyroneBiggums — Mon, 15 May 2017 16:57:40 GMT

I'm using the IdentifyTask that requires a URL of the service. I'm also using IdentifyParam that has an option to return the top layer. Does that mean that I can only return the top lay of the service in the URL? I'd like to be able to dynamically grab the top visible layer, period, regardless of the IdentifyTask URL. Is that possible?

I'm using 3.20.

Thanks

Tyrone,

Ye,s it will be just the top layer of the url. You would have to know the map service order in the map to manually decide if service a top layer should be returned or service b top layer based on how those services where added to your map object.
