displaying scale of dyamic map service layer

[Egan_LouisFajardo]

I would like to know and display the scale of a dynamic service layer by using the onExtentChange event, but the LOD argument is only valid for tile map services. Is there an equivalent way for dynamic map services?

The scale property applies to the map, not the individual layer, so you canuse map.getScale() to display it.

You can get the map's level using map.getLevel(), but as you identified this only applies if there is a tiled layer in the map.
