Change Dynamic layer visibility

Question

hi,

Suppose I have a dynamic map service with multiple layers, is there a way to control which layer to show/hide from javascript api? For example,

var dLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://localhost:6080/arcgis/rest/services/map1/MapServer");

And MapServer dLayer has 3 layers:
Layers:* School (0)
* CityHall (1)
* River (2)

And I want the web client to control which layer to show. Is this possible with javascript API?
