How to know type of a layer?

Pankajroy — Thu, 12 Sep 2013 11:00:17 GMT

Hi All,

Using java script API I need to iterate through the layers of map and depending on the type of layer, need to perform certain actions.
Can anyone tell me how to know the type of layer, whether it is a tiled, dynamic, WMS etc.

Thaks in advance

Try:

switch(layer.declaredClass) {
 case "esri.layers.ArcGISDynamicMapServiceLayer":
 case "esri.layers.ArcGISImageServiceLayer":
 case "esri.layers.WebTiledLayer":
...
}

Hi, each layer (actually most esri classes do) should have a "declaredClass" property.
So you can try call:

layer.declaredClass

to see the type of the layer.

the returned value would be like:

"esri.layers.ArcGISDynamicMapServiceLayer",
"esri.layers.WebTiledLayer",
...
