Index of ServiceLayers in a Map

[UrsRichard]

Hi there,

I have a map with serveral different MapServiceLayers (DynamicMapServiceLayers and FeatureLayer). Now I'm looking for indexes of each of this services in the map. So I like to know which is the topmost, the second topmost etc..

With the information about the indexes I can as as example the map.reorderLayer(layer, index) function for reordering.

best regards

Urs

You can use LayerInfo object to get the sub layer IDs.

This documentation talks about LayerID proprty of the feature layer

Hope this helps.

All layers has a id property. Even though it is a string type. you could name the layers '0', '1', '2'.... Since javascript is loosely typed, those ids can be easily treated as number with min code.
