How to retrieve featurelayer object from map object?

[baohuachu3]

Some FeatureLayers are added to map. How to retrieve one feature layer from map object? I have tried

map.getLayer(map.layerIds[x]), the object is not FeatureLayer type object.

with the following

map.getLayer('MapServiceWeb_Operational_7147');

you are getting the map layer setting the layer id.

Baohoa,

   A FeatureLayer is always added to the map.graphicsLayerIds array and not the map.layerIds array. So the code would look like: 

map.getLayer(map.graphicsLayerIds[x]);‍

Or if you know the exact layer id the you can use the code Panagiotis provided.
