How to retrieve featurelayer object from map object?

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<SPAN class="punctuation token">.</SPAN><SPAN class="token function">getLayer</SPAN><SPAN class="punctuation token">(</SPAN>map<SPAN class="punctuation token">.</SPAN>graphicsLayerIds<SPAN class="punctuation token">[</SPAN>x<SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

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