How to retrieve map data from sublayer using ARCGIS JavaScript tileLayer

[AbramhumHsu]

I meet a problem about how to retrieve map data from sublayer using ARCGIS JavaScript tileLayer. The example mapserver is like following:
https://arcgis.tpgos.gov.taipei/arcgis/rest/services/TAIPEI_MAP/LAYER_NWPIPE_TILE/MapServer

It has layers, so if I hope to get id:1 via the using of tileLayer in ARCGIS JavaScript,
How to make that, thanks a lot.

Hi @AbramhumHsu, the TileLayer is intended to use with a MapServer, and Sublayers are not intended to be handled individually, with the exception of their: title, popup, and legend.
