ArcGIS-JSAPI: Clicking on a webmap without clicking on a webmap

Clicking on a map without clicking on a map

An ArcGIS JavaScript API hack

Purpose: I have a map application with a list of results from a query. When I click on one of the items in the result list, I wanted the map to zoom to the associated feature, and trigger a click that shows the result in a popup.

Library: ArcGIS JavaScript API

Version: tested on versions 3.9-3.13.
