Web map by ID

Description

This sample displays a map generated using the ArcGIS.com map viewer. The map's author used the tools in the map viewer to select a basemap, add operational layers, define an initial extent and create popup windows.

The ArcGIS API for JavaScript has a utility method that allow you to use maps from ArcGIS.com or your own Portal in a JavaScript application: esri/arcgis/utils.createMap, which is used in this sample. In addition, you can also specify a portal URL, via thearcgisUrlproperty,besides the default ArcGIS Online URL ofhttp://www.arcgis.com/sharing/rest/content/items.
