Description
This sample shows how to display the results of an identify task in a Popup. The Popup class, introduced at version 2.3 of the ArcGIS API for JavaScript, is a custom info window that provides additional capabilities to the standard info window. The additional functionality includes the ability to navigate through a set of selected features. The ability to navigate through the selected set of features helps streamline the process of displaying identify results. Rather than displaying the results from multiple features in separate tabs or as a complex tree-view structure users can simply navigate forward and backward through the identify results.Code
