Property Details

active Property active Boolean

Set this property to true to display a spinner icon. You should do this if the action executes an async operation, such as a query, that requires letting the end user know that a process is ongoing in the background. Set the property back to false to communicate to the user that the process has finished.

Default Value:false

className Property className String

This adds a CSS class to the ActionButton's node. It can be used in conjunction with its image property or by itself. Any icon font may be used in this property. The Esri Icon Font is automatically made available via the ArcGIS Maps SDK for JavaScript for you to use in styling custom actions. To use one of these provided icon fonts, you must prefix the class name with esri-. For example, the default zoom-to action in Popup uses the font esri-icon-zoom-in-magnifying-glass.
