No, Dijit does not provide pre-configured dialogs, like alert, confirm, or prompt.

Why? As simple as these may seem on the surface, each organization or application often needs something subtly different in terms of layout, appearance, behavior, events, and internationalization. Dojo and Dijit provide all the elements you need to make a variety of dialogs, including dijit/Dialog, dijit/form/Button, dojo/on, dojo/Deferred and dojo/i18n.

The time spent creating a dialog that suits your needs perfectly will be small compared to the overall time spent developing an application, and you will have a reusable module tailored to your specific needs that you can use throughout your application, or even across applications throughout your organization. Creating a custom dialog also ensures that teams of developers don’t have to struggle to get a generic confirmation dialog to respond and look like other dialogs in the application.
