$modal is a service to quickly create AngularJS-powered modal windows. Creating custom modals is straightforward: create a partial view, its controller and reference them when using the service.

The $modal service has only one method: open(options) where available options are like follows:

• templateUrl - a path to a template representing modal's content
• template - inline template representing the modal's content
• scope - a scope instance to be used for the modal's content (actually the $modal service is going to create a child scope of a provided scope). Defaults to $rootScope
• controller - a controller for a modal instance - it can initialize scope used by modal. A controller can be injected with $modalInstance
• resolve - members that will be resolved and passed to the controller as locals; it is equivalent of the resolve property for AngularJS routes
• backdrop - controls presence of a backdrop. Allowed values: true (default), false (no backdrop), 'static' - backdrop is present but modal window is not closed when clicking outside of the modal window.
• keyboard - indicates whether the dialog should be closable by hitting the ESC key, defaults to true
• windowClass - additional CSS class(es) to be added to a modal window template

The open method returns a modal instance, an object with the following properties:

• close(result) - a method that can be used to close a modal, passing a result
• dismiss(reason) - a method that can be used to dismiss a modal, passing a reason
• result - a promise that is resolved when a modal is closed and rejected when a modal is dismissed
• opened - a promise that is resolved when a modal gets opened after downloading content's template and resolving all variables

In addition the scope associated with modal's content is augmented with 2 methods:

• $close(result)
• $dismiss(reason) Those methods make it easy to close a modal window without a need to create a dedicated controller
