    • Returns boolean - True if the action is available, false otherwise
  • getHandler(key: string): ContentActionHandler
    Gets the handler function for an action.
  • setHandler(key: string, handler: ContentActionHandler): boolean
    Sets a new handler function for an action.
    • key: string - Identifier for the action
    • handler: ContentActionHandler - The new handler function
    • Returns boolean - True if the key was a valid action identifier, false otherwise

Details

This service implements the built-in actions that can be applied to a folder shown in a Document List component: delete, download, copy and move (see the Content Action component for further details and examples of these menu items). However, you can also use the service to add extra actions or replace the built-in ones with your own implementation.

Registering an action

In the example below, a custom handler called my-handler is registered with the service. This action will invoke the myFolderActionHandler function each time it is selected from the Document List menu.

import { FolderActionsService } from '@alfresco/adf-content-services';

export class MyView {

    constructor(folderActions: FolderActionsService) {
        folderActions.setHandler(
            'my-handler',
            this.myFolderActionHandler.bind(this)
        );
    }

    myFolderActionHandler(obj: any) {
        window.alert('my custom action handler');
    }
}

The action can then be used from the component in the usual way:

<adf-document-list ...>
    <content-actions>

        <content-action
            target="folder"
            title="My action"
            handler="my-handler">
        </content-action>

    </content-actions>
</adf-document-list>

You can also override a built-in handler (eg, 'download') with your own function:

export class MyView {

    constructor(folderActions: FolderActionsService) {
        folderActions.setHandler(
            'download',
            this.customDownloadBehavior.bind(this)
        );
    }

    customDownloadBehavior(obj: any) {
        window.alert('my custom download behavior');
    }
}

You will probably want to set up all your custom actions at the application root level or with a custom application service.
