--- Added: v2.0.0 Status: Active --- # Content Action component Adds options to a Document List actions menu for a particular content type. ![Document Actions](docassets/images/document-actions.png) ## Contents - [Basic Usage](#basic-usage) - [Properties](#properties) - [Events](#events) - [Details](#details) - [Built-in action examples](#built-in-action-examples) - [Error, Permission and Success callbacks](#error-permission-and-success-callbacks) - [Customizing built-in actions](#customizing-built-in-actions) - [See also](#see-also) ## Basic Usage ```html ... ``` ```ts export class MyView { // ... myCustomAction1(event) { let entry = event.value.entry; alert(`Custom document action for ${entry.name}`); } myCustomActionAfterDelete(event) { let entry = event.value.entry; alert(`Custom callback after delete system action for ${entry.name}`); } } ``` ### Properties | Name | Type | Default value | Description | | ---- | ---- | ------------- | ----------- | | title | `string` | `'Action'` | The title of the action as shown in the menu. | | icon | `string` | | The name of the icon to display next to the menu command (can be left blank). | | handler | `string` | | System actions. Can be "delete", "download", "copy" or "move". | | target | `string` | [ContentActionTarget.All](https://github.com/Alfresco/alfresco-ng2-components/blob/development/lib/content-services/document-list/models/content-action.model.ts) | Type of item that the action applies to. Can be one of the values provided by the enum : **All**, **Folder**, **Document** | | permission | `string` | | The permission type. | | disableWithNoPermission | `boolean` | | Should this action be disabled in the menu if the user doesn't have permission for it? | | disabled | `boolean` | `false` | Is the menu item disabled? | ### Events | Name | Type | Description | | ---- | ---- | ----------- | | execute | `EventEmitter<{}>` | Emitted when the user selects the action from the menu. | | permissionEvent | `EventEmitter<{}>` | Emitted when a permission error occurs | | error | `EventEmitter<{}>` | Emitted when an error occurs during the action. Applies to copy and move actions. | | success | `EventEmitter<{}>` | Emitted when the action succeeds with the success string message. Applies to copy, move and delete actions. | ## Details The document actions are rendered on a dropdown menu for each items of content. You can use the `target` property to choose whether the action applies to folders or documents. A number of built-in actions are defined to handle common use cases: - **Download** (document) - **Copy** (document, folder) - **Move** (document, folder) - **Delete** (document, folder) You can use one of the built-in handlers by assigning its name to the `handler` property. (The names are case-insensitive, so `handler="download"` and `handler="DOWNLOAD"` will trigger the same action.) You can also add your own handler by implementing the `execute` event. Note that you can use _both_ a built-in handler and your own `execute` function in the same action. The `execute` function is passed a `NodeMinimalEntry` as its parameter (see the [Document Library model](document-library.model.md) page for more information) which contains full details of the item that the action is operating on. For example, with `handler="delete"` you could use `execute` to show a message with the name, type and other details of the item just deleted: ```html ``` ```ts myCustomActionAfterDelete(event) { let entry = event.value.entry; let item = ""; if (entry.isFile) { item = "file"; } else if (entry.isFolder) { item = "folder" } this.notificationService.openSnackMessage(`Deleted ${item} "${entry.name}" `, 20000); } ``` ![Custom delete message screenshot](docassets/images/ContentActSnackMessage.png) ### Built-in action examples #### Delete - System handler combined with custom handler If you specify both `handler="delete"` and your own custom handler with `(execute)="myCustomActionAfterDelete($event)"`, your handler will run after a delete completes successfully. A delete operation is considered successful if there are no permission or network-related errors for the delete request. You can avoid permission errors simply by disabling an item for users who don't have permission to use it (set `disableWithNoPermission="true"`). ```html ``` ![Delete disable action button](docassets/images/content-action-disable-delete-button.png) You can also implement the `permissionEvent` to handle permission errors (to show the user a notification, for example). Subscribe to this event from your component and use the [Notification service](notification.service.md) to show a message. ```html ``` ```ts export class MyComponent { onPermissionsFailed(event: any) { this.notificationService.openSnackMessage(`you don't have the ${event.permission} permission to ${event.action} the ${event.type} `, 4000); } } ``` ![Delete show notification message](docassets/images/content-action-notification-message.png) #### Download This action simply starts a download of the corresponding document file. ```html ``` ![Download document action](docassets/images/document-action-download.png) #### Copy and move These actions show the destination chooser dialog for copy and move actions. By default, the destination chooser lists all the folders of the subject item's parent. However, it won't allow the item being copied/moved to be the destination if it is itself a folder. ![Copy/move dialog](docassets/images/document-action-copymovedialog.png) ```html ``` ### Error, Permission and Success callbacks Defining error, permission and success callbacks are pretty much the same as doing it for the delete permission handling. - The error handler callback gets the error object which was raised - The success callback's only parameter is the translatable success message string (could be used for showing in snackbar for example) - The permissionEvent callback is the same as described above with the delete action ![Copy/move document action](docassets/images/document-action-copymove.png) ### Customizing built-in actions The built-in actions are defined in the [Document Actions service](document-actions.service.md) and [Folder Actions service](folder-actions.service.md) but you can register new actions with these services and override the default implementations. See the doc pages for [Document Actions service](document-actions.service.md) and [Folder Actions service](folder-actions.service.md) for details and examples. ## See also - [Document list component](document-list.component.md) - [Document actions service](document-actions.service.md) - [Folder actions service](folder-actions.service.md)
