Initialization

This article details the properties that are passed as parameters to the window.LearnosityAuthor.init() method to initialize Author API.

This method is the starting point to initializing and rendering Author API, and as you can see in the example below, takes three key parameters.

Initialization object
HTML element selector
Callbacks object

The Initialization object is mandatory. Further detail on getting started and initializing Author API can also be found in the Quick Start guide.

Example

var authorApp = LearnosityAuthor.init(initializationObject, callbacks);

Initialization

The Initialization object is a JSON object which is passed as the first parameter into the window.LearnosityAuthor.init() method. It includes all the information needed to initialize the API.

It contains the following two top-level properties:

Security object
Request object

Security Object

The security object handles authentication and security in communication with the API.

The signature is the result of applying a SHA-256 hash algorithm on the attributes of the security object and string representation of the request object.

A guide on how to accomplish this can be found on our Security & Authentication page, as well as in the source for our demos site

Request Object

The request object contains all of configuration properties of authoring items and activities as well as user identification

configactivity_edititem_searchfilter

object

Options for filtering and restricting content that is displayed on the Item lookup screens

Properties:
restricted	Type: object Holds config for filters which are applied by default to the search criteria for the Item lookup results. Use this to restrict what items users can see, as these cannot be changed by the user.

configactivity_edititem_searchfilterrestricted

object

Holds config for filters which are applied by default to the search criteria for the Item lookup results. Use this to restrict what items users can see, as these cannot be changed by the user.

Properties:
created_by	Type: array Only display Items created by the users in the passed array of strings (based on their `user.id`). A maximum of 50 string values are allowed. Default: `[]`
current_user	Type: boolean Only display Items created by the current user (based on their `user.id`), if `created_by` is present, this option overrides `created_by`. Default: `false`
tags	Type: object Holds config for tag filters which are applied by default to the search criteria for the Item lookup results.

configactivity_edititem_searchfilterrestrictedtags

object

Holds config for tag filters which are applied by default to the search criteria for the Item lookup results.

Properties:
all	Type: array Each entry in the `tags.all` array is an object. This object can follow three formats, the first being the TagsV2 object format where it only has the `type` and `name` properties. It can also follow a variation of the said format where the `name` attribute is instead an array of strings which makes it more convenient to specify multiple tags of the same type. For these two formats, Items must have all the specified tags to be visible. The last format is another variation of the first one where the `name` property is omitted leaving the object with just the `type` property. In this case, Items must have at least one tag of the given type to be visible. If there is more than one entry in `tags.all`, Items are only displayed if they have all of the tags specified for each entry in this initialization option. See knowledge base article on advanced tag search for more information.
either	Type: array Each entry in the `tags.either` array is an object. This object can follow the TagsV2 object format where it only has the `type` and `name` properties. It can also follow a variation of the said format where the `name` property is instead an array of strings which makes it more convenient to specify multiple tags of the same type. Items are only displayed if they have at least one of the tags specified for at least one entry in this initialization option. Note `tags.either` only supports an array of `TagsV2` objects, not arrays of `TagsV2` objects. See knowledge base article on advanced tag search for more information.
none	Type: array Each entry in the `tags.none` array is an object. This object can follow the TagsV2 object format where it only has the `type` and `name` properties. It can also follow a variation of the said format where the `name` property is instead an array of strings which makes it more convenient to specify multiple tags of the same type. Items are only displayed if they don't have each tag specified for each entry in this initialization option. Note For performance reasons, this initialization option will only work if tags.all or tags.either are set as well. If that's not the case, tags.none will be ignored. See knowledge base article on advanced tag search for more information.

object

Holds configuration for the Author API container.

Properties:
fixed_footer_height	Type: integer If the height of the container is left as 'auto' and scrolling is enabled then preview mode will accommodate all the space to the bottom of a viewport. There are cases though, when a host page may use a footer with position set to fixed. Such footer will cover bottom part of the preview mode making it inaccessible. Specifying a height of the footer will let a preview mode to adjust its height accordingly. This is the height from the bottom edge of div.lrn-author-item-content to the bottom edge of the bottom element (footer) in the page. Integer value corresponds to pixels. Default: `0`
height	Type: integer The height of Author API app is automatic, which means the more content is there, the more it grows. Except in a preview mode where scrolling is enabled, the height of the container of Author API will be adjusted and will fit exactly within specified height to expose how scrolling functionality works. It's in particular very useful when loading Author API in fixed size modal window. Setting this sets the height of the Author API container in Item edit/preview mode when "Enable scrolling for long content" is ticked in the Item settings view only. Integer value corresponds to pixels. Default: `auto`
scroll_into_view_selector	Type: string When navigating between views (e.g. from Item edit to Question edit view), Author API scrolls its main container into view by default. If you want Author API to scroll another container into view, you can define that container's selector (as a jQuery selector) here. In Author Site, this is set to 'body' so that Author API is not partially hidden by Author Site's navigation bar. This only affects the following transitions: Clicking an item from the item list Adding a new widget to an item Edit an existing widget in an item Selecting a widget from the tile view Author API will scroll into the selector only if the top edge of its container is not visible in the viewport. This is not yet supported in Activity Builder.

allow_filtered_tags_overwrite	Type: boolean If set to true, then a user can save Items which do not have the tags required by the tag filters below. Default: `false`
all	Type: array Each entry in the `tags.all` array is an object. This object can follow three formats, the first being the TagsV2 object format where it only has the `type` and `name` properties. It can also follow a variation of the said format where the `name` attribute is instead an array of strings which makes it more convenient to specify multiple tags of the same type. For these two formats, Items must have all the specified tags to be visible. The last format is another variation of the first one where the `name` property is omitted leaving the object with just the `type` property. In this case, Items must have at least one tag of the given type to be visible. If there is more than one entry in `tags.all`, Items are only displayed if they have all of the tags specified for each entry in this initialization option.

Note `tags.either` only supports an array of `TagsV2` objects, not arrays of `TagsV2` objects. See knowledge base article on advanced tag search for more information.
none	Type: array Each entry in the `tags.none` array is an object. This object can follow the TagsV2 object format where it only has the `type` and `name` properties. It can also follow a variation of the said format where the `name` property is instead an array of strings which makes it more convenient to specify multiple tags of the same type. Items are only displayed if they don't have each tag specified for each entry in this initialization option. Note For performance reasons, this initialization option will only work if tags.all or tags.either are set as well. If that's not the case, tags.none will be ignored. See knowledge base article on advanced tag search for more information.

mode

string

The mode of component to be loaded. This attribute is required. Currently we support:

"item_edit"
"item_list"
"activity_edit"
"activity_list"

In item_edit mode, users cannot navigate to the Item list. Thus, this mode is useful for integrating a custom CMS instead of using Learnosity's.

reference

string | boolean

Applies in item_edit and activity_edit modes only, denotes the reference of the Item or Activity you are creating/editing. If the Item or Activity already exists, it will be loaded from the Item bank. Otherwise, a new item/activity will be created with the provided reference, and will be stored in the Item bank once saved.

If using Author API v1.20.0 or later, do not encode the reference by calling encodeURIComponent or any other encoding method since Author API already encodes it.

Keep track of your Item references and Activity references in your CMS, or use the list view (item_list and activity_list modes) for easier management of Items and Activities.

For item_edit mode, you can also pass false (Boolean), will simply initialize Author API without fetching and loading an Item or creating a new Item. The UI will be empty, and a reference can be set later.

The second parameter passed to window.LearnosityAuthor.init() is a string, containing a full CSS selector to an element on the HTML page. Each example below could be a valid value:

#learnosity_author // CSS selector based on id of an element
.learnosity_author // CSS selector based on a class of an element

This value tells Author API where to render itself on the page.

Note If the HTML element selector is not provided, Author API will attempt to look for the element with a id "learnosity-author".

Note See the quick start guide for more information on how to build an example HTML page.

customButtons

array

Use customButtons for custom behaviour, e.g. adding an embedded video into a field. If customButtons are defined, Question Editor API will display a custom button in its toolbar. When the button is clicked by an author, the function is called.

Properties:
name	Type: string A unique identifier for the button.
icon	Type: string A link to the button icon (Recommended dimensions: 25px by 25px).
label	Type: string The buttons label.
func(attribute, callback)	Type: callback() The callback function which is executed when the custom button is clicked.
attributes	Type: array A string array containing the path selectors of the rich text editors with which the custom buttons are to be associated with. If this is undefined (or empty), the buttons will be associated with all rich text editor instances. For array type fields like options, you can either define a selector for a specific entry, e.g. `options[0]`, or you can specify a selector targeting the whole array, e.g. `options[*]`. For more on rich text editor selectors see the editor layout components section.
