Methods

This article details methods the client can use to interact with Author API.

The following methods are accessed via the window.LearnosityAuthor object.

When the <script src="https://authorapi.learnosity.com?v1"></script> tag is included on the page, the window.LearnosityAuthor object is instantiated, and ready for use.

Initialises the Author API and injects the authoring UI into a container element of the DOM.

Returns authorApp (object), representing the Author API instance and it's callable methods. All other public methods should be called against the instantiated Author app (see example below).

Parameters
initOptions
Type: object
Configures the Author API's behaviour.

See Initialization for more information.

eventOptions
Type: object
Attaches a readyListener and/or errorListener.

See Events for more information.

elementId
Type: string
This should match the id of a DOM container element (e.g. a div) into which the authoring UI should be injected. By default, the authoring UI will be injected into a container with id="learnosity-author".
Returns: AuthorApp
var initOptions = {
    /*
    See the Initialisation Options section
    for guidance on the initOptions object.
    */
};
// Instantiate the AuthorApp. The authoring UI
// will be injected into a container with id="learnosity-author".
var authorApp = LearnosityAuthor.init(initOptions, {
    readyListener: function () {
        bindEvents(); // Custom method
        createItem();
    }
});
// Alternatively, instantiate AuthorApp and inject
// into a container with id="my-custom-container".
var authorApp = LearnosityAuthor.init(initOptions, "my-custom-container"});

The following methods are accessed via the authorApp instance returned by window.LearnosityAuthor.init().

Changes the mode being used in Activity edit view.

Returns true (boolean) if successful, or false (boolean) if unable to change the Activity mode (e.g. when not on Activity edit view, the passed mode is not valid or is the same as the current mode).

Parameters
mode
Type: string

If no value is passed, the mode will simply be toggled from edit to preview and vice-versa.

Possible values:
  • edit
  • preview
Returns: boolean 
var result = authorApp.changeActivityMode('preview');
result = authorApp.changeActivityMode(); // toggle Activity view mode

Changes the mode being used in Item edit view.

Returns mode (string), the new Item mode, if successful, or false (boolean) if unable to change the Item mode (e.g. when not on Item edit view or Item settings view, the passed mode is not valid or is the same as the current mode).

Parameters
mode
Type: string

If no value is passed, the mode will simply be toggled from edit to preview and vice-versa.

Possible values:
  • edit
  • preview
Returns: boolean | string 
authorApp.changeItemMode('preview');

This method allows you to deselect all the previously selected Items.

Returns: boolean 
authorApp.clearSelectedItems();
Closes the Item settings view if it's open and returns true, else returns false.

Returns: boolean 
authorApp.closeItemSettings();

Creates a new Activity with the specified reference.

Parameters
activityReference
Type: string

Maximum length is 150 characters. It must not match the reference of an existing Activity in the Item bank (case-insensitive); otherwise, the operation will fail with an error. If no value is passed, the new Activity that will be created will have a UUID as the reference.

 
authorApp.createActivity();

Creates a new Item with the specified reference.

Parameters
itemReference
Type: string

Maximum length is 150 characters. It must not match the reference of an existing Item in the Item bank (case-insensitive); otherwise, the operation will fail with an error. If no value is passed, the new Item that will be created will have a UUID as the reference.

 
authorApp.createItem();

Destroys the current instance of the Author app. This will also restore the HTML hook used to first initialize the app. Remember to delete any reference to the instance.

authorApp.destroy();

Duplicates the Activity currently being edited or takes the author to the confirmation screen if duplicateActivitySettings.showConfirmationScreen is set to true.

Returns true (boolean) if it's possible to attempt duplication, or false (boolean) if unable to attempt duplication (e.g. when not editing an Activity, the passed duplicateActivitySettings.reference is not valid, Activity is empty).

Note This method may throw an error later despite returning true (boolean) if something goes wrong, for example, if the passed duplicateActivitySettings.reference is used by an existing Activity in the Item bank or the Activity that will be duplicated has missing Items.

Parameters
duplicateActivitySettings

Object containing the arguments for Activity duplication.
Returns: boolean 
authorApp.duplicateActivity({
    reference: 'NewReference',
    deepCopy: true,
    duplicateSharedPassages: true
});

Duplicates the current Item being edited. The duplicate Item will use the specified reference as its reference. All widgets in the Item are fully cloned with new internal UUID references except for shared passages because they are copied by reference. Any future changes to a shared passage will thus be applied to all of its copies. If the operation is successful, the duplicate Item is automatically loaded and saved.

Note The duplicate Item is not persisted in the Item bank if config.item_edit.item.save.persist option is false. Item duplication using this method is not supported when editing an Item within an Activity.

Returns true (boolean) if it's possible to attempt duplication, or false (boolean) if unable to attempt duplication (e.g. when not editing an Item, the passed reference is not valid, Item is empty).

Note This method may throw an error later despite returning true (boolean) if something goes wrong, for example, if the passed reference is used by an existing Item in the Item bank.

Alternatively, this method can be called by passing in duplicateItemSettings. This is only available on version 2019.2.LTS onwards.

Parameters
reference
Type: string

Maximum length is 150 characters. It must not match the reference of an existing Item in the Item bank (case-insensitive); otherwise, the operation will fail with an error. If an empty string or no value is passed, the duplicate Item that will be created will have a UUID as the reference.
duplicatePassages
Type: boolean

If set to to true, passages are duplicated among Items. If set to false, passages are shared.

Default: false
Returns: boolean 
authorApp.duplicateItem('', true); // Duplicate Item with random reference and duplicated passages

Loads an existing Activity with the specified reference. The said Activity must be owned by the consumer in the security parameters passed to the init method.

Parameters
activityReference
Type: string

Maximum length is 150 characters. It must match the reference of an existing Activity in the Item bank (case-sensitive); otherwise the operation will fail with an error.

 
authorApp.editActivity('authorapi-activity-demo');

Loads an existing Item with the specified reference. The said Item must be owned by the consumer in the security parameters passed to the init method.

Parameters
itemReference
Type: string

Maximum length is 150 characters.
create
Type: boolean

This controls what happens when the passed itemReference does not match the reference of an existing Item in the Item bank (case-sensitive). If true, a new Item will be created with the passed itemReference as its reference. If false or no value is passed, the operation will fail with an error.

This argument is not supported in the Activity edit view.

Gets the current Questions API instance which exposes a set of Questions API public methods for use. Properties of the Questions app include all Questions API methods except the init method

Returns questionsApp (object), the current Questions API instance, or false (boolean) if not editing an Item.

Note New Questions API instances are created throughout the lifetime of an Author app (e.g. whenever an Item is rendered) so it is best to hook into the Author API's render:item event to get the current Questions API instance.

Returns: questionsApp | boolean 
authorApp.questionsApp();

Checks if the current Item or Activity being edited is clean (i.e. no unsaved changes) and thus safe to be unloaded.

Parameters
isSafe
Type: boolean
If true, the Item or Activity is marked clean regardless of whether it has unsaved changes or not. This is necessary if saving Items is done externally. If false or no value is passed, the Item or Activity is marked dirty when it has any unsaved changes. Note that when creating a new Item, its state is initially clean until a change is made. However, when creating a new Activity, its state is initially dirty to allow saving of an empty Activity.
Returns: boolean 
authorApp.safeToUnload(true);

Saves the current Item being edited.

Returns true (boolean) if successful, or false (boolean) if unable to save the Item (e.g when not on Item edit view or Widget edit view, no changes to save in an Item, Item is empty).

Sets the Item JSON.

Returns true (boolean), if it started updating or false (boolean) if unable to set the Item JSON. It will return false if the Item reference in the JSON is invalid or if the user is not in the Item edit view.

Calling this method will apply the Item JSON to the Item currently being edited. Therefore, this method won't allow you to switch between Items. If you want to set the JSON of a different Item, you must first navigate to that Item.

Returns: boolean 
authorApp.setItemJson({
    "item": {
        "reference": "example-item-1",

Set the widget JSON of the widget being edited in an Item. This only works with Question Editor v3.

setWidget accepts an object specifying a template_reference key for the template as a second argument. If this is set, the widget is displayed within the template specified by the argument. Use that approach if you have custom template (with hidden sections, fields, etc.) set up as reference of QuestionType inside question_types.

Returns true (boolean) if successful, or false (boolean) if unable to set the widget JSON (e.g. when not on Tile view or Widget edit view)

Parameters
widgetJson
Type: widgetJson

Properties of the widget JSON vary depending on the Question type or feature type. See Question Types and Features Types in Questions API for more information.
