Events

The Author API exposes number of public events so you can trigger custom functionality.

The callback will be called with a PublicEvent instance as an argument (unless indicated otherwise), which provides access to event data. The Event Data column gives information of what can be found in the event.data object.
Event name Description Event data
activityduplicate:error

Fires after an Activity has failed to duplicate.

If this is a shallow copy, this fires after the save:activity:error event. If this is a deep copy, the save:activity:error event doesn't get fired at all.
  • Error - object
    Information about the error.
activityduplicate:success

Fires after an Activity has successfully duplicated.

If this is a shallow copy, this fires after the save:activity:success event. If this is a deep copy, the save:activity:success event doesn't get fired at all.
activityedit:item:create
Triggered when the “Create Item” button is clicked in the Activity Editor.
activityedit:item:edit
Triggered when an Item reference or title is clicked in the Item list of the Activity Editor.
activityedit:items:added
Triggered when the “Add Items” button is clicked in the Item picker of the Activity Editor.
activityedit:saveable:changed

Triggered when the Activity becomes either saveable or not saveable. It is also triggered when the Activity edit view is rendered.

This event is controlled by the same conditions that control whether the Author API's save button is clickable. Since these conditions could change, this event may behave differently in different versions of Author API.

Therefore, this event is useful if you are creating your own save button and you want it to behave similiar to the Author API save button.
  • saveable - boolean
    Indicates whether the Activity can be saved, either via the saveActivity() public method or the save button.
add:widget
Triggered after an author clicks on the add widget button. Use event.preventDefault() to block adding widgets and prevent unexpected behaviour.
  • region_id - string
    ID of the region to which the widget has been added.
itemduplicate:confirm
Triggered after an author confirms duplication of an Item. This is only fired if the Item contains a shared passage.
  • itemJson - object
    JSON of the Item being duplicated.
itemedit:changed
Triggered after an author changes the Item layout, dynamic data or Item tags.
navigate
Triggered when the app location changes, e.g. when visiting an Item from the Item list; when doing a search; when going back from an Item to the Item list; etc. Can use event.preventDefault() to prevent navigation.
  • location - string
    Latest location.
  • locationEncoded - string
    URI encoded version of latest location.
  • route - string
    Matching route (See list of routes).
open:activity

  • activityJson - object
    JSON of the Activity being opened.
open:item
Triggered when an Item in the Item list is clicked. Can use event.preventDefault() to prevent the Item from being opened.
  • itemJson - object
    JSON of the Item being opened. This does not include questions or features.
render:activity
Triggered after an Activity has finished rendering.
render:activitylist
Triggered after the Activity list has finished rendering. The event is triggered after the first load of the Activity list, every search, sorting, and when loading additional pages.
render:item
Triggered after an Item (including any questions or features it contains) has finished rendering.
render:widgets
Triggered after only widgets (Questions and Features) are re-rendered in an Item (e.g. when navigating from edit to preview mode). This event is not triggered if the whole Item is rendered (e.g. when navigating from Item settings back to Item edit).
  • widgetReferenceList - array
    Array of widget references which were re-rendered. Widgets in the DOM have a span with attribute data-authorapi-widget-reference set to a reference in the list. You can search for like so:[data-authorapi-widget-reference="some-widget-reference"].
render:itemlist
Triggered after the Item list has finished rendering. The event is triggered after the first load of the Item list, every search, sorting, and when loading additional pages.
save
Triggered before an Item is to be saved. Can use event.preventDefault() to prevent the Item from being saved.

If the save event is triggered when editing a Question or Feature, function preventDefault accepts an optional argument {discardWidgetChanges: true/false}. If set to true, the modifications of the Question/Feature are discarded. The default value for discardWidgetChanges is false.
