Track chapters and segments using JavaScript 3.x track-chapters-and-segments-on-javascript

The following instructions provide guidance for implementation using 3.x SDKs.

If you are implementing any previous versions of the SDK, you can download the Developers Guide here: Download SDKs.
  1. Identify when the chapter start event occurs and create the ChapterObject instance by using the chapter information.

    ChapterObject chapter tracking reference:

    note note
    These variables are only required if you are planning to track chapters.
    table 0-row-3 1-row-3 2-row-3 3-row-3 4-row-3
    Variable Name Type Description
    name string Non empty string denoting chapter name.
    position number The position of the chapter within the content, starting with 1.
    length number Positive number denoting length of the chapter.
    startTime number Playhead value at start of chapter.

    Chapter object:

    code language-js
    var chapterObject =
  2. If you include custom metadata for the chapter, create the context data variables for the metadata:

    code language-js
    var chapterMetadata = {};
    chapterMetadata["segmentType"] = "Sample segment type";
  3. To begin tracking the chapter playback, call the ChapterStart event in the MediaHeartbeat instance:

    code language-js
    _onChapterStart = function() {
      tracker.trackEvent(ADB.Media.Event.ChapterStart, chapterObject, chapterMetadata);
  4. When playback reaches the chapter end boundary, as defined by your custom code, call the ChapterComplete event in the MediaHeartbeat instance:

    code language-js
    _onChapterComplete = function() {
  5. If chapter playback did not complete because the user chose to skip the chapter (for example, if the user seeks out of the chapter boundary), call the ChapterSkip event in the MediaHeartbeat instance:

    code language-js
    _onChapterSkip = function() {
  6. If there are any additional chapters, repeat steps 1 through 5.
