Namespace:  Microsoft.Live.Services

The JavaScript Library for Windows Live Messenger Connect is built by using the Microsoft Ajax Library. Microsoft Ajax exposes a type system that enables you to add object-oriented capabilities to your JavaScript code. To learn more about creating, instantiating, and deriving from classes, see Creating Custom Client Script by Using the Microsoft Ajax Library.

Microsoft.Live.Services.AddVideoActivity = function();


The AddVideoActivity class is used to read or create an activity that represents a video. The arguments of the constructor method of the AddVideoActivity class encapsulate all of the information needed to specify the video activity. To create an activity that indicates that a video was played, use the PlayVideoActivity class.

For more information about the specification for this object type, see "Video" in Atom A.

An AddVideoActivity instance can contain one or more objects of class VideoActivityObject that describe the individual video activities. The video activity objects are accessed with the activityObjects property.

For more information about activities, see Activities Resource and Working with Activities (JavaScript).

The following example demonstrates how to add a video activity to an existing activity collection.

function addVideoActivity() {
    if (myActivitiesCollection) {
        var timestamp = (new Date()).toTimeString();
        var previewLink = '' + timestamp;
        var alternateLink = '';
        var title = "video title";
        var videoActivityObject = new Microsoft.Live.Services.VideoActivityObject(previewLink, alternateLink, title);
        videoActivityObject.set_description("video description");
        var videoActivity = new Microsoft.Live.Services.AddVideoActivity([videoActivityObject], '');
	if (myActivitiesCollection.isValidType(videoActivity)) {
        else {
            alert('invalid video activity');
