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.AuthenticationCompletedEventArgs = function();


The AuthenticationCompletedEventArgs class exposes an auth property, which in turn exposes the state property. From the state property you get an AuthState value, which indicates the status of the completed authentication operation.

The following example demonstrates a function that is called after authentication is completed. The function takes an AuthenticationCompletedEventArgs object as an argument. The example also demonstrates how the AuthState value is used to display an appropriate message to the user.

function appAuthenticated(authenticationCompletedEventArgs) {
    var auth = authenticationCompletedEventArgs.get_auth();
    switch (auth.get_state()) {
        case Microsoft.Live.AuthState.authenticated:
            alert("Authentication completed.");
        case Microsoft.Live.AuthState.failed:
            alert("Authentication failed.");
            alert("Authentication unsuccessful.");
