how to show action message using a popup window

[javatwo]

Hi,
For <a4j:commandButton>, after user clicks the button, an action is executed and output a message. How to show the message on the client using a pop window, such as alert("success").

The property oncomplete="javascript-code". Can it bind to action message?

thanks!
