you can just plain javascript like this for an alert on the button: onclick="alert('hello')"

• or for anything fancy I would seriously consider using jQuery dialogs for it. You define the content of the dialog in a hidden div on the page and use a script to attach the dialog to the div by id. Have a look at

http://docs.jquery.com/UI/Dialog

you can use alert(message) function through javascript to show any message

alert(message) or confirm(message) are useful javascript functions. Alert just shows the user a message, whereas confirm displays a confirmation box and allows you to get a boolean value back from the user.
