How to use Messi.ask()

[perthsystem]

Hi,

I have

setup to display when user clicks on a link eg.:
a href="javascript:void(0)" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display='block'" title="This week's video"></a

This works well, however I would like to use Messi.ask() to ask the user to confirm to continue. 'Yes' would display the div id="light" class="white_content" and 'No' would not.

Is this possible?

Many thanks :)

If I understand this correctly, you can do something like this:

Messi.ask(
    'Would you like to continue?',
    function(value) {
        if (value == 'Y') {
            document.getElementById('light').style.display='block';
        }
    }
);
