Need help combining js functions...

[AshleyQuick]

Using this:

clip.addEventListener( 'onMouseDown', my_mouse_down_handler );
    function my_mouse_down_handler(client) {
        alert( "mouse button is down" );
}

How can integrate this jQuery function so that the quick-alert div is displayed instead of alert( "mouse button is down" );?

$(document).ready(function() {
    $('#show-alert').click(function() {
        $('<div class="quick-alert">Alert Message</div>')
        .insertAfter($(this))
        .fadeIn('slow')
        .animate({opacity: 1.0}, 3000)
        .fadeOut('slow', function() {
                $(this).remove();
        });
    });
});
