Need help combining js functions...

Using this:

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

Code (markup):

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();
		});
	});
});
