Jquery Super box automatically loads

Question

The superbox is a jquery plugin that has lightbox effect. My problem is how can I change this thing instead of click, it will automatically loads when the page is executed. The code rel in <a> is required. How can I set that to onload or automatically popup when I visit the page.

My Code:

<link rel="stylesheet" href="css/jquery.superbox.css" type="text/css" media="all" />
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/jquery-superbox-0.9.1/jquery.superbox.js"></script>
<script type="text/javascript">
$(function(){
  $.superbox();
});
</script>
<a href="forgotpass.php" class="text-links" rel="superbox[iframe]">Click here.</a>
