Trigger TINY.box.show on $("#mydiv") from within $(document).ready(function()

Question

I have the following:

<script type="text/javascript" src="/js/tinybox.js"></script>

In tinybox.js I have:

$(document).ready(function() {

$.ajax({

$("#mydiv").TINY.box.show(params here...);

});

});

How do I call Tinybox from  mydiv in this example?
