Triggering a javascript / JQuery function when a particular option is chosen from a select dropdown

If I have a web form that contains a select dropdown in that has an ID attribute of "shipping_state":

<select name="shipping_state">

Open in new window


How might I customize that form so that when a person chooses the state of Florida from that dropdown ..

<option value="FL">

Open in new window


.. a custom javascript function gets triggered?

Ideally .. I would prefer a solution that do NOT require that I modify the form itself.  

I am open to solutions that require JQuery if that is the best approach.  Otherwise, plain old javascript will do.

Thanks in advance.
