Get a value from dropdown selected in jquery [duplicate] - php

Question

I need to run a jquery function if a certain dropdown option is selected.
<select name=dropdown size=1>
<option value=1>option 1</option>
<option value=2>option 2</option>
</select>
I have the commands in the function ready, Im just not sure on how to make it so if option 2 is currently active in the dropdown, then run the function.
(dropdown doesnt have a submit button, i want it ran when the user highlights the option)

A simple way can be as following:

<option value="/en">English</option>
<option value="/ps">Pashto</option>
</select>
