JQuery :: Using GET Data To Decide Where To Put Selected="selected"?

I need some jQuery code to get the data from the URL (example.com/?areaCode=1234) and then use it to add selected="selected" to the correct option from this set.

<option value="1111">one one one one</option>
<option value="2222">two two two two</option>
<option value="3333">three three three three</option>
<option value="1234">one two three four</option>

I hope you understand, it's quite hard to explain even though its super simple.
I can do this in PHP by doing<option value="1234" <?php if($_GET['areaCode'] == 1234) { echo 'selected="selected"; }>one two three four</option>
