Chosen.js referencing an option value

has anyone any experience with chosen.js? : http://harvesthq.github.com/chosen/

An issue hopefully someone can point me in the right direction..

<select title="Choose a Body Part" id="body-chart-dd" style="width:295px;" tabindex="2"> <option value="a1">Face</option> <option value="a2">Legs</option> </select>

It just generates <li id="body-chart-ddchzn_o_1">Face</li> etc .. How can I grab the a1 ... a2 values? Thanks in advanc开发者_Go百科e

$("#body-chart-dd option").each(function(){

alert($(this).text());
});
