[jQuery] Can I use a reference to a select id in a function like this?

[Rick Faircloth]

I have a select with id="agentSelect" and onchange="updateDutyRecord()".  Once 
I choose
an option, can I reference the select and option like this?


function updateDutyRecord() {           
                        
     $('#agentSelect', this).change(function() {

          $('option:selected', this).each(function() {
