Select elements typically have two values that you want to access. First there's the value to be sent to the server, which is easy:
$("#pcdsselect").val(); // => 1
The second is the text value of the select. For example, using the following select box:
<select id="pcdsselect"> <option value="1">Mr</option> <option value="2">Mrs</option> <option value="3">Ms</option> <option value="4">Dr</option> <option value="5">Prof</option> </select>
If you wanted to get the string "Mr" if the first option was selected (instead of just "1"), you would do that in the following way:
$("#mpcdsselect option:selected").text(); // => "Mr"
